Muffled voice quality on outgoing Z10 calls

I've had my Z10 for sometime now and have occasionally been told that the calls on the other end have been muffled.

Lately, I've been getting more complaints.

Has anyone else experience this with the Z10 and found a solution?

Any help would be much appreciated.

go on amazon and buy the screen assembly about 14 dollars ,it comes with mics and tools then watch a youtube video how to replace it
it took me 5 min first time

Thanks, much appreciated.
