Microphone problem

I bought the phone 4 month ago, and works perfectly…Yesterday i foud a problem.I was talking with my friends on skype,when someone called me,and from that moment,my microphone stopped working. When i call someone they cant hear me at all. I have tried to factory reset the the phone, and also to install another Firmware, but i cant solve the problem. Please help.

@false123 From some other forums,

The fix was find the minute hole near the usb connector on its left and clean it with a tiny pin by poking into the hole which cleared the derbis collected due usage. Behold after that it worked fine. I should thank the forum advise. Much grateful.

Also, try switching to the speaker mode while talking. It might get things done until you find a permanent fix by going to the service centre.

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
