Already asked on XDA and the Android Questions subReddit but got no replies.
So I have a factory unlocked international Note 2 (GT-N7100). Supposedly from Spain originally. Anyway, my in call audio hasn't worked for a while. I noticed it a month ago but I use a different phone for almost all of my calling and the rest I use VOIP apps for so it may have been that way for over a year. I basically use it as a tablet with the occasional VOIP call but I'd like to have the phone app working properly.
At some point I flashed a Samsung official ROM from South Africa (if I remember correctly) as they had a newer Android version than mine and it wasn't saying an update was available. Everything worked great except maybe voice calls. I have no idea if those worked before I discovered the problem recently.
Last week I tried flashing a custom ROM hoping it would fix the problem. During this process I wiped all the partitions. In the end that ROM (Ditto Note 4 if you're curious) wouldn't get past the Samsung boot screen so I gave up and reflashed the latest unbranded stock ROM for France.
Problem still remains.
I tried poking around in the hidden diagnostic menus (where you can enable and disable different frequency bands and stuff like that) and found one for Audio but clicking on it does nothing.
I thought maybe I could modify something through QPST but that tool only works for Qualcomm chipsets and this thing has a Samsung Exynos chipset so QPST wouldn't talk to it. I can't find anything similar for the Samsung chipsets.
I read that that Audio menu was blocked out by Samsung on some newer radio firmwares so I downloaded the original ROM from 2012, extracted the modem firmware and flashed it. Menu still won't work so I went back to the latest. Still no audio.
I don't think it's a hardware issue because the mic and all speakers work great on VOIP apps. It's just when I call there is no audio in or out of my phone. Doesn't matter if I'm using the headset, speakerphone, or an external set of headphones (with mic). If I press keys I can hear the DTMF tones on the other line but no other audio. Even from the diagnostic tests when I run the Receiver audio test I do hear the tone.
I did at one point have the thing rooted and I think tried swapping the phone app for a different one because the dialer codes to access those hidden menus weren't working but I assume that should've all been cleared up when I did the wipes and reflashes. I have since found out what the new codes are to access the same menus.
Any ideas? Or if you can explain why it could still be hardware even though the hardware works for all other purposes, I'd appreciate it.
