Vivo X20 Plus UD with under-display fingerprint reader is now official

Kickstarting a new trend for 2018

The phone showcased during CES 2018

We first saw Vivo’s phone with an under-display fingerprint reader a couple of weeks ago at CES 2018 as a demo phone. It didn’t take too long for the Chinese company to officially announce the device, and it’s now known as the X20 Plus UD.

The Vivo X20 Plus UD is the world’s first smartphone to ship with a fingerprint scanner built under its display. The handset’s physical design and specifications are identical to the commercially available Vivo X20 Plus in China, albeit with a under-display reader — hence the “UD” moniker.

It’s got a 6.43-inch near-borderless display which has a Full HD+ resolution (2160 x 1080 pixels). The Clear ID 9500 fingerprint sensor from Synaptics is neatly tucked near the bottom edge where phones usually had their fingerprint readers. It has an AMOLED panel as a requirement for the sensor to work.

As for the rest of the specifications, we have a Snapdragon 660 processor onboard with 4GB of memory and a whopping 128GB of internal storage. If that ain’t enough, a hybrid microSD card slot is always ready for action.

Keeping in with the trend, the X20 Plus UD also has two rear cameras — the main one having а 12-megapixel sensor and a f/1.8 lens, while the secondary has 5 megapixels. It comes with a 12-megapixel front camera for taking selfies.

The battery capacity of the phone is pretty hefty at 3905mAh which is more than enough to power it through the whole day and charges through USB-C. And since it’s from Vivo, the phone has a built-in ES9318 DAC for Hi-Fi audio — something the company is known for ever since.

Vivo pointed out that screen protectors will not get in the way of the under-display reader as long as they don’t exceed a certain thickness; otherwise, they would affect the reflection of light from the OLED panel and confuse the sensor. The phone will come with a layer of film that works out of the box to save buyers the time of finding a compatible one.

The phone will officially be available starting February 1 with a price tag of CNY 3,598 (US$ 565) in China. There are no available color options aside from black with golden rims around the display and cameras on the back.

Call of Duty drops the PlayStation 4 starting with its next game

Is this the beginning of the end for the PlayStation 4?

When can we declare that a console is officially dead? Is it as soon as the launch of the next generation? Is it when games no longer come out on the console? Recently, Call of Duty has confirmed that the next game will not be available anymore on the PlayStation 4, which presents an important question: Is the PlayStation 4 officially dead?

Call of Duty is one of the most persistent gaming franchises today. The last entry, Black Ops 7, is still available for the PlayStation 4 and the Xbox One. Both consoles were launched over twelve years ago. (If that doesn’t make you old, the current generation was launched almost six years ago.)

As such, the franchise is one of the last stalwarts keeping the past generation alive. This week, Call of Duty, via a post on X, confirmed that the next game will not arrive on the PlayStation 4. Presumably, this also means the Xbox One.

Currently, we don’t have details about the upcoming game yet. But a new entry is confirmed to arrive later this year.

With the departure of the Call of Duty franchise, it’s fair to ask what will become of the old generation moving forward. Over the years, developers have started shying away from the PlayStation 4 and the Xbox One. Since the franchise still maintains a steady fan base today, a lot of PlayStation 4 users might be forced to make an upgrade to play the latest entry.

TCL CSOT Unveils ‘APEX Pixel’ innovations at SID Display Week 2026

Breakthroughs in display technologies

Pushing the boundaries of display physics, TCL CSOT has officially launched its APEX Pixel framework at SID Display Week 2026.

This unified innovation path targets the microscopic architecture of pixels across FMM OLED, Inkjet-printed (IJP) OLED, and LCD panels to redefine clarity, power efficiency, and color volume.

The Super Pixel revolution

The highlight of the showcase is the Super Pixel technology for mobile FMM OLEDs.

By increasing sub-pixel density by roughly 1.8%, TCL CSOT has achieved sharpness comparable to WQHD standards while slashing power consumption by 25%.

Key mobile prototypes on display include:

  • 6.9-inch Ultra-Clarity Display: Features a 2608×1200 resolution with a 0.5mm top bezel
  • 165Hz High-Refresh Panel: Utilizes a Real RGB layout to boost motion smoothness by 40% over standard 120Hz screens
  • Ultra-Low Power 8T LTPO: A 420PPI powerhouse that reduces SoC power draw by a quarter.

IJP OLED and the Tri-Fold Future

TCL CSOT continues to lead the transition toward Inkjet-printed (IJP) OLED.

By utilizing the world’s first 8.6-generation IJP line, the company has debuted a 28-inch Foldable and Portable IJP OLED Monitor.

This “Real Stripe” RGB display features a tri-fold design that expands from a 16-inch footprint to a 28-inch workspace.

IJP OLED allows for larger light-emitting areas, occupying 50% to 60% of the pixel. This leads to a significantly enhanced luminous efficiency compared to traditional evaporation methods.

RGBC: The New Standard for LCD

For large-scale cinema experiences, TCL CSOT introduced RGBC Four-Color Technology.

By adding a Cyan sub-pixel to the traditional RGB matrix, the 85-inch WHVA Ultra LCD TV achieves a staggering 131% of the BT.2020 color gamut.

This hardware-level shift allows for more saturated hues and finer resolution rendering that traditional three-color pixels cannot replicate.

Through APEX Pixel, TCL CSOT is no longer just chasing size, but perfecting the very atoms of the digital image.

iPhone 17 is the best-selling phone of 2026 so far

Meanwhile, the Galaxy S26 series didn’t make the top ten list.

With more than a quarter of the year done and dusted, it’s time to figure out which smartphone has taken the early lead in the charts. According to the numbers, it can’t get any clearer. The iPhone 17 is currently dominating the charts.

According to Counterpoint Research, the bestselling smartphone in the world as of the first quarter is the base iPhone 17. The model took 6 percent of the global share in unit sales. Meanwhile, the iPhone 17 Pro Max and Pro took the second and third spots, respectively. Only a bit surprisingly, Apple rounded out its quarter with the iPhone 16 taking the number 6 slot.

The stranger thing is Samsung’s presence on this list. The South Korean brand took five spots on the top 10 list. However, none of them are of the Galaxy S26 series. All of them are from the Galaxy A series: in order, Galaxy A07 4G, A17 5G, A56, A36, and A17 4G. (The Galaxy S26 series narrowly missed the top 10.)

That makes nine. The final spot was taken by the Xiaomi Redmi A5.

Going only by the last two paragraphs, you’ll likely assume that the midrange market is rightfully dominating the charts in the months following the Christmas season. However, the iPhone 17’s dominance confirms that Apple has not lost its stride.

Plus, with the iPhone 17e only just having launched, Apple might continue its run well into 2026.
