How to fix a touch screen phone(Samsung bright side)
I have had a couple of problems with my Samsung just recently. I think it is because of upgrades to the software. If you shut down the phone once a day for a couple of days, it seems to do the trick.
How fix, fell in water, dropped and isn't working or exploded
You're gonna have to go to the place you bought it. Do you have a screen protector? Maybe it needs to be replaced.
