My Display only rotates horizontally but does not rotate vertically. The display lock is not on. I restored back to factory settings and am still getting the same problem. Any ideas on how to fix?
iPhone 4S, iOS 5.1.1
first thing I would try is rebooting the phone by holding the sleep/wake button and home button for 15 seconds until you see the white apple logo
if that doesn't work I would restore from backup and if that doesn't work I would restore as new if all else fails take it to your closest apple store they may replace the phone for a working one.
