iPhone 7 Plus microphone issue (solved)

Hello all - I would like to inform you that I had microphone problem(can’t hear from other caller vice versa) with my iPhone 7 Plus . I try to follow so many steps like reset all settings , reset location & privacy settings . Even I visited Apple Service Provider for diagnosis . Apple Service Provider asked me Change the mic with the cost of €340+(Approx).

diagnostic report came as some problem in audio but it didn’t show as red flag.

I took a decision to reset and erase all contents and setup as new iPhone.

it worked without any problem.

this posting is for Someone who is facing similar issue.

good luck

thanks
