The first phone with an under-glass fingerprint sensor officially announced

Update (01/24): vivo has officially announced the first phone with an under-glass fingerprint sensor.

The vivo X20 Plus UD, as mentioned in the original article below, is simply a variant of original X20 Plus without the rear-facing fingerprint sensor. Instead, vivo has partnered with US-based sensor maker Synaptics to include an under-glass fingerprint sensor in the front of the phone. We were able to try it out at CES 2018, which you can see in the video below:

The X20 Plus UD features a big 6.43-inch, 18:9 Super OLED display with a resolution of 2,160 x 1,140. It also comes with dual 12 MP cameras, a Qualcomm Snapdragon 660 SoC, and a 3,905 mAh battery.

Unfortunately this device is only being released in China for now. Pre-orders open today, though no pricing details have been announced at this time.

Original article (01/22): One of the highlights of CES 2018 was the announcement of the first smartphone to feature an in-screen fingerprint reader. CES ended only ten days ago, but Vivo has just announced that the first phone to hit the market with the new technology will launch on January 24.

Surprisingly, the phone will be sold as an X20 Plus. You might be confused by the moniker since the original X20 Plus launched in September 2017. In fact, the prototype featured at CES was a heavily modified X20 Plus. It appears that this new device will be a variant of the original, which could be confusing from a marketing perspective.

While no specs for this new X20 Plus were officially released, the telecommunications certification center of China (TENAA) lists the device with the following:

• 6.43-inch OLED display, 2,160 x 1,080 resolution
• 165.2 x 80.02 x 7.35 mm dimensions and 183.1 g weight
• 2.2 GHz octa-core processor
• 4 GB RAM
• Dual cameras on back (12 MP and 5 MP)
• 12 MP front-facing camera
• 128 GB memory, expandable via microSD slot
• 3,800 mAh battery
• Color choices including Black Gold, Champagne Gold, Rose Gold, & Matte Black

The TENAA listing all but confirms these specs to be true, but no one knows for certain until vivo launches the device in two days.

The rumored price of the smartphone is 3,998 yuan (USD $624.27). With the rumored specs listed above and the fact that the device is the premiere of one of the most highly desired features today, the X20 Plus easily falls into flagship, high-end category of smartphones.
