Hi guys I have a mi4c for quite a while, and lately it has been starting to reboot everytime the screen is off I set screen to never turn off, and it would not reboot until battery does or screen was off. So i figured it must be a sleep issue. So i upgraded to miui to latest eu rom 8.1.18 And still, everytime screen went off it rebooted. When i left screen on even without any activity it would stay on no problem. Did anyone had this problem? Any solution?
