Hi all,

I have an issue with a Mi4c: The device boots normally, lock screen appears, I can swipe to enter pin but then it turns black instantly again. I have to hit the power button twice to get back into lock screen. Swiping left to access camera also turns the screen black immediatly. Sometimes when I try to unlock I see the unlocked homescreen (or parts of it) for a split second before it goes dark. When in lock screen, I can access the quick settings from notification bar normally. When I try calling while in sleep mode, it rings but doesn't wake up the screen so i can't receive the call. When calling while in lock screeen, it rings and goes black instantly.

I got my Mi4c from ******* last November. It still runs on the rom it came with which is some sort of global rom with locked bootloader, google services and english language pre installed as well as some basic apps which cannot be uninstalled. I'm not sure what version it is and since I can't access my phone I don't know how to find out.

I did some googeling on the issue with no real results. It would be much appreciated if somebody here had an idea.

Thx
EJ

The issue resolved itself after leaving the device turned off for a day. I'm still curious what caused it, though, and obviously i'd like to prevent it from happening again.
