i9505 Secondary Microphone - GSM-Forum

goldboxgsm · 11-14-2016, 11:23

Hi, guys!

I've got one Galaxy S4, and, when video calling (skype, whatsapp, facebook call), the other end doesn't hear me at all. So, that's the secondary microphone.

Where is the secondary microphone in Galaxy S4?
At the top of the motherboard, there are 2 microphone-like pieces, but which one of them is "guilty" for not getting the sound?

Anyone? Any ideas?
Thanks!

The secondary microphone is the highest one, MIC1000.
If you download the service manual you can see it.
