iPhone 4 mic not working during call
Hi,
probably this question has been asked many times
here is my problem
i have an iphone 4, during incoming or outgoing call, i can hear other people, but other people can't hear me, i've tried speaker mode,same thing. have not try headphone with mic yet.
i tried to go to camera, and record a short clip, i can hear my own voice though, so it is only happening during calls.
here is what I've tested so far
i have another perfectly working iphone 4, so i began to swapping parts.
first, i swapped the motherboard only, and it seems like it is not the motherboard. because the mic problem iphone motherboard transfer to a good phone, and i can hear people and other can hear me.
and the good iphone motherboard on the bad mic iphone housing still have the mic problem.
my guess i narrowed it down to the housing.
so continued swapping the bottom speaker, bottom mic and charging port, it seems like these parts from bad iphone housing to a good iphone are working.
so it doesn't seem like problem on lower mic and charging port, lower speaker/antenna.
what else should i try?
Es esta una buena pregunta?

Has the phone got any type of damage before? If not then its probably because theres connection problems. Or it can be because its old. Is it old? I had the same problem before thats why im telling these advice.
