After audio ic replacement no microphone in phone call but siri works

Can the mic prevent the speakers from working? Also it highli depended on the phones temperature weather it had working audio or not. I mean if the phone was cold there was no audio, sir nor could you record or speak and listen in a phone call but if the phone was warm than you could use al these functions mentioned above.

Nigel,

on a side note, i have an iphone 7 that has mic, but not speaker, issue. siri doesn't work, voice recorder doesn't work. taptic has issues but i think that's unrelated. i was thinking Audio IC, but also the charging port flex. i put the motherboard into the back housing of a different iphone 7, but it did not improve things. i would think this confirms audio IC problem.

would you agree? or are there other tests i could/should run?

@mesugemesuge the bottom speaker connection is on the same ribbon as the microphones and charging port.

@beekerc I would fit a new charge port assembly before anything else. Mic, speaker, taptic and charge port all on there.

hi Nigel

i effectively did that. i put the questionable mobo into a different back housing with a charging flex and taptic that work. that's the same as installing a new charging flex. i have another IP7 housing i can try, but i'm not thinking the charging flex is the answer in my case
