The Mi 8 Explorer Edition (EE) is the first Xiaomi phone to come with an in-display fingerprint scanner. It is also the first smartphone in the world to use a pressure sensitive in-display fingerprint scanner. Reports have revealed that the scanner is Synaptics Clear ID FS9500.
The Clear ID FS9500 was announced in December by Synaptics Inc. When it was announced, it was reported that Synaptics was working with one of the top five smartphone manufacturers. Synaptics itself later revealed that it was shipping the scanners to Vivo. That scanner is what is used in the Vivo X21 UD.
Although Vivo is the first manufacturer in the world to release a phone with an in-display fingerprint scanner, Xiaomi’s Mi 8 EE has an edge over it. Apart from the Synaptics scanner, it also has a dedicated pressure-sensitive sensor that makes unlocking faster.
The sensor has a high sensitivity that immediately detects when the finger is placed on the display and “wakes the main scanner up”. This allows the Mi 8 EE unlock faster than the Vivo X21 UD even though they both use Synaptics Clear ID FS9500 sensor.

The Mi 8 Explorer Edition not only has a faster scanner, it is also the first Android phone with 3D face unlock. This is more secure than that found in other Android phones.
