What the hell is wrong with this thing. It's starting to p me off...
I have bought another, genuine Samsung battery from the guy who rooted my phone. When he put it in it was fine, it was less than 10% so I switched the phone off and connected to the USB in my house. The percentage came up to 20% in about 2 minutes and then it jumped from 20 to 100% with a sound that the battery is fully charged. But then when I turned the phone off there was the same sign with the thermometer and the battery flashing... On there it was showing less than 10% - so I thought I could charge it with the phone being turned off. Nope - it went to 20% and the jumped to 100% aswell. Also when I connect the USB or the adaptor the screen blinks... is it a USB port problem?
What should I do?
