I went to use my phone and noticed it was off. I turned it back on my phone was on 76% so there's no reason my phone should have been off. I turned it on unlocked it and waited a few minutes for it to load picked it back up and yet it was off again. I got to watching it and I can lock my phone or turn screen off it doesn't turn off but when screen times out a light flashes at top like I have a message I go to unlock my phone but nothing happens it's like it shut its self off can some one please help me figure out how to fix my phone.
Do you experience these symptoms if you test your device in safe mode?
If your phone is misbehaving, it's possible that a third-party app is causing the issue. To figure out what app is acting funny, you can use the Safe Mode feature. In Safe Mode, your phone won't run any third-party apps. This allows you to easily identity and remove the app that may be causing the problem.
