How to get rid of lock with circle around it on iPhone 4S?

I think you are talking about the orientation lock at the top right corner of the screen… It makes the screen stop rotating when you hold it at a certain angle when you are on the web, messages, etc.

The fix is really easy… If you are on ios 7 pull up the control center and just click on it

If you are on ios 6 double tap the home button and swipe right (I believe) :) hope this help

Turn it off. Pull up Control Center (on iOS 7 or later) & you'd see the same icon on the top row of icons. Tap that. Done.
