Question on samsung J7 2016 model

[Rocky Williams1]

I have noticed a peculiar issue with this phone. In call volume adjustment behaves weird on this phone. If I reduce the incall volume to half during a call it is same as it would be at max. Infact it is slightly more than what it is when it is at max. Has anyone faced the same issue? I am wondering if it is a hardware issue or it's the just the way phone is built? This phone is running on Marshmallow.

I had to do a vol hack with J7 2015 model ; the vol was very soft

Samsung released september update for J7 2016 model and it seems they have fixed this inconsistent volume issue. However the volume still continues to be soft and if someone is at a noisy place it is barely possible to hear someone.
