My iPhone 4S won't turn anything to the sides?

Won't turn videos nor my keyboard. It's been like this so ce the IOS 7 update. Apple had to long of a wait I was waiting 30 minutes and I just hung up. Can somebody help me?

Added (1). @debbie I don't even know where the auto rotation is at all I use it for is calling, tecting, and my email.

Is your auto rotation turned on.

Look in Control Center to make sure the screen rotation lock is off and if it is, you should probably just try to take it to an Apple store to see why it isn't working. But you can turn on Assistive touch to rotate the screen. Go to Settings > General > Accessibility > Assistive Touch > and switch it on.

  • My iPhone literally won't do anything, even turn off? So, I have an iPhone 4S, and i went on the app google, and looked something up, and went on an article, I accidentally tapped a word and now all it's doing issues showing copy, define, and replace, it's blinking as well. And now I can't do anything. Literally anything. Not even turn my phone off… Is there anything I could do?
