Turn off the power for 5 minutes the take out the battery for five minutes. Then put it back in and turn it on. I tried other ones but this was the only technique that worked for me.
I have the same problem with my gs3 ever since I made the update, but it only happens when I text certain people. I don't get it. I tried deleting twitter but that didn't work. This is really confusing and I need it fixed please help me someone.
