how does the do not disturb feature work is it only when you phone is in lock screen mode because when my phone is open it doesnt work
I noticed that my phone rings whenever the phone is not lock but as soon as it locks thats when it doesnt ring.....this is very annoying because the feature should work in both modes, is this just happening to my phone or is this how this feature really works
iPhone 4, iOS 5.1.1
