[Q] very quiet voice only in calls
I have a strange problem with my rooted Haier W910 Smartphone (Qualcomm Snapdragon S4 MSM8260A CPU with ICS 4.0.4).
In all calls, the microphone is very low and everyone hear me very quiet.
But in all other apps, like voice recorder or google speech recognition, the mic works fine and perfect.
I hold the phone properly and also I don't touch the mic with my fingers in the call.
I can't edit something in the phone options and I don't know / can't find the right secret code for service or engineering mode
Who can help me, please?
Best regards and sorry for my terrible english
