When I bought the phone, it was on Android 6.0
The sound was just good.
Then it was upgraded to 7.0, the perfect upgrade that turned my phone into a real beast in terms of headphone levels.
From the time I upgraded to 7.1 and ever since I kept upgrading after it, the headphone levels still remain low.
I was hoping Android Oreo would fix it up and revert the levels back to where 7.0 was, but it didn't.
Is anyone else aware of this issue?
