Mic gets low for other side?

Hello, When I put the phone on speaker and or use a headset it lowers the voice for the other people. I can hear them fine both ways. It is just during headset or speaker phone calls. It works perfectly fine when talking normally through the phone. Hardware problem? I just noticed it, can I exchange it through sprint? Please advice! I am on 4.2.2 d3rp rom still on ZV8!

When you put it on speaker phone, it uses the secondary mic at the top of the phone instead of the normal mic at the bottom. If you look at the top of the phone there is the infrared port on one side and then a small hole on the other side. That small hole is for the secondary mic. Try talking into the top of the phone when on speaker phone and that should solve the problem. Headset issue I can't help you with. Each headset normally has a built in mic usually near the volume controls. Its probably bad or you're just not directing your voice into that mic or something.

I've tried to do that but still the other person can't hear me thank you for your input tho!

Microphone issue

Mi Max 32GB V8.1.4.0.MBCMIDI
The caller will not hear me, but when turn on the speakerphone, the caller hears me well. In the service menu microphone tests everything works.
When I record my voice recorder.app everything works well. NOT working only during a call, in Skype not working too. Maybe you know how to fix this problem. Maybe this is software bug ? or broke the microphone ?
p.s. Root installed

Still problem

Hello,
This may be because of Camera issue, there are two microphones in the phone, one is the upper one next to the Earphone Jack and one at the bottom next to Speaker. When we are making a movie from the camera in Landscape mode, phone is switching to the upper microphone, (this is a noise reduction microphone) and when we make a move in Portrait mode, this is switching back to the bottom mic, somehow, when are closing the camera from a Landscape mode, phone is not switching back the mic to the bottom one, and still set for the upper mic, causing a very low sound going out for the phone call, as we are speaking at the bottom and the mic is at the upper portion. When you are turning the speaker, the bottom microphone is turning on, hence the voice is clear at the other end. Try doing a little trick, switch on your camera, record a movie in PORTRAIT MODE for 2 to 3 second and close it. Now try again doing a call, to my understanding this will work, as this works for me. Please update if this works for you as well. Best Regards

THis landscape-portrait camera trick doesn't work on my phone.
My upper microphone works (noise reduction mic works in loudspeaker voice microphone mode). But bottom mic doesn't work. I replaced this mic, then i replaced bottom board and its flex. Nothing helps.
1.8V comes to the mic.

Which sensor is just above the volume buttons on the side of the device?

I just put a case on my g8 and noticed this cutout... what sensor is this?

Microphone, which complements the two on the top and bottom.
Using the audio recorder, you'll see it only records mono when the phone is vertical. I believe it's using this long mic then. When you turn to landscape, recording switches to stereo, using the mics in the head and chin of the phone.
If you shoot video or record audio, you'll hear how great the sound recording is. I could be wrong, but I think that all 3 mics are constantly in use for spatial sound recording and background noise reduction.

It's a noise canceling microphone, or far field/wide range mic, for spying/listening for assistant input from a far. Or both.

Yes normal, the top mic is for noise cancelling only...

help, main mic is broken. how to set up sub mic for calls?

Hello everyone, a while ago I dropped my phone and now the main mic is broken (the one near the charging port). So I can't record audios or make calls without using a headphone with a mic. BUT WHEN I RECORD VIDEOS THERE IS SOUND. I think that's because of the noise cancelation mic(the one on the upper right side of phone) For some reason it's activated during the video records and captures the sound.
How can I force my phone to use secondary microphone all the time? So that I can make calls and record sounds without changing the primary microphone.

well, I'm not a programmer but I have been trying to edit audio_policy. conf and audio_policy_configuration.xml files.
Apparently there are 2 input sources for microphones. built-in mic and built-in back mic. I have tried deleting these or somehow ' disabling' them. but nothing happened. I can still capture sounds while recording videos but the very same damn microphone wouldn't work while recording voices.
How hard is it to simply disable the main mic and use the noice cancelation mic as the main one? I'm sure you programmers can figure it out better than me ??

I'm facing the same issue, have you found any hack for that ?

Any luck bicho2015? My main microphone died on my Pixel 4 and I would like to reroute to the other 2 built-in mics.
