Answer to "Fixing the microphone issue"Hi, This was a bad experience with google pixel. All of a sudden microphone is not working after 13 months of usage. Went to Service center to address the issue and got that a complete Motherboard replacement can fix the issue. I didnt go for this as its costs me more. I looked into several blogs on this and finally got a solution at lower cost. 'Qualcomm WCD9335' chip replacement can fix the microphone issue.
