info about engineer menu (microphone and speaker are too quiet)
 

Hello,

i have the following problem:

the phone is an MTK based, resembling Nokia ExpressMusic model.

The sound coming from the speaker while on a phone call is too faint, and also the other party cannot hear me well unless i shout into the microphone.

I don't think it's a hardware problem - it is the same with a few other phones from the same batch.

If i record the conversation and then play it the sound volume is much better.

I am able to enter the engeneer menu (*#3646633#) and there are some audio settings. The question is - which settings do i change ?

Thanks in advance for your help.

Regards,
John
