Quiet call volume

[szerwony]

Hi. I have problem with very quiet calls. It's really hard to speak with someone when I'm outside because I can't hear them. I think it's not speakers problem, because they play music properly. I'm now on eXistenZ Marshmallow, but I had this problem also on stock Sony Marshmallow. Do anyone know how to repair it?

Did you replaced the screen ? it's common , the speaker become faulty when you change the screen

I'm not sure because I'm second owner of this phone, but I think screen or speaker was changed in Sony service.

Solved

I one had that problem.
It was really annoying and made me nervous ...
I did a lot of searches and tried everything that could solve the problem, no success. I almost gave up.
I finally found a thread here in xda that gave an unexpected solution, it worked like a charm.
The solution was to clean up the speaker using a needle or something similar. I actually found the speaker was almost totally covered with dust turned into a solid paste because of sweat, water droplets, ...
I'm very satisfied by the result. I would like to give credits to the guy who wrote this first but I don't remember the thread where I found this solution. Sorry.
I hope this will help whoever has the same problem.

I have already tried that, no improvement. Maybe there is any app or mod for increasing speaker volume?

I had the same problem and a needle didn't solve the problem. I looked under a Microscope and the needle tip was still too big for the tiny speaker protection matrix. What I did is I used a chewing gum (works also with something other sticky like blue tack) and pressed it in the speaker and when I took it out, loads of dust was sticking to the chewing gum. I repeated the process a few times and the speaker volume was ok again.
