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.

The cool thing about the phone is that I can put it faced down to automatically turn the speakerphone and the dual microphone on.
But what if I want to do it while holding the device on my hand? I tried putting it faced down on the case (on my palm) but since it's not exactly flat, it's not working as it should
If I press the "Speakerphone" button on the TouchFlo 3D while having a call, will that give the same functionality as if the device is faced down?
Once you dialed the number just press the "Speaker" button.It works for me.
So it will also turn on the dual microphone with noise cancellation thing? Cool, good to know!
my TP2 doesn't turn speaker on.....when face down during calls....it keeps speaker off!!!!!!!!

Did you make sure your G-Sensor is calibrated?
yes am sure .... G-sensor works perfectly
works with Light sensor
After some tries I noticed Speaker was enabled with both Facedown AND Lightsensor obtured...
to my knowledge both mics work all the time whether your on speaker or not
Ah alright, good to know. The reason was because sometimes my friends went "Huh? What did you say?" when I put them on speaker mode (inside quiet my bedroom). I guess I still had to shout even with a dual microphone + noise cancellation
press and hold the call send key whilst making a call to enable both speakers.
in settings»all settings there's mic input control option (second option on mine) which supposedly increases or decreases the volume of sound captured by the mic to make sure it is not too loud or too soft. Unfortunately when I had it enabled everything captured by the mic was extremely quiet. Even with the audiorecorder if I had the mic right next to my mouth it was extremely low. So maybe it is because of that. Try disabling it, maybe your friend will hear you better.

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.
Hi. I tried doing factory reset and roms/kernels, I think my camcorder mic have hardware problems. The other microphones are working fine. I can make calls and record audios without problems but whenever I try to record videos, It has this very low sound coming from the mic (near the rear camera), the only way voices can be heard is if you put your mouth near the mic.
My question is, can I manually increase the reception of the mic (near the rear camera only) ? Or is there other ways to just disable this mic and just use the 2 other microphones whenever I record videos.
Thanks guys.
There's noticable noise suppression in video recordings which really affect the audio quality. As much as I like it on phone calls, I don't always record voices when shooting video. The noise suppression really destroys the sound of the environment. Anyone know a way to disable it?

Only way which I think is shooting in manual mode and disable wind filter, and optionally use HiFi audio recording which will enable recording sound track in lpcm.
But I very much doubt that tiny mics of G7 are capable to correctly picking ambient audio of 10-20 dB volume levels. They're too tiny, you should rely on external USB microphone with much higher sensitivity
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.
