So I just got a SG2 a couple of months ago and I love the phone except for one weird problem:

yesterday I noticed that the battery signal is flashing like crazy. a weird battery screen appears with some white dots at the bottom and then goes away on its own after a while and then i can see the battery signal with a thermometer next to it. i guess the phone is trying to tell me that the battery is overheating, but neither the phone nor the battery appear physically hot or warm. and it keeps on doing it from time to time making my phone unusable.

should i get a new battery or is this a serious problem?

I have exactly the same problem, actually, and the worst part is that i can't even charge the phone when that screen is flashing. I am soooo pissed offf right now!

Hi there.

This is a common enough problem.

I experienced the same issues and this is how I fixed the issue.

Take the battery out.
Get something thin like a pin or tooth pick and clean the inside of the charging port. Ideally you would have some sort of proper electronic board cleaner like isopropyl. - make sure not to do so too forcefully.

Did the job for me.
