If you updated over your old system, some residual files might cause instabilities. Turn off your phone and leave it on a wall charger for 2 hours, optionally start the phone to backup any important data, then proceed to perform a software repair using PC Companion using PC Companion. This will install a fresh copy of latest firmware on your phone removing any software glitches.
