The Xiaomi Redmi Note 5 Pro is the first smartphone launched in India from Xiaomi with support for Face Unlock. The Face Unlock on the most of the Android phones is achieved using the front-facing camera, unlike the iPhone X, which uses a dedicated array of sensors to enable true depth scanning.
How to enable Face Unlock?
To enable Face Unlock on the Xiaomi Redmi Note 5, the smartphone should be running on MIUI 10 Global Beta version (v 10.8.8.2 or newer). Go to settings > Lock screen and password > Manage face data to enable Face Unlock. However, unlike a fingerprint sensor, a user can only register one trusted face at a time.
Do note that the Face Unlock on most of the smartphones will not be as secure as Fingerprint sensor. The Face Unlock will not work properly low lighting condition and cannot be used to authenticate payment apps.
This means devices like the Xiaomi Redmi Note 4 (which also runs on Qualcomm Snapdragon 625) and the Xiaomi Redmi Note 3 might also support Face Unlock with the future software updates.
