Is anyone else having trouble taking a screenshot? I don't know what would have changed, but nothing happens when I hit the power button & home at the same time...the home button doesn't vibrate to acknowledge it's being pressed, and I'm eventually greeted with the shut down menu. It always used to work for me with no problems. Restarting the phone didn't help either. By the way, I am NOT rooted. Any advice? Hope you guys can help!
