Hello, This is my first post. I need some help with my phone. Recently i've been having issues with my phone turning off on its self. I have tried back up and reset but it didn't work. This issue seems started after updating to 4.3 jellybean. Does anyone have any idea what might be causing this. Also after the phone turns off the buttons have no effect, the only way to "fix" it ( for 3-4 days) is by removing the battery and placing it back agian. Can anyone help me with this issues. Thank you, Fori.
