Hi guys,
I need advice regarding voice over GSM.
The problem is that I have a terrible noise in GSM calls. Speaker and microphone are OK, cause everything is perfect during calls on Viber, Skype etc. (and I changed them anyway - speaker and mic).
Which part on PCB is responsible for this? Maybe if you could point it out for me, I could take a closer look.
It is not signal related (3G works flawlessly).
Any advice would be much appreciated.
