Hi i have enough of vibrations waking me up before alarm which I set up any chance to switch them off completely phone calls notifications and still hear alarm
You can control the functionality of the DND feature on the Z3 by navigating to the following location:
Settings > Sound & Notification > Do Not Disturb
Here is a short guide below on all the things you can do in this mode. The information is about the Z3 compact, but the information should be relatively the same.
