My Xiaomi MI 4 doesnt go on 'sleep' automatically no matter whatever duration is set in the Settings->Additional Settings->Display section
:-) okay .. One of my friend has the same phone and when she receives a call from anyone the flash light turn on . so how to stop that ?? And there is no call setting I have already checked .
It's probably one of your apps running on the background. Think of the last app you installed before that started happening and uninstall it. Let me know if that's just it.
