Microphone issues on iPhone 6

iPhone was in water and sand few days ago and now microphones are not working. I tested all 3 microphones with Auphonic app and by recording video and all of them sounds like someone blowing air directly to microphone.

On bottom microphone my voice is barely heard.

On top front and top back microphone there is just strong wind and nothing heard even when i shout right at the microphone.

I tried cleaning microphones with tissue, cloth, toothpick and even a sticky gum but no difference.

I want to know how can i fix it. Any help is appreciated :)

Assuming the water didn’t get into the phone core, the logic board, you may try replace both parts that seem to be damaged, or clogged by sand. Here you can find the guides that can help doing the job..relevant parts can be purchased on iFixit store too, you’ll find the links within the guides pages.

Thank you for your answer! I don’t understand if i should replace earpiece speaker or front camera and sensor cable for front speaker. Also can you please add link for the back microphone replacement guide.

@numan99 Earpiece speaker gets and transmits signals through the camera/sensor/upper microphone flex cable. Given the problems the phone suffered I'd replace them all once you're doing the job, parts come quite cheap anyway. Rear upper microphone is on this other flex and relevant guide: iPhone 6 Power Button Cable Assembly Replacement
