My Samsung Galaxy S2 won't switch on since 01/08/2013 till now... I've checked the Internet, it said it might be the battery's problem and I'm not sure whether it's true or not. My S2 switch itself off suddenly with no reason, I tried so many time to switch it on and it still not working. I hope there's a way to switch it on, because there's a lot things in my phone and I haven't take it out. Please, I really need you guys help! Please and thanks!!
