iPhone 6s Crackling Microphone. No issues on speaker.
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?
Is this a good question?
