I turned off my Samsung galaxy S3 mini and placed it in my bag pocket. When I took it out to turn it on it was not turning on. I have tried taking out the battery and charging it but nothing happened. I even tried the safe mode. HELP
Are you only clicking the power button once? If so, try holding it for 10 seconds, letting go, and then holding it again.
It could also be a battery issue, so if everything fails (ie. my solution, other people's solutions, going to tech help, going to the place you bought it from, etc) then I suggest just buying a new battery for around $20.
