Yesterday my phone turned off, and it didn't come back on. After pressing the rear button to turn the phone on it went through LG logo the it turned off again, then turned back on to the LG logo and then it turned off. Two times have I been able to get it to the password screen but right after I have contact with the GUI the phone shuts down. I have tried doing a factory reset, a soft reset, a safe mode power up and a proper shut down by pressing the power button and the 'low' volume button. Has anyone else encountered this issue and found a fix for it?
