lg g4 froze while playing a game. i pulled the battery and replaced it and the phone booted up. it was almost done booting and it froze again but this time there was "snow" from the bottom of the screen to the halfway up point. I pulled the battery again and now it wont turn on. when i put it on any charger the battery charge indicator does not come on. I tried holding the power button for 30 secs and nothing. Tried holding the power button and volume button and nothing. Called tmobile and they couldn't get it to turn on either and stated it was probably a bad battery but if its the phone it is out of warranty and i would get a $37 credit to trade it in on a phone that i owe $150 on still!!! Does anyone think a bad battery would cause the problems i am having? thanx!
