Do not disturb still rings on 4S
I turn on the do not disturb feature but my phone still rings normally.
I have no favorites and the phone is locked.
No scheduling is set.
Generally it will turn on and work normally but after some time has passed it just starts ringing again although it shows as still on.
I do make phone calls and send texts while in do not disturb mode which may or may not trigger the problem.
Anybody????
iPhone 4S, iOS 6.1.3
