In-call volume trouble. Always at highest. Doesn't save.

[Mustafakosker]

Hey people,
I am facing trouble with the in call volume of my xz. The problem is that whenever I receive a call the volume is at the highest. I lower and change the volume during the call but the next call it is again returned to the highest volume. It is really teasing. I think this happened after the Nougat update. How can I resolve this issue?

does this happen when you are on safe mode?

[Mustafakosker]

No it happens on the normal mode. Never tried it on safe mode.

@Mustafakosker

if you don't experience this in safe mode then it's a third party app acting up

@Mustafakosker, no I meant, can you try it on safe mode.. just to eliminate the probable software problem,
