    My OnePlus 8t is turning off randomly. A few days ago just when I was locking the screen. Today it turned off when I was working on it.
    It doesn't have a rule. It's just turning off.

    It's a very big problem.

    Usually this is a cause of an app causing the phone to reboot. Much like a bluescreen on windows. Try booting into safe mode and see if it happens there.

    Usually it's the one you're active in at the moment. But if it's hard to find --> back up, and reset your device.

    Do you know how to reset to erase all updates? I think it's from an update.

    You can downgrade, but you'll need to factory reset either way for that. So I suggest trying that first.

    Hello everyone ones.
    I still didn't find the problem.
    Can it be from sim card? It lost few times the signal. But the sim card is working perfectly on my old OnePlus 5t.

    Hello.
    Founded the problem.
    It comes from Gmail with 2 ore more accounts.
    Deleted Gmail and turned off updates.
