I have a i9192,
I'm using stock rom and kernel I9192UBUBMK4 Stock.
I have a strange problem, when I make a voice call ...
the other person hears me bad, the volume is low then it is high, then low again.
I hear the person correctly without problems.
but she did not hear me well.
someone has been there?
excuse me for my English, because I'm using google translator.
