Realme C12 gets a new version as C20 leaks extensively

The original 3GB/32GB variant of the Realme C12 introduced last August is just joined by a new memory version in India that has 4GB RAM and 64GB storage onboard.

Priced at INR9,999 ($135/€110), the new variant costs INR1,000 ($15/€11) more than the base model and is already up for purchase through Flipkart and Realme.com in Power Blue and Power Silver color options. It will also be sold through retail stores across the country starting January 20.

The Realme C12 is powered by the Helio G35 SoC, sports a 6.5″ HD+ LCD, and features a 13MP triple camera. The smartphone also comes with a rear-mounted fingerprint scanner and packs a 6,000 mAh battery that draws power through a microUSB port. You can head this way to check out the detailed specs of Realme C12.

While Realme’s Indian branch has launched a new C12 variant, its Vietnamese counterpart is preparing to announce the C20 soon as its promotional image has surfaced online.


Realme C20 has a lot in common with C11

The Realme C20 looks similar to the C11 and will come in at least two colors – Black and Blue. The smartphone will be powered by the Helio G35 SoC and will have 2GB RAM and 32GB storage onboard.

The C20 will pack a 6.5″ HD+ screen and feature a total of two cameras – a 5MP selfie shooter and an 8MP primary camera. Fueling the entire package will be a 5,000 mAh battery with 10W charging.

Flashback: the original Samsung Galaxy S was a best-seller that spawned an empire

We’ve covered the Galaxy S II and Galaxy S III in previous Flashback articles, but now it’s time for the original – the one that started it all. Well, ther was the I7500 Galaxy after which almost all of Samsung’s Android phones are named, but we mean the original S-series phone.

The Samsung Galaxy S (I9000 if you want to compare model numbers) was announced in March 2010. Yes, the S series are over a decade old now. The phone became available in June of that year and would reach a total of 10 million units sold by January 2011. 4 million of those were sold in North America (more on that later) and 2.5 million went to Europe.


Samsung I9000 Galaxy S

The S-phone popularized Samsung’s Super AMOLED panel, though it was not the first to use them. That honor goes to the Wave, a Bada-powered phone. Samsung hoped that the Wave series would sell millions of units too, the company was used to juggling multiple OSes. But Androids explosive growth quickly put an end to Bada, Symbian, Windows Mobile and other lines.

Back to the screen – it was a 4.0” panel with 480 x 800 px resolution, using the PenTile arrangement (two sub-pixels per pixel, not three). It was arguably the most impressive screen we had seen until then.


The Samsung I9000 Galaxy S compared with the iPhone and the LG BL40 Chocolate

The panel was laminated to the Gorilla Glass protective layer, so the image almost appeared to float on the top of the glass – most phones back then had an air gap between the screen and glass (sometimes plastic). Also, the contrast of AMOLED made the image pop, it had a clear advantage over the LCDs of the day.

At 9.9 mm thick, the Galaxy S was marketed as the thinnest Android smartphone in the world, a title that would be claimed by its successor, the S II, the following year.

The phone was powered by the Hummingbird S5PC110 chipset, later renamed Exynos 3 Single 3110. This was the first-ever Exynos chip and it was co-developed with Intrinsity, a company that specialized in high performance CPU design (Intrinsity was snatched up by Apple in 2010, shortly after the phone was announced).

The chipset featured a single-core Cortex-A8 CPU running at 1.0GHz (up to 1.4GHz in some variants). It was paired with 512MB of RAM and 8GB storage (with a 16GB option). Also, microSD cards up to 32GB were supported.

This was important as the Galaxy S was one of the best multimedia devices of its day. It was the first Android to be certified for DivX HD viewing (remember the DivX video codec?). Of course, the AMOLED display made for an awesome experience with its high contrast and saturated colors.

The phone also had a 3.5mm headphone jack with a Wolfson WM8994 DAC and, as we noted in our review, the audio quality was excellent.

The Galaxy S launched with Android 2.1 Eclair, which was skinned with TouchWiz 3.0. That’s right, version 3.0. Samsung started the TouchWiz project several years prior in an attempt to unify the touch interfaces of its phones that ran Windows Mobile, Symbian and even featurephone OSes (including the Jet and others). Like we said, at the time Samsung preferred not to be tied down to a single operating system.


The TouchWiz 3.0 user interface comes preinstalled on top of the Android OS

Anyway, the phone was officially updated to 2.3 Gingerbread. It never got 4.0 and later Androids with the official explanation being “not enough RAM”. However, with millions of units sold, this was a popular target for custom ROMs. If you take a peek at the XDA forums you’ll see some surprisingly recent posts. It seems that the latest version that you can get running on the I9000 is 7.1 Nougat.

The phone was equipped with 5MP camera on the back, which was pretty bare-bones. There was no LED flash, never mind a hardware shutter key. The photos it produced weren’t the best either (noisy and underexposed). On the plus side, the phone did record 720p video at 30 fps, which was no small feat back then. For comparison, the Samsung i8910 Omnia HD only got up to 24fps.

We promised more detail on the Galaxy S in the North American market and, oh boy, there’s a lot to cover. The I9000 served as a basis for all kinds of variations, it seems that every carrier wanted its own version of the phone. Some of these only switched up the supported 3G band bands to fit the carrier’s network.

Then there were the likes of i897 Captivate for AT&T and later the i927 Captivate Glide, which packed a slide-out QWERTY keyboard. Or the I997 Infuse 4G also for AT&T. Note: it’s a 3G phone, never mind the deceptive marketing. The same goes for the Galaxy S 4G T959 for T-Mobile (aka Vibrant). It was a weird period in time when carriers started calling HSPA+ “4G” (they did much the same with LTE-A and “5G”).

The Epic 4G for Sprint was also a 3G phone, though the CDMA kind of 3G this time (this version had a keyboard). Verizon and US Cellular received CDMA versions as well, e.g. the Fascinate and Mesmerize i500. Samsung did create some honest to goodness 4G (LTE) models in 2011, ones like the Droid Charge I510 and I405 Stratosphere for Verizon – the former out a keyboard, the latter with.

It’s not just LTE, the Droid Charge also borrowed the larger 4.3” Super AMOLED Plus display of the Galaxy S II (which had a full RGB stripe instead of a PenTile matrix). Also, the camera was upgraded to 8MP, though the phone kept the original Exynos chip so no 1080p video recording.

We’ll quickly go over a few other notable variations of the Galaxy S. On one end of the spectrum was the I9003 Galaxy SL. The goal with this one was to create a low-cost version of the highly popular device. This led Samsung to switch the display to an SC-LCD panel and the chipset to a TI OMAP 3630. Also, RAM and storage capacities were reduced.

On another end was the I9001 Galaxy S Plus, a fancier version of the phone (though not as good as the Charge). This one kept the Super AMOLED display and got an upgraded chipset – a Snapdragon S2 with a 1.4 GHz Scorpion core and Adreno 205 graphics (replacing the PowerVR SGX540 GPU). Performance was a mixed bag (check out the benchmarks in our review) with Snapdragon’s CPU being much faster, while its GPU lagged significantly behind.


Samsung I9001 Galaxy S Plus

Earlier this week Samsung launched the Galaxy S21 series, the 12th generation of S-phones. They still use Super AMOLED displays and (some of them) are powered by Exynos chipsets, though both are much improved from what was back then. No more TouchWiz, though, that was supplanted by One UI (and for the better, many would say).

Alienware AW2521H 360Hz Monitor Review: Motion Blur Be Gone

Our Verdict

Though priced at the premium level, the Alienware AW2521H delivers something almost no other monitor can: 360 Hz with a 3 ms screen draw time. That means there’s no motion blur, period. If you have an equally premium gaming PC to go with it, you can’t get better performance from any other display that doesn’t run at 360 Hz.

For

  • Fastest refresh rate you can get
  • Nvidia Reflex performance analyzer
  • Excellent HDR
  • AlienFX RGB
  • Low input lag
  • Usable ULMB

Against

  • Average SDR contrast
  • No FreeSync
  • Expensive

Features and Specifications

Is the best gaming monitor about resolution, color saturation, contrast or speed? If you picked speed, then a 360 Hz monitor is for you. The 360 Hz refresh rate is the current pinnacle of smooth response and the lowest available input lag.

LCD technology has spent its entire life working to overcome one major flaw, motion blur. Because each frame remains on the screen while the next one is drawn, it has been termed “sample and hold.” Self-illuminant panels, like plasma and OLED, redraw the image hundreds of times per refresh cycle, which means there is no blur, even at frame rates as low as 60 fps.

LCD has two ways to combat this, higher refresh rates and backlight strobing. Better known as ULMB (ultra low motion blur), backlight strobing inserts black frames in order to mimic the action of OLED and plasma. It is effective but it reduces brightness and, in most cases, prevents the use of FreeSync or G-Sync. The better option is to raise the refresh rate and that’s exactly what the Alienware AW2521H does. Running at 360 Hz, it not only eliminates motion blur, it delivers super low input lag.

Fast flat panels used to rely on TN technology for their speed, but that is no more. Now, we have fast IPS, which brings back good viewing angles and better color saturation. The AW2521H uses one of these, along with a white LED edge-array backlight. HDR10 signals are supported with an effective dynamic contrast feature that broadens dynamic range to almost 8000:1 for HDR using a variable backlight option.

Video processing is cutting edge, of course, with 360 Hz and G-Sync. There is no FreeSync support, which is a bit unusual in today’s market. The AW2521H also includes ULMB up to 240 Hz. It won’t work in concert with G-Sync but does make a visible difference in motion resolution. Alienware makes a 240 Hz FreeSync version of this monitor, the AW2521HF.

Assembly and Accessories of Alienware AW2521H

You’ll notice the gold-plated contacts in the stand when snapping it onto the panel. That enables the lighting. You can still use an aftermarket arm with the included 100mm VESA mount if you wish. The cable bundle includes two DisplayPorts, one with a mini connector, and a USB 3.0 wire. The power supply is internal and fed by an IEC power cord. You also get a snap on cover to tidy up the input panel.

Because it is a premium monitor, we expect top-level build quality and a long feature list. The Alienware AW2521H has both. Not only is the AW2521H well-made, it has a glowing Alienware logo on the back and a long LED bar on the stand that mimics the shape seen on Alienware’s gaming PCs.

The AW2521H features the same small bezel look as most of today’s gaming monitors. The bezel is visible when the power’s on, but is only 7mm wide at the top and sides. The bottom trim is 15mm wide and features the Alienware logo and a label proudly announcing “360 Hz.” A tiny LED at the lower right glows white and doubles as the power button. Behind the right edge are four more keys and an on-screen display (OSD) joystick. They click like a high-end monitor should and make short work of menu navigation and control. On the panel’s top edge is an ambient light sensor. Turning it on allows the image to vary in brightness with your room’s lighting.

Styling is minimalist but distinctly Alienware. The long oval shape is a theme that appears on the back of the upright, ringed by LEDs. You’ll see the same element on an Alienware gaming PC which we currently have in the lab. The RGB is coordinated once you make a USB connection and is controllable in the OSD and by the Alienware Command Center app using AlienFX. You can set different colors and effects for particular games or just to your liking.

The stand is of high quality and offers a 5 inch height adjustment along with 20 degree swivel left and right, 5/21 degrees of tilt and a 90 degree portrait mode. Inside the upright, visible from the front, is a convenient graduated number scale so you can remember your height setting when moving the AW2521H from place to place.

The input panel is recessed deeply underneath, so much so that cables with large connectors will be difficult to use. Luckily, two of the USB ports and the headphone jack are under the panel edge in a more accessible position. Video inputs include two HDMI 2.0, limited to 240 Hz, and a DisplayPort 1.4, which is the one to use for G-Sync and 360 Hz (see our DisplayPort vs HDMI article for more). You also get two more USB 3.2 downstream ports and an upstream, for a total of one up and four down.

There’s a second 3.5mm jack for external audio but no internal speakers in the AW2521H.

OSD Features of Alienware AW2521H

The AW2521H’s OSD is extensive and features everything needed for performance-oriented gaming.

There are nine picture presets, mostly game-type specific, three gaming modes and Custom Color if you want to calibrate grayscale. The gaming modes allow changes to color saturation only and let you set different overdrive speeds depending on game type. Performance Tip: use the Fast overdrive setting for everything; it works the best.

Game Enhance mode includes a frame counter, countdown timers and multi-screen alignment marks but no aiming points. Response time is the overdrive control. Again, we suggest you use Fast for best results. Dark Stabilizer raises the black level to make shadow detail more visible. And Variable Backlight is an effective dynamic contrast feature. It has three modes, and Mode 0 is the most responsive. Each higher level delivers the same dynamic range but at a slower rate of change.

The AlienFX Lighting menu lets you change color, brightness and effect for the upright and panel’s LEDs. You can also create custom scenarios linked to specific games in the Alienware Command Center app.

The G-Sync Processor menu accesses the Nvidia Reflex Latency Analyzer, which shows control lag in real time in an on-screen window. It requires a USB connection and that you plug your mouse into the special USB port on the panel’s bottom edge.

ULMB is the backlight strobe feature that reduces motion blur. You’ll have to turn off G-Sync and reduce the refresh rate to 240 Hz to use it. It automatically sets the brightness to 100% to compensate for the loss in light output. Equalizing the brightness setting showed us a 12% reduction when starting at 200 nits. But if you max the backlight with G-Sync, it’s 48% dimmer with ULMB, so the change isn’t constant. With independent brightness settings though, it’s easy to equalize the output level, as long as you don’t want more than 238 nits.

Alienware AW2521H Calibration Settings

There are two ways to calibrate the AW2521H. In the three Game modes, color saturation controls are available, but there are no gamma or grayscale adjustments. The better choice is Custom color, where there are RGB sliders but no gamma options. We achieved accurate color with this option for both SDR and HDR content. Our recommended settings are below.

Picture Mode Custom Color
Brightness 200 nits 73
Brightness 120 nits 37
Brightness 100 nits 29
Brightness 80 nits 20
Brightness 50 nits 7 (min. 39 nits)
Contrast 75
Color Temp User Red 100, Green 99, Blue 90

When an HDR10 signal is detected, the AW2521H switches over automatically. You can still adjust the RGB sliders in Custom Color mode, but we were able to use our SDR settings for HDR.

Gaming & Hands-on with Alienware AW2521H

The AW2521H also includes Nvidia’s Reflex performance analyzer that shows real time information on screen with input lag and frame rates and is said to help reduce input latency (for more see Nvidia Reflex tested).

Though its focus is premium gaming, the AW2521H is a decent all-around monitor for everyday use. At 25 inches, its 1080p resolution provides enough pixel density to render small fonts and fine details well. An extra bit of sRGB gamut volume means bright and vibrant color for photo editing or video watching. The IPS screen provides decent viewing angles with little color shift or light reduction when viewed up to 45 degrees off center.

We engaged the variable backlight feature on Mode 0 for a little extra SDR contrast. Black levels aren’t all that deep, so shadow areas looked more like dark gray. It’s not that different than typical IPS screens in this regard.

Quickly we noticed how smooth any kind of motion looked. 360 Hz is seriously fast, and even just moving dialog boxes around the desktop looked almost other-worldly. Indeed, the difference between 240 Hz and 360 Hz can be seen with casual observation.

ULMB reduces brightness by around 12% if you start at 200 nits. Brightness can be raised to compensate. It only works up to 240 Hz, but it really makes a visible improvement to motion resolution. We thought there was no blur when watching BlurBusters test patterns at 360 Hz, but engaging ULMB at 240 Hz made it look even smoother. That means that if you don’t care about G-Sync, it’s actually better to do 240 Hz with ULMB than 360 Hz. It’s a shame ULMB can’t be used with G-Sync. But at 240 fps, tearing is barely noticeable, so some users might prefer to use ULMB.

For SDR gaming, we played a few hours of Tomb Raider. We left the variable backlight on Mode 0, which upped contrast slightly. Color was rich and saturated with natural hues, but shadows were still more gray than black. The AW2521H is reasonably accurate without calibration but our adjustments  (see our calibration settings on page 1) are well worth doing, since they make a visible improvement.

Motion processing is simply the best there around. However, we saw no advantage to the AW2521H over the Asus ROG Swift PG259QN 360Hz monitor. Overall, response is on another level, and motion clarity is superior to any 240 Hz screen we’ve encountered. G-Sync worked perfectly as we often hit the 360 Hz maximum, thanks to the GeForce RTX 3090 graphics card in our Alienware gaming PC.

We enjoyed the same experience in Call of Duty WWII, which definitely looked better with HDR engaged. There was more pop and sharper detail in both highlight and shadow areas of the image. HDR processing cost us about 20 fps, but the game still hit 360 fps on occasion. Playing at 300 fps most of the time was no burden. Gameplay this responsive and smooth is truly addictive.
