Try running a power cycle = hold the power button till the phone shuts off then re-powers and you might try running system cache clear it's not like a Factory Reset but it can sometimes straighten out phone issues.. If the issue persist you might removing the Sim Card do it with phone off use care when removing leave it out for 10min. then reinstall..
Give these suggestions a try let us know if it Helped. b
