Do you have a taskiller? antivirus? Ram app? booster apps?

Try settings-apps-all-scroll down to settings app,clear data and force stop.Restart the phone.

If the suggestions above doesn't help, I would suggest that you try to boot your phone into safe mode to see if the problem may be related to any 3rd party app that you have installed in your phone:

Yes I do. Clean master and CM security

Remove any kind of task killers or phone optimizers.
