Today, Living y Xiaomi are the two manufacturers that offer a fingerprint sensor under the screen. Both use Synaptics' Clear ID design, but that of the Xiaomi Mi 8 Explorer is faster than that of the Vivo X21. Why? We explain it to you.
The common ground: the Clear ID sensor is the same on both devices
El Clear ID sensor FS9500 is the one that we can find in devices such as the Vivo X21 or the Xiaomi Mi 8 Explorer. This sensor depends on the device having an OLED screen, since it works optically. This means that it throws light across the screen, bounces off the finger, and returns with the necessary information. So far it is the only method available in the world of mobile telephony to achieve a truly effective fingerprint sensor under the screen.

Pressure sensor: this is the advantage of the Xiaomi Mi 8 Explorer
If they have the same sensor, why is the Xiaomi Mi 8 Explorer faster? Because Xiaomi has decided to include a pressure sensor additional. The idea is that as soon as the mobile detects that a finger presses the screen, the sensor wakes up and starts to act, instead of waiting for it to be activated by continuously throwing light.
With this method, the fingerprint sensor Xiaomi it is more efficient and faster. This gives you an advantage against direct rivals and solves utility problems without having to resort to different methods. This has allowed the Chinese company to get ahead of Samsung. However, Xiaomi's sensor is still confined to a single area, and that is where Living it can turn the tables again.
Half screen fingerprint sensor: the Vivo Apex will lead the way
The future of Android may be marked by the success or failure of the next Vivo Apex. The device will stand out not only for its frameless design and its camera pop-up retractable, but also because the entire lower half of your screen will be a fingerprint sensor. In this sense, even if its sensor were still somewhat slower, it would be much more attractive than Xiaomi's, since in any area you could place your finger to detect the fingerprint and turn on the screen. A very noticeable usability improvement that would help Living to take the lead.
