Vibrates for notification even on silent mode
I just started to have the problem of HTC m8 vibrates every 30 seconds for notifications such as missed called, SMS or other app notifications. It is on silient mode but won't stop vibrate and it drives me CRAZY. I can't figure out how to fix it. It started a few weeks after the lollipop system upgrade. I really hate the new system, but don't know how to downgrade back to kitkat. And i don't know enough to do flash stuff. Can anyone help me please. Thanks.
