Hi, My Xiaomi MI2 on 2.12.7 has a tendency to stop functioning properly while trying to unlock, happens once every 10 times. It won't go out of the lockscreen while i slide it to the unlock area, instead it refuses to stay on the area i slided to, just goes back to the middle, no matter how many times i try. I have to shut off the screen again, turn it on again and then it works fine. Any help please? Thanks in advance!
