[Mhaggag]

i just bought z2 and after  2 weeks

the mic isnot working

the peopel inforent of me cannot hear me talking

i hear sound of hissing when i record a video

i do know what is the problem

some people say i must change the mic 

but if i did does that mean the phone is no longer water proof

i do not have a garentee on my phone

Check if microphone noise suppression is enabled.About the other problems,I suggest you to stop by a sony service.
