Redmi doesn’t remove fingerprint lock from their phone. They relocate the position of fingerprint lock from back to the screen.
Yes, I am right. After the design, Redmi Note 6 pro all contains front screen fingerprint lock. Further, It is inbuilt into the screen. If your phone is a lock, put your finger on below the middle surface of the screen, and it will unlock.
Upcoming Redmi phones like Note 7 Pro, Note 7S also K20 Pro all of them contains same screen display finger lock.
