Can't do it. bought it new from someone
Is somebody that solved this issue? VHollund?
That someone should have a warranty
In my case I bought it from internet store in france and we have 14 day retraction right + 2 years warranty, so I send it back
It was not a software problem
You can test the microphone by going into the systems settings on the phone
If you have no warranty, you can use a head set which is what I do most of the time anyway not to get my brain fryed
It will stil work on speaker sphone where the 2nd microphone is on
Some developers might be able to help you hack it to use only the 2nd mic
I've seen inconclusive threads about it
