[Ashokramboll]

Hai I am using Z3 Dual. I have an issue, Ringtone & Notification Volume Automatically Increased. If I modify the volume, it doesn't consider anymore. Next time it automatically get increased. Even though I have modified each time but recent day's I have annoyed to change the volume of Ringtone and notification again and again. I don't know what to do. Has anybody having solution for it.?

does this happen when you are in safe mode?

if it does, it mean that an app is causing this.

try to check your audio settings

I have checked via safe mode.

But the problem not solved.

Still i am getting issue.

Are there any volume lock control available. but it should not affect system UI.
