i9300 microphone & earphone not working during a call - GSM-Forum

meshkat_azizi · 11-17-2014, 21:42

Hello everyone,
I recieved a samsung i9300 with android 4.1.2 which works properly until it recieves a call then the microphone, earphone and its speaker stops working but after the call everything is allright again. What i did was first wipe the device then checking the microphone way and changed every resistors and audio ic from a working phone. But my problem is not solved! Do anyone has an idea?
Thanks in advance

Check if ur phone have n/w while in call.
Am workin @ samsung service.
Hav got the same issue , no audio while call is connected . I hav observed that the n/w goes down while call is connected.
Changed the n/w oscillator nd problem was solved. Try it.
Best of luck buddy...
