Standard bottom microphone don't work
Like i said in the title, bottom microphone of my iphone 4s don't work. The top one working perfectly. So i can use the iphone only on speaker or with hands free earphone.
When i record something with voice memos, I can hear on recording very low volume radio frequency noise. When I try to talk with someone, they can't hear me, only the same very low volume noise.
I already changed the microphone and nothing happened.
What can I do?
