Garmin Edge 830 cycling computer review: Hitting the data sweet spot

(Pocket-lint) – Ask any cyclist what the first thing you should update on a bike is and they will invariably say the wheels. While that’s likely to give you the biggest performance upgrades, it’s hard to quantify that without the humblest of bicycle accessories, the bike computer.

Being of techy mind and body, we’d say that a bike computer is probably one of the first places you want to look to boost your riding experience, and Garmin has long been the leader of the pack. So how does the upper-level Garmin Edge 830 perform?

Design, build and mounting

  • 2.6-inch colour touchscreen, 246 x 322 pixels
  • Dimensions: 50 x 82 x 20mm / Weight: 79.1g
  • Varied mounting options in the box
  • IPX7 water protection

In terms of functionality, the Edge 830 is Garmin’s second-tier device, sitting under the Edge 1030 Plus and above the 530. The 530 is closely related – the biggest difference being the addition of touchscreen controls that you get on the 830 – but the design is essentially the same.

The Edge 830 isn’t the most compact thing around, but the bodywork is all there to support the 2.6-inch display as your visual gateway into a world of data and mapping.

Pocket-lint

The design is robust enough, with IPX7 protection, which means it won’t be bothered by rain showers or a soaking when you hit a big puddle. The waterproofing should mean it can withstand complete submersion in water, but that might dampen your ride a little. Having been caught in downpours and some winter floods, the odd soaking certainly doesn’t hamper this device’s performance – you don’t even need to think about it, as you might with an adapted smartphone in a holder.

The 830’s bodywork is a substantial polycarbonate with the front dominated by the display, but still carrying what a smartphone fan would class as bezel. We don’t think the Edge 830 necessarily needs to be smaller, but we do think that in future versions Garmin might aim to either fill more of the surface with display, or reduce that slightly for a more modern look.

The display is colour and while the resolution isn’t high by smartphone standards, it’s good enough to show the details you need. It’s an LCD, illuminated so you can see it easily, dimming in lower light conditions and powering off to save battery life if you use the power saving feature.

Pocket-lint

The body carries a power button on the left side, start/pause recording and lap buttons on the bottom, with a central cover opening up to reveal the Micro-USB connection that’s used for charging (USB-C and wireless charging next time please, let’s bring this kit up to date). The buttons mean you can use the device whatever gloves you’re wearing, although much of the interaction relies on the touchscreen.

There’s a twist mount on the rear of the Edge 830 with a number of mounts provided in the box, from handlebar or step mounts secured with the supplied bands, through to the out-front mount, which means you can move the computer out from your handlebars, which we find a better position for glancing when on the go – plus it means it’s not fighting against other handlebar-mounted devices.

The out-front mount has the advantage of allowing easy installation of the Charge Power Pack, which can clip onto the underside to extend the computer’s life by an additional 24 hours. As it is, the battery offers a realistic 15-20 hours of life, extending if you opt for the power saving mode that turns the display off (you can get it to communicate with a compatible smartwatch for at-a-glance views if you wish).

Pocket-lint

Installation is quick and easy, while removing the Edge is simply a case of twisting to release it. It can’t be locked in any way, but the Edge 830 supports Garmin’s alarm function, whereby you will get a notification if your bike is moved while you’re away from it – perhaps in a café, for example.

Connectivity, setup and Garmin Connect

  • ANT+
  • BLE/Bluetooth
  • Wi-Fi

The biggest part of setup for the Edge 830 is connecting it to the wider world. The first aspect of this is smartphone connectivity and pairing with Garmin Connect is relatively straightforward. If you’re already a Garmin user – perhaps with a Forerunner for example – you have the advantage of being able to use the Physio TrueUp function to sync across devices so your efforts on one device are reflected in your stats on the other.

Garmin Connect plays a central part here, of course, and once connected to your phone, your details from Garmin Connect will sync to your Edge. If you’re new to Garmin, it’s highly recommended that you setup Garmin Connect in advance of linking to your devices, just to make everything smoother.

Pocket-lint

It would be nice to have more customisation through Garmin Connect. As it is, if you want to change the content on the display, you have to set that on the Edge device itself – it would be far slicker if that could be organised in Garmin Connect and synced to the bike computer instead.

The connection with your phone gives the advantage of not only syncing rides and data once you’re done, but allowing smart functions on your ride – like Livetrack via your phone’s data connection (so others can follow your live route, if you permit), notifications and, in some cases, quick replies to those incoming messages so you can keep in touch with people without reaching for your phone (note: this is only available to Android users).

The connection is generally solid, although we’ve had a few occasions where we’ve set out, seen Livetrack fail and had to stop to ensure that the phone and Edge 830 are properly connected before setting off again.

Garmin does get a little confused if you change your phone, in which case the fastest way to connect with the device is remove it from Garmin Connect and then treat it like a new device and re-pair it. As long as you don’t reset your Edge it will then just connect to your device, sync and carry on as normal.

Pocket-lint

On top of the Bluetooth connection that the Edge would use with your phone, there’s also Wi-Fi. This means that the Edge 830 can connect to your home Wi-Fi network to update without your phone doing everything. This will again let you sync data, as well as downloading routes.

More significant to its actual function, however, is the ability to sync with additional sensors. While the Edge 830 offers GPS, an altimeter and accelerometer which will provide most of the essential data, there’s support for Bluetooth and ANT+ sensors. This will mean you can use compatible sensors to provide more data, like heart rate, cadence or power – all of which are easily accommodated on the display of the device, and in the subsequent data analysis.

Mapping and routing

  • GPS
  • Cycling-specific basemaps
  • Route syncing, rerouting

While much of the data you might want from a bike computer would be available from something like the Garmin Edge 130 Plus – which is a lot less cash – the advantage that something like the Edge 830 offers is in the route guidance and mapping. The device contains cycling-specific route maps, allowing on-device navigation and browsing.

You can, for example, open up the map on the device, find a place you want to go to and have it plot a route to get you there. It’s a little slow and you don’t get to preview or customise that route, but at least it’s there.

Pocket-lint

Navigation of the map when browsing is pretty good – you can drag it around and use the familiar pinch-to-zoom to adjust, but you lose the pinch zooming when you are actually following a navigation route. This makes it much harder to look around the map if you take a wrong turn or hit, for example, a closed gate on a private estate that the Garmin is trying to take you through.

Routes can be created or imported to Garmin Connect to sync to the Edge 830 too, as well as syncing from other apps, like Strava (although only the browser version of Strava currently makes this easy to do). Creating a route in Garmin Connect is easy, either creating an automated route in a particular direction for a given distance, or to somewhere specific you want to go.

Generally speaking it all works well, but we’ve found some anomalies – diverting you to an impractical cycle route over the main road that you’re on, routes through gates that are closed, some unpaved forest routes which don’t suit a road bike, and so on. Essentially, you need to be prepared to take a diversion, which is, again, why the lack of pinch-to-zoom during navigation is irritating.

Pocket-lint

Diversions and rerouting isn’t the fastest either. Often you’ll be asked to turn around repeatedly before you’ll eventually be given a new route – but it will find that route.

Overall mapping and directions is good, as is GPS, all on that glanceable big display so you can easily head out and explore. A top tip is to search for and save your home location, so you can easily sort out a return route if you decide you just need to get back home again.

Advanced features and functions

  • Training and workouts
  • Strava Segment support

Outside of routing and all that data collection there’s a lot more that the Edge 830 will offer. Part of the Garmin family, it will offer the sort of performance tracking and training guidance that Garmin’s running watches offer. That means you’ll get recommendations for your recovery time after a ride, the opportunity to log food or water consumption during a ride, and a report on what sort of training aims your ride achieved.

One element that’s slightly under-represented is Garmin’s Training Status. While those using Garmin’s running devices get a training status update from just a couple of runs, for cyclists you only get that if you have a power meter – and to calculate FTP (functional threshold power) you also have to ride with a power meter and heart rate sensor), so this is definitely a device that offers more as you add accessories.

Pocket-lint

You can structure workouts via your Edge, to ride indoors or outdoors, the former meaning you don’t have to worry about traffic on your intervals. The Edge 830 is compatible with smart trainers so you can pair your Wahoo Kickr with your Edge, for example.

There’s support for mountain biking, with integrated Trailforks routes so you can find something offroad to ride in your local area. There’s Strava integration too. Not only can you sync routes to the Edge, but you can setup Segments too.

This will let you compete against yourself or friends on Segments. That might spur you on to get a PB on a Segment, or be totally disheartened when you realise just how far off the pace you might be when you head out with a friend.

Pocket-lint

While Segments will give you a report of how far you have remaining and how far ahead or behind your target pace you are for a favourite stretch, Garmin will also give you guidance on climbs. This is automated, giving you the ClimbPro display when you hit a decent uphill stretch. It might help you balance your effort, showing how much further there is to climb.

What all this accounts to is a comprehensive offering for those who want to just ride, those who want data, as well as those who want to take things a little further.

Verdict

The Garmin Edge 830 is one of the most appealing in the Garmin cycling computer line-up. A slightly more affordable price than the leading Edge 1030 Plus, plus the touch functionality over the Edge 530, sees it sit in a sweet spot.

The performance is generally very good, too, but there’s clearly room for improvement in order to draw this bike computer closer to the excellent performance that people are used to from smartphones. Faster rerouting, better map navigation, an increase in display quality, and wireless charging, are all easy targets for Garmin’s product development team.

nida-rumelin:-germans-accept-location-with-the-corona-warning-app

Nida-Rümelin: Germans accept location with the Corona warning app

The Munich philosopher Julian Nida-Rümelin has underpinned his appeal to collect user location data via the Corona Warning App (CWA). Such tracking on smartphones would be the easiest way to be able to trace infection chains more easily in the fight against the coronavirus pandemic, he said on Thursday in an online debate in the authorities mirror . It is important to learn from the example of South Korea. There a tracking app is used for quarantine monitoring, not for tracking sources of infection.

According to Nida- Rümelins should make the location data collected via the CWA available to the health authorities in the event of a positive corona test. The person concerned put his smartphone there on the table and “they read it out”. This could also be made “pseudonymized, appropriately encrypted,” said the former Federal Government Commissioner for Culture. But it would be important to provide “traceability of identities”, “since there are also false-positive tests” and nobody should be sent into quarantine for free.

Acceptance will remain That the acceptance of the Corona app, which was previously based purely on tracing, with such a tracking process is falling , the vice chairman of the German Ethics Council does not believe. “Our user data, which we leave behind on various platforms, are used by tech giants almost at will for economic purposes and are controlled by the NSA,” he said. Many people knew this after the Snowden revelations, but did not change their behavior despite the associated dangers to privacy.

Most people kept the location services activated on their smartphones because it was convenient , explained Nida-Rümelin. For health protection purposes it would only have to be legitimate “that we give a few harmless incentives” for users to feed an upgraded CWA with their location data. He is sure that people will join in when they go to the hairdresser or restaurant or want to order an espresso on the ICE: “I’m not worried here at all.”

Already in one The draft bill from March for a reform of the Infection Protection Act was intended to allow the health authorities to track location data, argued the ethicist. A “legal consideration” has already taken place at least in the Federal Ministry of Health. This approach could therefore be used to identify contact persons for infected people. Health Minister Jens Spahn (CDU) quickly deleted the passage from the cabinet after protests.

Attendees the online debate of the authorities mirror.

Accelerate contact tracking Nida-Rümelin is nevertheless certain that everything must now be done to ensure that the offices are in place set to be able to digitally trace infection chains. Otherwise, there is a risk of a third or fourth lockdown in a few weeks if the numbers with contagions rise again. According to him, such tough measures are likely to cause many millions of deaths worldwide, for example through hunger. Data protection is very important, “but we also have to weigh this fundamental right with others”.

Overall, Nida-Rümelin was extremely concerned “that we in Europe are responding to the epidemic challenge with such helplessness to have”. If there wasn’t a vaccination, there would only be one shutdown after the next. South Korea, on the other hand, initially had the second highest infection rate after China, but “thanks to a very clever containment strategy in the end” it was just under 1000 Dead landed, “we at over 40. 000” in to 50 million inhabitants.

There is no tracking app in South Korea of infection chains that locate their users. The local health authorities proceed largely manually, but also rely on credit card data and videos from surveillance cameras. The quarantine app is mandatory, but will be deleted afterwards. She had a massive data leak at the end of July.

No question of data protection Anyone who says data protection prevents health is “talking nonsense”, countered the Thuringian data protection officer Lutz Hasse Nida-Rümelin. If the CWA were to be compulsory, this would not only have practical consequences, for example in terms of controllability. There would also be “an outcry across the country,” says the lawyer. A tracking app with GPS, the current location and other metadata is also likely to “run out of steam in our digital Middle Ages” because health authorities still work with paper and there is a lack of staff. In view of only “theoretical added value”, such a measure would be “currently meaningless”.

The chairman of the professional association of German laboratory doctors, Andreas Bobrowski, also warned against excessive zeal. The CWA is quite successful with millions of users and thousands of patients who shared positive infections almost daily. In principle, however, it is an “add-on to normal medical business”. On the basis of hundreds of phone calls with those who tested positive, it was found that “a lot of people know exactly where they got infected”, especially in their families or in old people’s and nursing homes. You could also pass this information on to the office.

No mandatory use “In spite of all its expressiveness, we do not want to ignore the relationship of trust and the need for data protection,” said Bobrowski in favor of maintaining a voluntary reporting system via the app. A few screws can still be turned, but there shouldn’t be any compulsory use.

At least in Schleswig-Holstein, by far the largest number of health authorities can now also communicate digitally with the laboratories, reported the Lübeck. There is also a dedicated laboratory app that can also be used to send the test result to the smartphone. The crucial time between the smear and the notification has become significantly shorter. The Sormas system for fast digital tracing did not fail either: Originally, all health authorities should be connected to 2023, now this is to create “a year earlier”. The federal and state governments have a more ambitious schedule: according to them, the program should now be installed nationwide by the end of February.

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.

Go read this report about the US military endangering passenger jets by blocking GPS

Mark Harris, writing for IEEE Spectrum, has come out with a chilling report about how military testing is leading to confusion among pilots — and sometimes putting them in danger. The piece goes into why the US military is jamming GPS in American airspace and recounts some of the times it’s almost gotten civilians killed. If you’re a frequent flyer or are interested in when military testing bleeds into everyday life, it’s well worth the read.

The military is carrying out the testing, ironically, to help develop technology to counteract GPS jamming. To be fair, it’s an understandable goal, as the article details the troubles that pilots face when a technology they heavily rely on goes away. But when that happens, the pilot at least has visual cues and other instruments. The article also goes into how, instead of completely cutting out the pilot’s GPS signal, the testing can end up feeding the pilot incorrect information, leading to thinking they’re somewhere they’re not.

Each tangent the article goes on reveals worrying new details, like how pilots are warned that testing may be happening, often leading to smooth flights and a “Chicken Little” situation where pilots have heard false warnings so many times that they’re not prepared for when it actually happens. There are also hints that the problem may be happening more often than even the Federal Aviation Administration realized.

It’s some necessary reporting. Without the public being aware of the problem, there won’t be any calls to stop or bring greater transparency to the testing. When the military carried out tests of nuclear bombs, it was at least obvious to people that something was happening, even if they were unaware of the radioactive particles (literally) raining down on them. Sometimes, pilots don’t even know that the military carries out GPS-jamming tests. So far, it doesn’t seem like the tests have killed anyone, but reading about the close calls described in the piece is harrowing, and it’s definitely worth your time.

The manufacturer PineMicrosystems presents another Community Edition of the PinePhone. The “PinePhone Community Edition: Mobian” can since 16. January can be pre-ordered in the Pine Shop and is available in two different hardware versions, one of which is also suitable for desktop use.

In a blog post Pine 64 gives an overview of the hardware specifications of the new PinePhone variant. In the basic version for 149 US dollars, 2 GB of RAM and a 16 GByte small eMMC module installed. The convergence package costs 199 US dollars, but comes with 3 GB of RAM, 32 GByte eMMC module and also contains a USB-C dock for the eponymous convergence mode. The dock has a Fast Ethernet port (10 / 100 Mbit / s), two USB ports (type A), an HDMI output and a USB-C port for power supply – the manufacturer does not specify version numbers.

Linux in small format Pine 64 delivers the new variant of the PinePhone with pre-installed Mobian. The operating system, designed for mobile devices, uses a patched mainline Linux kernel and uses Phosh as its user interface. Phosh is based on GTK program libraries and was originally developed by Purism for the Linux mobile phone Librem 5. The Mobian Community Edition follows the “UBports” -, “postmarketOS” -, “Manjaro” – and “KDE Community Edition”. Per unit sold there are 10 US dollars to the Mobian project to promote the development of mobile Linux systems.

Community who love to do handicrafts According to Pine 64 and the Mobian project, the core functions, such as telephony, SMS, 4G LTE, WLAN, Bluetooth, idle mode, run before and Rear camera and GPS. The Mobian installer allows you to set a username and password, as well as to configure encryption of the Mobian installation. Pine 64 advises buyers to use the Receipt of the phone to bring the system directly up to date. The delivered Mobian contains outdated software with known errors.

The new Mediatek Dimensity 1200 and Dimensity 1100 SoCs combine Cortex A78 cores at 6nm with 5G

Mediatek has renewed its high-end mobile processor with two new models of the Dimensity family, the Dimensity 1200 and Dimensity 1100. In both cases they are SoCs that integrate Cortex A cores 78 from ARM along with 5G connectivity.

It is manufactured to 6 nanometers and has support for high frequency displays. They will hit the market in the form of new terminals at the beginning of the second quarter of the year.

Mediatek Dimensity 1200 with display support of 168 Hz

The Dimensity 1200 leads Mediatek’s line of processors for smartphones, it is a SoC that combines the architecture ARM Cortex- A 78 together with the Cortex-A 55 in a distribution of three groups. The most powerful core is a Cortex-A 78 which is followed by a group of 3 cores also with Cortex A architecture 77 but at a slightly lower speed of 2.6 GHz. Finally, the last group of Cortex A 55 operates at 2 GHz of maximum speed for lower consumption tasks.

This SoC is accompanied by the Mali-G GPU 55 MC9 nine-core and supports LPDDR4x memory up to 4266 along with internal storage UFS 3.1. It is capable of handling FullHD screens up to 2. 520 x 1. 080 pixels along with a refresh rate of 168 Hz.

Naturally, it does not lack 5G connectivity with SA and NSA mode and Carrier Aggregation with which it is able to download data at 4.7 Gbps and upload it to 2.5 Gbps. For local connectivity we have WiFi 6 and Bluetooth 5.2, as well as a radio receiver, GPS, GLonass, Galileo and other location methods.

Mediatek Dimensity 1100 for displays of 144 Hz

The Dimensity 1100 will be the younger brother of 1200. It also combines Cortex A 78 and Cortex A 55 as architectures of its 8 cores, although in this case it only has two clusters or groups, one of four cores A 78 at 2.6 GHz and another 4-core A 55 at 2 GHz, losing that “premium” core at higher speeds.

The GPU is also a Mali G 77 9-core with which it can handle 2 screens. 520 x 1. 080 pixels, although this time the maximum refresh rate remains at 144 Hz

Maintains 5G multimode, WiFi 6 and BT 5.2 connectivity along with the rest of the options of its older brother.
