Blank screen, intermittent vibrate when plugged in.
I got a phone from a friend who asked me to fix it. The issue started happening after he left it in his car for a few days in really cold weather. It won't switch on but it vibrates every 10-15 seconds when plugged into a charger. I was thinking it maybe either condensation damage or a software issue. Has anyone on here heard of this before?
Thanks in advance.
