A number of android users who updated their phones to Android 6.0 Marshmallow have complained that a bug has changed the behaviour of their automatic do not disturb settings or has prevented it to turn off completely.
In most cases, this problem occurs when your phone goes off or restarts while ‘Do Not Disturb’ is active or has a timer running in automatic rules. When your phone goes off while the do not disturb timer is still running
Someone recently brought his phone to me and asked me to help fix this problem. At first, I thought a virus might be causing it, until I checked the version of Android running on the phone.
Even though a simple device restart helped fix this guy’s problem, it unfortunately didn’t work for some others. Depending on how you use the do not disturb feature, a different approach might work for you. Check them out.
Restart Your Phone
Hold the power button to turn off your android phone. Leave it turned off for 10 minutes, then turn it back on. It has worked for some, and It might work for you too and help disable do not disturb on Android Marshmallow.
Volume Down
Keep pressing the volume down button until it goes into silent mode. When you turn the volume back up, it should pop up a request asking if you would like to end do not disturb mode.
Priority Only
Navigate to Settings > Sound & Notification > Priority Only Allows. Change ‘Calls’ from None to Anyone. Now turn your volume up once, if you get a notification to end do not disturb, confirm and choose end now. If not, turn your volume all the way down to silent, then turn it back up. Now try calling your number from a another phone to see if the problem is fixed.
Custom Rule Countdown
Here, you are going to set a timer to turn off do not disturb automatically.
Go to Settings > Sound and Notification > Do Not Disturb > Automatic Rules. Create a new rule, set it to expire in 15 minutes (to make it quicker, set it to start 10 minutes in the past and end 5 minutes later. Or 13 minutes in the past and 2 minutes later, however you want). When it’s running, allow the phone go into sleep mode. Do not disturb would be turned off when the timer runs out.
Factory Reset
A factory reset always works, but it should be your last resort if all else fails.
Did my recommendations work for you? Please let me know which fix did it for you by leaving a comment below. Thanks.
