Retrofit Smart Home: Washing machine reports finished laundry Standby consumption as an alarm trigger Laundrify: Ready-to-use solution for the washing machine AVM FritzDECT: Connect the washing machine to the Fritzbox Telekom Magenta SmartHome: false alarms unavoidable Homematic IP: additional service required Conclusion If your washing machine is doing its rounds in the basement or a room further away, you will not know whether it has already done its job. Modern washing machines counter this with integrated WLAN interfaces and manufacturer apps that keep you up to date. However, if you are using an older model, you do not need to consider buying a new one. You can retrofit the function yourself with the help of smart home components.

For this you need a smart adapter that determines the energy consumption of the washing machine and makes the measurement data available to automation software. We wanted to know how well it works. We therefore looked at what the ready-to-use Laundrify solution and the smart home systems AVM FritzDECT, Telekom Magenta SmartHome and Homematic IP make possible.

Standby consumption as an alarm trigger The hurdle is to find a suitable variable that clearly signals that the machine is now closed. The most obvious is the power consumption in standby mode. Because it can be measured reasonably reliably. This means the amount of watts that the machine draws from the network when it is switched on and supplies the controls with power – but does nothing else.

Tablets for … Tablets Tablet with … Stylus Additional accessories Headsets Tablet stand … Keyboards Mice Conclusion Comments from Stefan // 21. 01. 2021 16: 19 Clock

Regardless of whether it is a sofa tutor, the Studienkreis Online-Lernbibliotek or the school minator – learning portals can be a useful alternative to traditional tutoring for school children of all ages. We show the best tablets for it.

If the child is weak at school, there are several alternatives. In addition to personal initiative, this primarily includes follow-up sessions in learning groups such as the study group or individual tutoring, as offered by many older pupils or students. However, especially in times of epidemics, contacts with strangers must be restricted as far as possible, so traditional tutoring is usually ruled out.

What are learning portals? In addition to homeschooling (guide: PCs for homeschooling from 150 Euro) there are also digital solutions for tutoring in the form of learning portals. Depending on the provider, they usually offer help for grades 5 to 10, which is usually available in text and video form for several subjects. Some companies go far beyond this and have offers for all classes and types of school as well as most of the subjects offered at the various types of school.

Sometimes there are also educational games and, in most cases, exercises to check and consolidate what has been learned. In addition, some portals also offer personal support via chat, help with homework or complete individual lessons via video chat.

Providers such as Lernwerk, Schulinator or Studyhelp even offer their services free of charge, most others charge between 5 and 25 Euro. Free test phases or even some videos published on Youtube offer first insights into the type and quality of the offer. Payment is usually made for several months in advance or in an annual subscription, some providers even give a money-back guarantee in the event of a lack of learning success.

PC or tablet? A PC is not always necessary, a much cheaper Android tablet is easily sufficient for learning videos. However, some criteria should be met so that the tutoring is fun on the technical side. This is how we see tablets with a display size below 10 inch (approx. 25 cm) critical and also a display resolution of 1920 × 1080 Pixel should not be undershot for sufficiently sharp display. The devices should have at least a quad-core processor and 2, better 3 GB of RAM so that inputs can be implemented without waiting time and videos can be played smoothly. Internally is a memory size of 25 GByte or Larger is optimal, so that apps and videos can also find space in the memory and can be used without direct Internet access.

WLAN as Internet access should be sufficient in most cases, so parents can safely ignore expensive LTE modules. For young students, it may be worthwhile to use particularly robust, but hardly available, children’s or outdoor variants. Alternatively, there are protective covers or tablets for children. Amazon offers the kids edition of its Fire HD tablets for this purpose. Not only do they last longer, they also allow parents to access and block certain distracting factors such as the app store and in-app purchases. For certain subjects or advanced students, purchasing a tablet with pen control can also be helpful. This enables sketches or handwritten notes to be digitized quickly. The requirements of the individual providers or the school are usually revealed on their homepages.

Tablets for children The kids editions of Samsung and Amazon offer, as mentioned, special protective covers that are supposed to protect the tablet even when used in rough conditions and also offer various parenting functions such as restricting the available apps. Unfortunately, the RAM is a bit tight at 2 GB. They are more aimed at children who are not yet in secondary schools. However, they are sufficient for the use of normal learning portals. The Fire HD 10 in the Kids Edition (test report) we have already tested it.

Tablets For round 150 to 200 Euro get those interested with the current models Odys Space One 10 LTE , Lenovo Tab M 10 Plus and Samsung Galaxy Tab A7 three 10 – Customs tablets that are up-to-date and meet the minimum requirements required by us. The Odys model not only offers a lot of memory (4 / 49 GByte), but also an LTE module. This allows learning sessions – a corresponding LTE contract (Article: Unlimited data volume from 20 Euro) provided – in good weather also in the park or at least in the garden. Android 10 is already available from the factory – this is far from normal with tablets.

That shows something like this Lenovo Tab M 10 Plus , which is currently only Android 9 offers. The remaining specifications are marked with 4 / 64 GByte memory similar, only LTE does not exist. This is also the case with the Samsung Galaxy Tab A7 so, also the memory is with 3 / 32 GByte slightly smaller. There are advantages for the chipset: The other two tablets also offer 8 cores, but Samsung uses a Snapdragon 662 that does not only delivers decent power, but also favors future updates and is less power hungry. Accordingly, auc h this model already has Android 10. With 10, 4 inches, the screen of the Samsung tablet is also the largest, this also applies to the battery with 7040 mAh.

We have other suitable tablets in our purchase advice: How many tablets do you need? sorted by price. The price scale is largely open at the top. If you don’t like Android, you should look around at iOS models, i.e. iPads. The cheapest current models are iPad Mini (test by Mac & i) and iPad (without name affix), they cost from 379 and 449 Euro. The larger and more modern models iPad Air (test by Max & i) and iPad Pro start at 649 and 879 euros. However, we would exclude the iPad Mini as a tablet for homeschooling because of the display size of only 7.9 inches.

Tablet with pen Tablets with additional pen control are available in a handful, current and Currently, the Samsung Galaxy Tab S6 Lite . It not only offers advantages in terms of design and installation depth, but also a stylus with suitable software and more memory.

Stylus A stylus can be helpful to make drawings or handwritten notes directly on the tablet. With some models, such digital pens are already included from We rk, while others are prepared for operation, but the pen must be purchased separately. Such models are about d as Apple iPad ( from 6th generation) , iPad Mini (from 5th generation), iPad Air (from 3rd generation) or the iPad Pro , here the pens cost between 90 and 120 Euro.

Simple capacitive pins without egg Genetic power sources are much cheaper, they b e start at a few cents. They work on any device with a capacitive touchscreen and usually have a thick, soft rubber tip . So that become they recognized as finger replacement on current touchscreens . Special pens with rechargeable batteries or batteries, however, have a thin , mostly exchangeable Tip, which also recognize different pressure levels and often buttons for additional options (such as “erase” when Hold down ) bid. With them the handling is much more similar to a normal pen on paper than with the former Pens. Examples of high-quality tablet pens are Samsung’s S-Pen or Apple’s Pencil. In our guide to pens for the iPad we show cheaper alternatives to the Apple Pencil.

Additional accessories As with the PC, there are also peripheral devices for tablets. They are not absolutely necessary, but make everyday life easier.

Headsets If you want to concentrate on your work or if you have to understand everything in the video call despite the poor sound quality of your conversation partner, you should consider purchasing a headset. Many tablets also offer a 3.5 millimeter jack connection so that the cable headset from the smartphone can also be used in an emergency. Wireless headsets that are connected via Bluetooth are more practical and usually also of higher quality. Headphones with active noise suppression in particular (best list ANC headphones) can even promote concentration as they minimize external distraction.

Due to the design, over-ear headsets are best. They cover the whole ear, are usually still comfortable when worn for a long time and already shield something from the environment. They are also available with and without cables and also with ANC. The advantage of wired headsets: You do not have batteries that are always empty exactly when they are needed. But they are less flexible and the mandatory cable always hangs in the way.

Tablet stand and cover One advantage of tablets is their flexibility by comparatively low weight and size. However, if the children are to follow the learning video and complete test tasks, the device must be stable can be found. That works either with separate stands, Book c overn or equal to a keyboard cover. Stands are self-explanatory: They are external rne constructions that only serve the purpose of placing a tablet more or less straight in front of you on the table. A book cover protects the tablet during transport, thanks to the flexible cover usually also the display. In addition, the device can also be set up in front of you on the table, often there are even different adjustable angles.

Keyboards Thanks to Bluetooth, a keyboard can be wirelessly connected to any tablet, regardless of whether it is Android, iOS or Windows. You have a wide choice. This ranges from simple, classic keyboards to those that are extremely flat to ultra-compact TKL keyboards with mechanical switches. More on this in our keyboards guide: Mechanical, rubber dome or TKL? or multimedia keyboards for Smart TVs and Media PCs.

The keyboard or keyboard c over added to Bookcover another mechanical full keyboard, which connects to the tablet via Bluetooth. Especially when longer texts are to be written on the device s , is a mechanical keyboard significantly better than the onscreen cords of the T ablets. For home Bluetooth keyboards without a protective function are usually sufficient.

Mice What applies to a laptop is no different for a tablet: touchscreen and / or touchpad Operation is okay, mouse control is often more ergonomic in the long run. Since most tablets lack the large USB-A ports, mice with USB C (or adapter) or Bluetooth mice are required. With a keyboard and mouse, a cheap tablet almost becomes a real office PC, but for the sake of simplicity, users can simply leave the accessories at home for on the go. So you always have the best of both worlds at hand.

Conclusion It doesn’t always have to be a full-fledged PC, even comparatively cheap tablets can help improve school success. In addition to the appropriate learning portal, parents should also keep an eye on the right hardware – if you set too low, you may buy a new one after a short time.

Should it be a new PC for homeschooling? Then we have the right tips and recommendations in this article.

Oppo is hardly known in this country, but some models offer real top performance. The Oppo Reno 4 Pro comes with about 12 / 256 GByte memory, great OLED screen and flagship camera.

Oppo, Vivo, Realme – all Chinese brands that have just hit the German market and want to cut a piece out of the Huawei cake. Thanks to great technology and chic design, it actually works very well. If the price is right, the manufacturer and customer are happy.

At Oppo it is a little different. For the Oppo Reno 4 Pro, the manufacturer demands a full 750 Euro in the RRP – and that, though no top chipset, no IP 68 certification and no wireless charging included. In the test, we show why the purchase is still worthwhile.

Design It is chic, the Oppo Reno 4 Pro, there will probably be little counter-argument. With a depth of only 7.6 millimeters, the smartphone is really thin and the remaining dimensions of 160 × 72, 5 millimeters is moderate for a device with a 6.5-inch display. In addition, the device weighs just once 172 Gram – for all heavyweights with 172 + grams this is very positive. In addition, there is a high-quality material impression. The frame with its stylish bevels on the front and foot sides is made of aluminum, the front and back are protected against scratches with Gorilla Glass 5. Because of the rounded sides, which are quite gentle for an edge display, the frame on the sides is very narrow and the smartphone looks even more delicate.

There is also a chic back with a matt finish and gradient. Our blue test device therefore changes between medium blue and turquoise depending on the incidence of light. Thanks to the matte surface, fingerprints and other ugly fat deposits are not an issue. The great overall impression is crowned by the very good workmanship. The transitions between the different materials can only be felt minimally, there are no sharp edges. The only exception here is the protective film that sticks to the screen at the factory. It can be easily removed. The keys embedded in the side of the frame sit tight and wobble-free, the pressure point and key travel are exemplary.

Together with the evenly narrow frame around the display, the punchhole notch and the chic design, the Oppo Reno 4G is currently one of the highest quality models on the market. It is a pity that the manufacturer only offers IP protection against water and dust 54 elects. A brief downpour is not a problem, but the device must not fall into water.

All pictures of the Oppo Reno 4 Pro in the test (23 Pictures) Display The screen has a diagonal of 6.5 inches. With a resolution of 2400 × 1080 Pixel results in an image sharpness of just over 400 ppi (pixels per inch), that’s sharp. In addition, thanks to OLED technology, the display shines with strong contrasts, an excellent black level and, if desired, strong colors. In the default setting, the color rendering is quite natural. Class is the brightness: are round 500 cd / m2 in manual Mode still not very impressive, it is the measured 696 cd / m2 in automatic mode. In combination with the very good viewing angle stability typical of OLEDs, users have no problems reading content even in direct sunlight.

We liked the display in the Oppo Reno 4 Pro: The screen has a refresh rate of 90 Hertz, provides moving content more fluidly than models with 60 Hertz. In addition, the smartphone’s always-on display and its general setting options for the display are a plus point.

Camera Oppo does without data sheet prettiness with macro or depth sensors and builds an honest triple cam into the Reno 4 Pro. It consists of the main lens with 45 Megapixels, optical image stabilizer and f / 1.7 aperture, wide angle with 12, 2 megapixels and f / 2.2 as well as telelens with 13 Megapixels and f / 2.4. In front comes an optic with 32 Megapixels used.

The main camera is very good, the additional lenses are good The quality of the main camera is convincing. Image sharpness, level of detail, color reproduction and image noise are all on a very high level, and the image dynamics are very good. This puts the main camera of the Reno 4 Pro at the top level. This also applies with only slight drawbacks in poor lighting conditions, but here some high-priced competitors are a bit better, for example the Huawei Mate 40 Pro (test report). Unfortunately there is one for telephoto and wide-angle lenses n slight decrease in quality, and the coordination of the individual lenses with one another is not perfect. The result is that the telelens, for example, captures images in the memory with a lighter color and less color – this shouldn’t really happen with a smartphone in the upper price range. Overall, the image quality of the additional lenses is still good, but they do not come close to the quality of the main lens. The main disadvantages are image sharpness and image dynamics.

All original recordings with the Oppo Reno 4 Pro (37 Pictures ) The same applies to the front camera. Although it delivers very attractive images overall, it looks a bit too fishy and the image sharpness should also be higher. The main camera delivers decent, but not overwhelming results for videos. This is also due to the fact that with 4 / 30 is over and pans are never sharp. The image stabilization, like the other image quality, is otherwise arranged in the upper third of the smartphone range and therefore fits the price.

Furnishing The quality of the Oppo Reno 4 Pro is excellent, the display is great and at least the main camera is top-notch – can the rest of the equipment keep up? Mostly yes, but not in all cases. Users have to make slight compromises with the chipset. Because despite the rest of the equipment of 12 GByte RAM (!) And 256 GByte of internal memory, the manufacturer does not use the top chip Snapdragon 865 (+), but “only” on a Snapdragon 765G. The eight cores of the chip clock at up to 2.4 GHz, one Adreno 620 ensures sufficient everyday performance. For gaming, the chip with a G in its name offers a few advantages that are supposed to provide more power and faster loading times compared to the same chip without a G.

Overall, most games can be played smoothly, but for a few exceptions an 8-series chip would have been desirable – also with a view to the RRP of the Reno 4 Pro. Unsurprisingly, multitasking is not a problem with the amount of memory, but it hardly has a positive effect in benchmarks. In PCmark Work 2.0 the device reaches around 7900 points, that is roughly on par with other smartphones with Snapdragon 765G. The same applies to Antutu, here the model reaches about 256. 000 Points.

Apart from that, the Reno 4 Pro offers a comprehensive technology package with WLAN ac, Bluetooth 5.1, location via GPS, Glonass, Beidou, Galileo and QZSS as well as LTE and 5G. Instead, savings are found in the details. The ample internal (non-expandable) storage only has a UFS 2.1 speed, Wifi 6 is missing and the USB-C port only offers 2.0 standard. There is dual SIM capability and stereo speakers for this. They are loud and powerful, but the competition is a bit better here at times. The fingerprint sensor in the display is well implemented. It works quickly and reliably with light pressure.

The user interface Color OS 7.2 is above Android 10, an update to Android 11 did not exist yet. The security patch is as of December 2020 pretty up to date. Compared to before, Oppo has improved its update supply and now regularly brings patches. The Color OS interface offers a number of additional functions, but does not appear overloaded, but modern. There isn’t much bloatware on the Reno 4 Pro.

Battery pack The 4000 mAh of the built-in battery does not sound particularly impressive and it is therefore not surprising that the Oppo Reno 4 Pro does not Is cross-country skier. Nevertheless, the smartphone achieves better endurance values than some competitors with a stronger battery pack. The device comes in the PCmark battery test at 200 cd / m2 on almost 9 hours with an active screen and a brightness of 80 to 20 percent – that is with activated 90 – Hz function of the screen is a decent value. The good benchmark result was confirmed in the test. Transferred to the test routine, the device is definitely good for one, with minimal restrictions even for two days without an external power supply.

A bit of a shame with the price shown: There is no wireless charging. But the Reno 4 Pro offers another highlight: fast charging with full 65 Watt. This means that the device fully charges again in barely more than half an hour and intermediate charging is like a sprint from Usain Bolt in his best days. This is impressive.

Price It already sounded: The EIA of the smartphone is proud 799 Euros, but the street price is now significantly lower – as long as it doesn’t have to be the newer color variant Green Glitter. Otherwise there is a choice of blue and black, there are no technically different variants.

Conclusion The Oppo Reno 4 Pro is a really great smartphone that you can hardly blame. The biggest point of criticism is the price: 799 Euro RRP for a manufacturer who does not yet have a name in this country, also no wireless charging, no IP 67 and no top chipset? It’s just too much. The situation is different with the street price at which the device has now leveled off. That is more or less significantly below 600 Euro, even offers just below 500 euros already existed.

In return, buyers receive an absolutely chic smartphone, which also impresses with a great display, an extremely large amount of memory, a top-quality main camera with good additional lenses and an extremely fast-charging battery. The device competes with models such as the Oneplus 8T (review) or the Oppo Find X2 Pro (review) from our own company. Models like the Xiaomi Poco F2 Pro (test report) show that models with top chipset can be significantly cheaper.

heise + | Six routers for Wi-Fi 6 in the test

With Wi-Fi 6, the WLAN should transmit more smoothly. Five inexpensive routers showed what they can do and where there are still problems compared to a top-class device.

(Image: Andreas Martini)

If the WLAN can no longer keep up with the upgrade of the Internet connection, you have to use a new router and thus the current WLAN generation Wi-Fi 6 Near. We asked half a dozen devices into the laboratory, whereby we set two mandatory criteria for the selection: DFS and WPA3. A router in the 5 GHz band is only allowed to use all channels with Dynamic Frequency Selection – automatic channel change when radar is detected. This enables him to avoid neighboring WLANs better, which benefits the throughput of both networks.

The WPA3 WLAN encryption protects WLAN clients better than the old WPA2, including with Protected Management Frames (PMF ) and Perfect Forward Secrecy (PFS). PMF prevents an attacker from logging clients with falsified control packages from the base and redirecting them to their own honeypot. PFS ensures that recorded encrypted traffic cannot be subsequently decrypted even if the WLAN password is known.

The tested routers should not exceed 200 cost euros and offer Wi-Fi-6-WLAN in both radio bands. Devices that could not handle DFS or WPA3 flew out of the test field again. First it hit the RAX 39 from Netgear. It could do DFS, but failed because of WPA3. In the version notes of the firmware 1.0.3 current at the start of the test. 88 we found: “This firmware version does not support OFDMA, WPA3, and Smart Connect.” In view of the OFDMA capability promised on the box, this can only be described as disappointing. The Edimax BR – 6473 AX and the TP-Link Archer AX 50 had to say goodbye because they lacked DFS and WPA3.

TechStage tests the multi-room loudspeaker and says who should strike and for whom other Sonos products are worthwhile.

In addition to the simple symphonic Speakers (test report) Ikea has developed a second device with Sonos. The big difference: There is an E on the speaker 14 – version, next to music it also emits light. Nevertheless, the idea is not bad and the price of the Symfonisk table lamp is on par with a Sonos One SL.

We test the network loudspeaker as part of our Multiroom theme world. Not only other tests on Sonos products appeared there, such as the Sonos Arc (test report), the Sonos One (test report) or the battery-powered Sonos Move (test report). We also take a look at other multiroom systems there, such as Denon Heos (test report), Yamaha Musiccast (test report), Teufel Raumfeld (test report) or speakers that connect directly via Spotify Connect.

Design and technical data The symfonisk light consists of three parts: A wide, plate-like base with the three control elements volume up, volume down and start / pause. The loudspeaker sits on top of it in a cylindrical shape, which is interrupted by the rotary switch for the light on the side. Finally, at the top is the lampshade. It has a broad base and tapers towards the top, reminiscent of a classic floor lamp. The lamp takes bulbs with an E 13 – socket with a maximum of 7W. This makes it bright enough to be used as a reading lamp. Opinions are likely to differ on design. In the editorial team and among friends, opinion fluctuates between “cool” and “looks like a toilet paper holder”. However, the device does its job well, both as a lamp and as a loudspeaker.

Left the Symfonisk light, right the Symfonisk loudspeaker. It is important to know that the lighting function is completely separated from the Sonos and Multiroom features. The audio is played back in the classic way via the Sonos app for Android, iOS, Windows or Mac OS. The lamp can be switched on or off using the rotary switch on the side. Smart functions or automatisms for light are missing. However, this can be retrofitted with smart lamps.

On the back, next to the power connection, is the typical Sonos network connector, but in most cases you will probably use the WLAN for access to the network use.

Setup and Sonos integration As with the Symfonisk loudspeaker, there is a complete Sonos system in the multiroom lamp from Ikea . In other words, the luminaire can be completely controlled via the Sonos app and is compatible with all of the manufacturer’s other products. Whether as a multiroom group, as a stereo pair or in combination with a soundbar, on the app side there is no difference between Sonos directly from the manufacturer and Sonos from Ikea.

The setup is accordingly simple. In the Sonos app, go to “Add system” via the settings and then follow the instructions in the app. It’s easy and done in a few minutes. Then you can choose the name and / or the location. If available, a firmware update will be installed.

The buttons for the typical Sonos commands are on the wide coaster. sound The sound body of the Symfonisk lamp creates a surprisingly good sound, especially in the bass range. Here the Symfonisk lamp even creates a little more bass than the comparable Sonos One SL. However, it lacks protection against splash water or the Alexa microphones of the Sonos One (test report). Still, the sound is very good, as you would expect from a Sonos device. In other words, streaming is not a problem, but anyone who prefers to listen to vinyl or is one of the particularly audiophiles will have to resort to another solution.

In addition, there is an equalizer in the apps for Android and iPhone, with which you can, for example, turn down the bass a little. Users of iPhone and iPad or other Sonos products such as the Sonos Arc (test report) can also use the Trueplay features to automatically measure the loudspeaker. This is particularly useful if you use the lights as back speakers for the Sonos soundbars to transform the virtual 5.1 into real surround sound.

Conclusion Unlike the Symfonisk speakers, the Symfonisk table lamp has direct competition in the Sonos One SL, both cost about 181 Euro. Accordingly, you have to decide what you want. The Symfonisk table lamp is significantly larger than the loudspeaker, but has the great advantage that, thanks to its light, it is not only a loudspeaker but also a piece of furniture. If you want that, you can get a good table lamp with a very good multiroom speaker and one of the best apps for control.

If you are looking for a cheaper Sonos speaker, we definitely recommend the Symfonisk speaker (test report), which is less than 100 Euro costs. Otherwise, we recommend taking a look at the guide to multiroom systems: Sound in every room.

Cluster recording: New app enables corona tracing at larger meetings

The Berlin start-up Videmic has published an app of the same name for tracking corona infection chains in large crowds in the App Store and on Google Play. The mobile tracing application saves stays in busy locations in the app’s user profile and thus enables cluster recording without scanning a QR code, as is necessary with the open source solution CrowdNotifier. Locating by GPS is also not required.

Proprietary technology records encounters Virus infections mainly take place in places where there are many people. However, this is exactly where the German government’s Corona Warning App (CWA) reaches its technical limits: In order to save energy, it only “listens” for codes for relevant encounters at very generous intervals. The distance measurement via Bluetooth is also not particularly accurate. On the basis of the given parameters, a longer meeting would only lead to a low risk assessment, even in a poorly ventilated room, if the people are not sitting close together.

In contrast to the CWA, “Videmic Tracing” does not use the Interface for the Covid 19 notification system (Exposure Notification Framework) integrated by Apple and Google in iOS and Android. It uses a proprietary solution with Bluetooth and WLAN to record encounters. The network access data generated by these technologies is used to approximate the location of a user.

For this, the solution evaluates the identifiers of the WLAN hotspot and the Bluetooth MAC Address (Media Access Control). In the normal user mode, this data is only temporarily stored during a stay at an event or with a Videmic partner and then deleted.

Encounters recorded decentrally More exciting is the chargeable “channel mode”, which masters the often requested clustering. A six-digit, individual access code is required for this. In this mode, the tracing app maintains Bluetooth connections to all other nearby iPhones and Android devices on which the application is installed. Users must also have successfully logged in. In addition, the app operates a temporary WLAN access point for clustering, for example in a lecture hall or at a trade fair stand. IP addresses are only temporarily stored during data transmission.

The channel mode can currently only be activated on Android smartphones. In this case, the app sends the set nickname or the “location” to all smartphones in the vicinity to record location data via Bluetooth and the temporary WLAN access point. These store this information if a user has stayed at the location for more than five minutes. The information on the encounter between people in spatial proximity can be determined implicitly and decentrally via the mobile phones from the location data collected.

Warning via external code Similar to the approach of the CWA, the warning is issued after obtaining a Tele-TAN by publishing a code that does not contain any information that can be used by external third parties. Due to the independence of Apple and Google, the transfer of personal data can only take place via servers in Germany. Furthermore, like the CWA, the app does not save any personal data centrally, explained Videmic managing director Silvia Wallner to heise online. After 14 days, the data stored on the visitors’ smartphones would be automatically deleted.

Videmic tracing is especially for events such as film – and music festivals, trade fairs, conferences, schools and universities as well as suitable for companies, emphasizes Wallner. The app can filter out and notify people with risk encounters from the digital visitor list. This would relieve the health authorities enormously.

The company has not carried out a data protection impact assessment. For acceptance in the app stores, however, the application “went through a rigorous assessment process”, said Wallner. Aspects to safeguard the privacy of the users would have played an important role here.

Costs arise depending on the size of the event Videmic Tracing celebrated its premiere in December at the Christmas lecture at the University of Bayreuth, a hybrid event with Federal Labor Minister Hubertus Heil (SPD). The university used the app for location tracking and live recordings. Originally 90 people should be present in the Audimax. The number had been reduced again in view of the corona measures tightened shortly before the date, reported the head of the start-up. Over a thousand participants would have followed the lecture online with the Videmic solution and zoom.

The application is free for event visitors. Organizers can use it in advanced mode for automatic contact tracking and the production of live recordings. The costs for this depend on the size and duration of the event. Wallner did not give any details.

1000 Euros are too much for a smartphone? No problem: There are for 500 Euros almost as good cell phones. We tell you what to look out for when buying.

The top models of the well-known manufacturers are of course in the spotlight. Samsung Galaxy S 20 Ultra (test report), Xiaomi Mi 10 Pro (test report) and Huawei Mate 40 Pro (test report) arouse desire because technically they combine the best of the best. A look at the price quickly makes it clear that the companies are being paid royally for it. Then the disillusionment quickly follows, because about 1000 Euro for a commodity such as a Smartphones cannot or do not all want to spend. That is also not absolutely necessary. Because with a little effort in the search (price comparison with filter) interested parties actually get models that can hardly do less, but cost far less. If you don’t want to go to this trouble, just read on.

Display In the price class of 400 to 500 Euros are resolutions Not to be found below FHD + – but hardly above either. With an average diagonal of around 6.4 inches, FHD + also results in a little more than 400 pixels per inch (PPI) and ensures sharp display even without 2K or even 4K resolution. As a technology, OLED is at the top of the list of requirements – not because IPS LCDs couldn’t be good, but OLED provides that extra little bit of black level, viewing angle stability, contrast and color intensity. LCD is therefore the exception in these price regions. More and more common: Panels with 90 or even 120 Hertz for a more fluid display of content. 144 Hz (at least in combination with OLED) remains reserved for high-priced gaming smartphones such as the Asus ROG Phone 3 (test report).

Power 6 GByte RAM are with androids Mandatory, 8 GByte between 300 and 500 Euro no longer a problem and now even 11 GB of RAM possible – the was reserved for high-end2 models not long ago. The drive should normally be a top chipset from the current or past year, such as Qualcomm’s Snapdragon 865, 855 (Plus) or Samsung’s Exynos 9810 / 9820. The counterpart of Huawei is the Kirin 980, Mediatek or other providers cheaper Chips are usually no longer found in this high price region. Exceptions are generally always possible. For example, some of the smartphones in our list rely on a processor that is somewhere between the upper middle and lower upper class in terms of performance, namely the Snapdragon 765(G). It hardly makes a difference in everyday life, so with the appropriate remaining hardware, this should not be an exclusion criterion. Only benchmark fetishists and hard core gamers are usually better served with top chips because of stronger GPUs.

Other equipment 128 GBytes are mandatory in the price region for Android smartphones, even 240 GByte getting more and more frequent. Expandability via micro SD or similar is no longer absolutely necessary, but most models still offer this. Otherwise everything that is available in smartphones is technically on board – often even 5G. We have already used all current 5G smartphones in our 5G guide: These 5G smartphones are already listed. However, users should think twice about this as an obligation for the specifications of their smartphone. In the absence of adequate expansion, 5G is still far from being available nationwide in Germany.

As always, the battery should be an important criterion when buying. In addition to the pure power in mAh, things such as the ability to charge quickly and the option of wireless charging are important here. When it comes to the topicality of the Android version, most devices are in our top 10 look quite good. Who on Android 04 is set, gets its money’s worth and also the first devices with Android 11 are e.g. u get. Actually, many more models from this list should switch to the current Android version, after all, all smartphones come from at most 2020.

Place 1: Realme X 50 Per OLED with 90 Hz frame rate, 2400 × 1080 pixels on 6.4 inches – the display of the Realme X 50 Pro (test report) convinced us. The camera also, albeit primarily under good lighting conditions. Unfortunately Realme follows the 2020 he trend, ordinary Camera modules like the 64 – Megapixel main camera , the 12 – Megapixel telephoto lens and the wide angle with 8 megapixels with lower resolution Macro lens to inflate quad cam. The manufacturer could have saved the latter, but at least the other three lenses are reasonable. Even at the front there is in addition to the front camera with 32 Megapixel another wide-angle selfie cam with 8 megapixels.

Donated as drive Realme the X 50 Per a Snapdragon 865, that of fabulous 12 GByte RAM is flanked. So nothing jerks. 5G is also included. The internal memory cannot be expanded, but for just under 500 Euro at the time of the item full 256 GByte internal memory . Electricity comes from a 4200 – mAh battery that comes with 65 Watts can be charged quickly . Android 11 Has Realme as update already played.

2nd place: Xiaomi Black Shark 3 The OLED measures almost 6.7 inches -Display of the Xiaomi Black Shark 3, the not only 90 Hz, spec ren also an increased sampling rate of 256 Hz. This is particularly important for a gaming smartphone so that inputs are implemented precisely and directly. The Black Shark also has special shoulder buttons especially for gaming. But the smartphone also cuts a good figure outside of gaming. This is how the device is operated by a Snapdragon 865 with 8 GByte RAM in this version, internally there is 128 GByte. 5G is on board.

The battery is marked with 4720 mAh slightly stronger than in the Realme – model in first place and loads the same way fast. An update to Android 11 there is noc h not and also with the camera is with the main lens (64 megapixels) and wide angle (13 Megapixel) Conclusion. The third lens is just a depth sensor.

3rd place: Xiaomi Mi 10 T Exceptionally on a 6.7 inch IPS LCD, but with a full 144 Hz Xiaomi sets the Mi 10 T (test report). Main and wide angle camera with 64 and 13 Megapixels convinced in the test, the macro camera as always not. The smartphone is fast thanks to Snapdragon 865 and 8 GB of RAM absolute, also here are the built-in 128 GByte memory not expandable. 5G is included, Android 10 on the other hand not yet. The 5000 mAh strong battery can be used with 33 Watt fast charging .

4th place: Xiaomi Poco F2 Pro The Xiaomi Poco F2 Pro (test report) no longer because the competition listed above is stronger in some points. Such shifts take place either because more powerful models have come onto the market or because the typical cheaper technical equipment is gradually pulling counterparties from higher price ranges into lower segments. The latter is the case here, and the better equipped version with 8 / 256 GByte against the trend has even become more expensive again and no longer fits into the 500 – Euro budget. But even the smaller version is by no means part of scrap iron.

The almost 6.7 inch OLED display with Full – HD – + – resolution offers HDR 10 + and did very well in the test. However, the screen only comes with 60 Hz to the customer – this is no longer state of the art. A Snapdragon serves as the drive 855, how much faster before hardly. Only with the main memory is more to be gained with other devices, but the 6 GByte RAM of the smaller version is still sufficient in everyday life.

The quad -Cam with up to 48 Megapixel and at least 5-megapixel macro lens delivers good results, 128 GByte internal memory is sufficient Space for apps. 5G is on board as well as a retractable pop-up front cam . The battery has decent 4500 mAh and can at least be with 30 Watt fast charging. With not even 440 is Euro the Poco-Phone the cheapest smartphone in this top 04. Android 11 already exists.

5th place: Oppo Find X2 This is the Oppo Find X2 not yet the case, but the rest of the equipment is convincing. This includes about the 6.5 inch OLED display with 90 Hz, the Quad-Cam with main, telephoto and wide-angle camera (48, 8 and 5 megapixels) plus macro camera with 5 megapixels and the built-in Snapdragon 765G. It doesn’t come close to the performance of a Snapdragon 865 do it but still a good figure in everyday life – also because he is proud 12 GByte RAM is combined.

Even with the internal memory, the manufacturer doesn’t do things by halves, but builds 256 GByte a. 5G is on board. The battery appears with 4025 mAh comparatively small in size, but should not cause any problems in everyday life. It can be described with 30 load watt. Android 11 does not exist yet.

6th place: Oneplus Nord This also applies to the Oneplus Nord ( Test report), with the the manufacturer back to its roots again oriented and great technology at a comparatively manageable price brings . Compared to the earlier “flagship killers”, however, this no longer works in all respects with top technology. The upscale mid-range device offers a decent OLED display with 90 – Hertz playback, but “only” a Snapdragon serves as the drive 765G. However, since the large configuration of full 11 GByte RAM and 200 GByte of internal memory is flanked, this should hardly bother anyone in everyday life.

In the actually good 48 – Megapixel camera, the manufacturer unnecessarily uses an additional macro camera with only 2 megapixels instead of telephoto function. The front camera with 32 Mega p ixel also has a second wide-angle lens. When it comes to endurance, the modern chipset has a positive effect, the battery with 4025 mAh ensures long running times. Together with the chic and high-quality housing, the North is a successful all-round carefree Package.

7th place: Oppo Reno 4 5G Oppo sets the Reno 4 5G to a 6.4 Inch OLED display without a higher Hertz number. Die K amera consists of main lens and wide angle with 48 and 8 megapixels, plus a depth sensor. It is also available on the front, it supports the 32 – Megapixel selfie cam. Also Oppo uses the Snapdragon 765 G , combined in but with 8 GB of RAM. 128 GByte of internal memory are just as fine and 5G is also included. The 4000 – mAh battery can be quickly removed with 65 Charge watt. Android 11 is available for the Oppo -Model already.

Place 8: ZTE Axon 11 5G Not so with the ZTE Axon 11 5G, the remaining values are mostly correct. The manufacturer uses 60 -Hz-OLED , the Quad-Cam consists of 64 – and 8 -Megapixel lenses for main and wide-angle cameras. They are filled by the macro and depth sensors with 2 megapixels each. Name-giving 5G is on board as well as a Snapdragon 765G. The combination of 6 GB of RAM and 122 GByte of internal memory is in G As opposed to d s better placed models, it can even be expanded with a micro SD card. The battery is performing 4000 mAh , 18 – Watt charging is comparatively slow.

Place 9: TCL 10 Per 60 – Hz-OLED with 6.5 inches, Quad – Cam with main and wide-angle lens (60 and 16 megapixels) and the annoying pretty – components Macro and depth sensors are unfortunately still very common in this price range . The Snapdragon 765 (without G) does a decent job in combination with 6 GB. The internal 128 GByte memory can be used via Mi cro-SD – Map expand – in this top – 10 the exception. The battery with 4500 mAh can only be used with 18 Watt load. So far there is only Android 10.

Place 10: Apple iPhone SE (2020) Who doesn’t like Android and prefer to stand on smartphones with the bitten apple, get to 500 Euro on current devices only the iPhone SE (2020). It is a bit out of line with the comparatively weak hardware, but thanks to the optimally adapted iOS 14. 3 anything but slow – also thanks to the strong Apple-A 13 – Bionic- Chipset . Surprised for that the device with a small 4.7-inch display and only 1334 × 750 pixels and only 3 GByte R.A.M. The 128 GByte As always with Apple, internal storage cannot be expanded, 5G does not exist. 1821 mAh with the battery sound almost negligible .

Conclusion Remarkable what one is for under 440 Euros in technology. The difference to the absolute top is sometimes not that great, at least not when you compare the price to the added value. Otherwise, the latest top models from established manufacturers are of course even better – anything else would be strange.

Anyone who doesn’t 500 want to spend euros, should take a look at our guide: The best smartphones up to 400 Euro, purchase advice: Smartphones with OLED up to 300 Euro and our best list : Top-10 of smartphones up to 200 Throw euros. Even in the last category there are amazingly strong devices.
