Google Nexus 4 microphone not working

[Max Koshevoy]

I have tested 2 phones LG L7 and LG Google Nexus 4
LG L7 (Android 4) can play and record.

LG Google Nexus 4 (Android 4.2) can only play sounds. Microphone is not working.

What is the best way to learn what is wrong?

Do I debug code in eclipse or dbg?

I was able to partly connect eclipse debugger with phone. But eclipse shows many errors. breakpoints are not working.
I just was able to press "green bug" button and selected process got that green bug icon as well.

Do you get the call screen?

Yes. It works in both directions with no difference on both phones.
When I receive call I see 2 buttons (red and green)
When I am calling I see one button (red)

If I press green button when call is accepted but green button is still on screen.

Visually there is no difference. But one phone does not transmit audio only receives.

hmm if it hasn't changed the green button, then something failed. There is a way for you to check your android adb log for an error?

Now it works. Yesterday it was not working. I even rebooted phone.

I guess the problem is my WiFi routers. May be phones were connected to different WiFi routers.

There is no errors in logcat right now

May be I should be able to where traffic goes.

Can you call on both Android devices ? Can you help me? 

I cannot call if i log in with account is not Gmail account. I am writing a chat application and i used webctr-jingle-client to implement voice chat.

Thank you advance.
