ios 7 proximity sensor not working
Since upgrading to IOS 7 on my Iphone 4s there seems to be problems with the proximity sensor. Taking calls with handset no longer locks the screen and contact with face inadvertently presses keypad numbers resulting in dial tomes mid call. Never had this issue with IOS 6. Is there a setting I can change to rectify this or will I need to wait for next update of IO7 and the problem is sorted.
iPhone 4S, iOS 7
