So my phone sometimes, more recently on boot, acts as if I held the power button and soft resets. Then, it turns off and wont turn on, if I plug it in, a red flashing light appears and eventually the battery percent screen comes up and I can restart it, after taking abnormally long to boot. It then proceeds to turn itself off again. What can I do?
Welcome to Android Central! It's likely a hardware issue -- perhaps a faulty Power button, or worse yet, a failing motherboard. At this point, the best you can do is bring it to a repair shop. Since this is a red flag that the phone may be failing, make sure all of your important data is backed up or synced.
