My Samsung Focus Flash have been giving me problems for at least a week now. I am unable to do ANYTHING on it. Whenever I try to send an email,play a game, watch YouTube videos, talk on the phone, etc... My phone shuts off about 2 minutes later (as if it overheated or something). I can't even turn it back on immediately, I have to wait a few minutes or plug it into a charger. I can only do things if my phone is plugged into the charger during use. I think it have something to do with the battery but im not too sure. This is only a 4 month old phone! It is very annoying! Anyone else had this problem?
