iOS 7 brought a lot of features users cared most, in a way solved problem relating to jailbreaking of the iPhone and the iPad. Prior to iOS 7 the Do Not Disturb feature only silenced notifications when your device was locked or in sleep mode. Apple realized this was a problem for users so it was modified in iOS 7, it is now possible to suppress notifications even when your are actively using your iPhone.
- Launch the Settings App from the main Home Screen of your iPhone.
- Scroll down and tap on Do Not Disturb.
- Move to the button under the Silence section, tap on Always boom you are.
Your iPhone will now silence all notifications , not just the ones that come in when your iPhone is locked.
Put in your comments if the above help you solved your problem.
