i have a galaxy s ii i9100t and the microphone levels are really low...
i tried replacing 4 diffrent microphones and the problem is still there, so i tried to flash stock rom,
i tried 5 diffrent roms at diffrent android versions and the problem is still there.
I tried dialing *#197328640# and it's says AUDIO IS BLOCKED at all the roms that i tried (see picture below).
i tried to root the phone and install ExTweaks to amplify the microphone which i did, and there was no effect.
what should i do?
