p3100 mic working in camera default app no in other app

Hi
I have a a p3100 samsung galaxy tab 2 3g 16gb internal memory, I had with android 4.1.2 and to fix the problem I just update to 4.2.2 french stock, but the problem still is on.

The microphone only work in the camera default app, but no in others app like smart voice recorder, or even in call, if I receive a call I need to activate the speaker so then the microphone get activate.

google now don't detect any voice.

I juts installed an app called easy voice recorder, it doesn't record any voice, but It has a option to select the microphone, first time I see that, and I chose back microphone and this app now it record the voice, but any other app doesn't have this option to select this back microphone thing.

so how can I activate the microphone in my tab 2 always, by default.
thanks

Bricked Galaxy Tab 2 P3100

Hello XDA !

I have a Tab 2 P3100, bricked with Odin. I was using a flash file that I've used many times before on the same laptop, with the same cable, and the same tablet.

Something went wrong and Odin displayed an error saying there's no PIT partition .

I've tried to use different PCs and cables, still not working.
I'm stuck now at the emergency recovery page, and when connected to Kies it just hangs on "Connecting...". The device does charge alright but I cannot turn it off (it reboots instead of shutting down when I long press the power button).

I think it might be going into download mode when I hold power button + vol down, but I'm not sure as it gives me a blank black screen and gets a bit hot on the left upper corner.

Any Ideas ?

Thanks in advance! :)
