priority mode is setting on by itself

[buspilot]

Hi everyone.

Pressing the volume button opens at the notification bar  "silent-priority-sound" menu.

I choose the priority option for 2 hours only and it comes back to sound after 2 hours.

The issue is that sometimes at different hours of the day the priority mode is getting on by itself (the star is on) and I miss calls without realizing it.
I choose the right settings
Settings > Sound & notification > Interruptions >
but the problem still remains.
the priority mode is all-best-feature and very useful for me because I do not want to be disturbed when i'm sleeping but I have to look always if the priority is set on by itself.
Any suggestions?

Is it possible you have a 3rd party app causing a conflict?

@buspilot

any antivirus? taskillers? stamina mode on?

[buspilot]

Thanks fot your reply.

Stamina mode is on.

When I purchased the device there was already an antivirus "Look out"

The only 3d party app that may cause the interruption is "Battery doctor".

 Should I uninstall it?

Boot in safe mode,see if the same occurs:

@buspilot you should uninstall both apps > restart the phone > report back

The battery app yes and if it's AVG again yes - If you want to use an AV app then use Avast

alexdon and uliwooly thanks a lot.

I 'll try your suggestions and inform you.

Unfortunately there must be a 3rd party app which causing a conflict.

I boot in safe mode and the sound was on all the day after the priority mode was closed.

So I have to search for the 3d app by uninstalling them one by one.

Anyway @Thommo @uliwooly @alexdon thank you all for your advices

It could be an antivirus or some app with access to system settings or sound settings.
