Microphone problem in calls, no sound

wanagain79

I have seen exactly the same issue with the Samsung Galaxy S2:
-> Very low and bad sound with SIP and GSM calls
-> Echo's issue with the front speaker and no mic sound with GSM and SIP calls

The only way to solve this issue (without return back the phone) was: desactivate the rear mic with a firmware tips (XDA dev made a MOD) or disassemble the phone and disconnect the rear mic... So in my opinion it's hardware as the Galaxy S2.

Hello,
same problem here!
I received mine today, and i am so disappointed to find out, that the mic is not working on calls. There is even more: the phone gets so hot during calling, i have to be careful not to burn my ear. The ROM is v1.5, but as i read here, there is no use to install the v1.6 since it doesn't help either.
Please help!

So I got a feedback from UMI (over Comebuy.com)!

They want my phone back for investigation...
Its a very bad solution for me! I had to wait for this phone 4 Weeks, and after 2 days in my hand I have to sent it back to china "for investigation"....so another 6-8 weeks were gone!
And UMI, sorry but I don't believe that is a single case issue (you can see here in the forum).

I have this bug also, but it appears randomly, but usually, when I activate and deactivate airplane mode. Restarting the phone helps me solve the problem.
