Chosen Solution

So I have iPhone 7 plus, mic is not working, neither siri or voice memo, siri shuts down when you press, and voice memo doesn’t even start to record. So I assume it’s IC sound chip that’s seem to be a common problem, but could it be the mic itself? Before I proceed is there anyway to check if it’s the mic itself or chip?

Voice memo and Siri use different mics. You defiantly have the dreaded iPhone 7 audio IC problem.
