Lower Mic not working on voice memo and calls after repair
After replacing my earspeaker (with flex/power cable) the lower microphone stopped working (microphone not working during calls or voice memo).
When recording a voice memo and playing it later I can hear some clicking noises.
People who are calling me say they here noises like a fax or something.
I've tried to replace the dock connector with microphone but this didn't help.
Tried to clean all the grounds/connectors with isopropanol, didn't help.
With a headphone/microfoon connected memo and voice calls is working.
Any help/tips are welcome!
