Sometimes you just don't want to be disturb by incoming calls, new messages or emails, and you just want to disable all notification on your Android. Galaxy owners (including Galaxy Note 3, Galaxy S4) have the advantage of using Blocking Mode to disable all (or some selected) notifications at specific times. To disable All notification on Galaxy Note 3, do as follows:
1. Open Settings and tap on Device tab
2. Scroll down to the end and select Blocking Mode.
3. First enable Blocking Mode, and then select the notifications you want to disable. Available options are: incoming calls, notifications, alarm and timer, and turn off LED indicator.
4. You can also set time, and create the white list (allowed contracts)
