Last year we talked about Synaptics, a company developing an in-display fingerprint scanner for an Android mobile phone from a major mobile brand.
Since then, it was revealed at CES 2018 that Chinese smartphone manufacturer Vivo was their launch partner. The in-display fingerprint reader is being launched as a major feature on their Vivo X20 Plus UD model which is now available for pre-order in China.
The phone features a 6.43-inch Full HD+ (2160×1080) 18:9 AMOLED panel with an edge-to-edge design. The fingerprint sensor is placed on the front on the lower portion of the display screen. When the user’s finger is placed on the designated area, light is emitted through the screen’s AMOLED pixels to read and validate the fingerprint, a task not achievable with an LCD screen.
Unlike the facial or other thumb print readers available on devices like the iPhone or more popular Android devices, the phone takes a bit longer to validate the fingerprint, but from tests at the recent CES convention, it does seem to work pretty well.
Besides that feature, the phone itself is the same otherwise when compared to the Vivo X20 Plus. It features an octacore Snapdragon 660 processor, 4GB RAM and 64GB of internal storage space, and has dual SIM trays. There is also a slot for external microSD cards which can facilitate up to an extra 256GB of storage.
It also has a 3905mAh battery and a 12MP rear facing and 5MP front facing camera. Unfortunately it is running Android 7.1 out of the box even though Android 8.x have already been out for a few months now.
Back when the iPhone X was being designed, Apple initially wanted to implement similar in-display fingerprint recognition technology as the phone featured a complete edge-to-edge display, but faced technological issues and opted to develop a facial recognition system instead.
Vivo has basically brought out a game changing feature, and I would not be surprised if it puts more pressure on big names like Samsung, Apple, HTC, and LG to follow suit when they release their next flagship devices.
The Vivo X20 Plus UD is currently on sale in China only via pre-order for ¥3598 or about US $569.
