iPhone 6s Crackling Microphone. No issues on speaker.

Hi there,

I've had 2 iPhone 6S recently with the exact same problem. When speaking to someone, the microphone sounds very crackly. When they use headphones the sound is clear.

I've done the basics such as replace the charging port. Clean the bottom speaker holes. I changed the camera up top in case it was the proximity sensor.

Has anyone experienced this?

Thanks

Update (09/28/2017)

In an interesting turn of events. After trying a 2nd new charging port it solved the issue.

To clarify:

- Phone presents with microphone issue

- Replaced charging port still has exact same microphone issue

- Replaced the charging port again and it solved the issue.

It's most likely an audio ic chip issue causing the problem.

This involves replacing the audio chip on the logic board which is quite difficult as it requires microsoldering to do so.

I think Minho has more info on this.

Thanks for your educated answer. I have learnt that it could be the connection of the charging port to the motherboard being slightly loose. Once I get my hands on one of the 6S's again, I'll test it out. If they're not loose, I will accept your answer. Thank you.

Why not change the microphone to have a try. Here are the videos about how to tear down and reassemble iPhone 6s. iPhone 6S Plus Full Disassembly/Tear down iPhone 6S Reassembly/Put Back Together Note: Tear down have a risk

Perhaps we could get an answer from someone who has some clue about what they're talking about?

For future reference, the microphone is attached to the charging port.

Yeah, the microphone is on the charging port and it is easy to replace with an disassemble video.

Thanks for taking the time to read what I wrote before spewing out your mouth.

Oh I found the answer to this I think. There’s a microphone in the power button. Connects near the rear camera. Think that solved it, can’t remember now. Feel free to contact me at aaron@moffit.com.au
