It is very difficult for people to hear me when I talk to them over the phone, the microphone used for calls is very weakened.
The microphone appears to be blocked by dirt. How can I open and clean it?
It's all caused by the rubber that expands/stretches/bulges all over the case. The thumbprint sensor is surrounded by rubber. The rubber has a tiny cutout on the right side to allow sound to get to the microphone. The rubber bulges and covers it. I got a razor and tweezers and just cut out enough of the rubber to expose the red plastic with the microphone hole in it. Works great now. It's not pretty, but it works.
Hi, I have the same problem. I strongly believe that it came with an update. Some of the other brands seemed to have the same problem at some point. I started reading how to change the microphone parameters in the "build.prop" file but it far from being easy. I hope a fix will be release soon so I don't have to fight with that.
Hi, I have same issue - the sound recorded by microphone is very silent and very bad quality. I've tested both sound recording and also calls - same issue. I must shout at people during calls so they can hear me. And when the call uses Voice over LTE, because of bad microphone, the sound is terrible.
Either it's caused by last Android update or it's caused by hardware problems, anyway few months ago (e.g. december 2019) this didn't happen.
