Microphone is not won't work even after replacing it with a new one!
my m7 had the pink camera issue for which the phone was opened and the daughter board was changed.
the phone was put back together and was closed with a new back cover.
now after turning the phone on the primary mic has stopped working (the secondary works though).
i've also bought and replaced the mic + usb flex cable today, thinking that the flex might have been damaged, but it didnt seem to work... The usb port and the bottom speaker work properly, the issue is only with the microphone.
(note: the usb port did work properly even before replacing the cable)
would highly appreciate it if someone could get me out of this mess.
