tl:dr; Based on your observation that it works with Moto but not with LG, my guess is that it is due to conflicting TRRS standards -there are two standards. OMTP which is the older standard and CTIA/ AHJ which is the standard all newer Android devices are expected to follow Details and solutions to overcome are listed From TS/TRS/TRRS/TRRRS: Combating the ...

The second microphone is used for noise cancelling. The phone uses it to listen to the external environment (not including your voice), so that it can filter that out from the sounds it hears using the main microphone. That way, it can reduce the amount of noise that comes with your voice, and make your call more audible to the other party.

As well as noise cancelling, some phones also use the two mics to record sound files and videos in stereo.

It depends on the phone, the operating system, and apps installed on it. Older Android phones do not activate the microphone unless it is required by an app (e.g. phone, voice dictation, etc.) Newer phones such as Google's Nexus 5 or Motorola's Moto X for example, have a dedicated low-power audio processing module that can be configured to be always on, ...

Can two apps use the microphone at the same time? As far as I know: By default, the same way two different apps can't use the camera at the same time, the same principle applies to microphone too. Since these hardwares' drivers respond to only one call from one user at a time. Of course you can make an app that gets the input from microphone and then acts ...

My first guess is that your phone has two mics - one for "computer-like" use, one for when you're holding it to your face - and the second of these is broken (i.e. a hardware problem). If that's right, then you should get it repaired, either by taking it back to the shop, or by finding a repair centre near you.

Providing what worked for me, in case someone else has the same problem: A helpful suggestion over at xda-developers.com by developer bilgerryan indicated I should Odin a full stock ROM, in order to replace whatever corrupted data was causing the problem. Long story short, in the process of looking for progressively "fuller" stock ROMs after several ...

Surprisingly I was able to fix this issue in my phone by changing following wi-fi settings: Go to advanced wi-fi setting. You will find a toggle option "Scanning always available". Disable this option. Worked for me.

Sure you can, there's a product that uses the audio port as an extra button, check this: http://gizmodo.com/add-a-button-to-any-android-phone-with-this-genius-head-1221431712 Maybe this is more like a comment than an answer, but actually i can't add comments untill i reach 50 points. By the way, as microphone it's an analog input for the android, you can ...

A USB Microphone as well as any kind of USB Audio device needs a USB host which has drivers for USB Audio devices. Under Win/Mac/Linux these drivers come preinstalled and you can use your USB Audio device in a plug-and-play way. I have experimented with different ways of using USB Audio on Android and this topic seems to be quite diverse. Depending on the ...

I've come up with what is hopefully a better solution. Use the app here. Install the app on both devices. There are many similar apps to this so if this one doesn't work perhaps try another one. The app listed works over Bluetooth rather than WiFi. I hope this is OK and it should avoid latency. I'm not sure why I didn't make the link in my head that what you ...

Yes, there is an Application Camtest Audio. You can use it for streaming audio/video over the network using WI-FI. I uploaded my app for you in this link: http://www.droidbin.com/p1alrjvilfvl31joi1evm1qbilfl3 This app is based on an Open Source library called ["Libstreaming"]

I just found a way to do that. You can use Tasker to automatically start the loudspeaker(which starts using secondary mic.) and then also add a rule to Tasker to reduce the loudspeaker volume to minimum which will very closely simulate the situation.

Microphone and Audio Input are separate inputs. I can see the confusion as they both use 3.5mm Jacks, however Audio Lines require a pre-amp prior to the output side, the pre-amp amps up the raw line to give it volume and this outputs digitally formatted data rather than Analog data. The Microphone on your Android is supposed to be connected directly to a ...

I got exactly the same problem with my Phone(Oneplus 5). I've tried a lot of things software side but nothing helped. Due to my work, my phone was exposed to flour and I got flour in every opening of my phone, therefore also my charging plug didn't work perfectly. So I replaced the charging plug and with it the bottom microphone. Afterward all worked ...

There is no definite solution to your problem AFAIK, but I can share my thoughts on it. From documentation: If your app is running in the background on a device running Android 9... it cannot access the microphone Furthermore since Android 9 you can force an app to use microphone (and other operations) only in foreground: ~$ appops set com.discord ...

Sources of facial detection, on a phone that detects face rests at: /system/vendor/pittpatt/models /system/vendor/pittpatt/recognition I'm using CM13 for my case. They are located there. Maybe facial detection might do that

I'm unsure about Nougat but this works for Android 6.0.1. Run: adb shell dumpsys audio In the output look under Audio Focus stack entries (last is top of stack). E.g., when I had an audio recorder app using microphone, the output was: Audio Focus stack entries (last is top of stack): source:android.os.BinderProxy@a60844c -- pack: com.sonymobile....

Using logcat extreme and monitoring per app set to WhatsApp , it shows mediaFocuscontrol: Audiofocus*request*Audiofocus() from Android.media.audiomanager when microphone is activated And mediaFocuscontrol: Audiofocus*abandon*Audiofocus() from Android.media.audiomanager when microphone is de-activated

Sending strength: Modern digital cellphones are set to utilize the minimum power to maintain a connection. So the fact that the connection isn't dropping completely tells you that you have sufficient RF signal strength to make and receive calls. Talk Volume: As for them telling you that your voice is not loud enough I would suspect the microphone itself. ...

From the following article, it could be due to need for an impedance (a resistor) between the Mic and the Ground wires. As per The trick in detecting the external microphone on the smart phone is to have right impedance between the mic pins. Samsung phones seem to require a microphone with impedance of around 1.0k – 1.5k Ohm. Some other devices ...

A temporary fix is to put it on speaker then back to internal mic I've had this problem with three different phones all different name brands.

OK, so I have an ANSWER. I know for sure that the Pryme BTH-300 can accept a microphone plugged in via 3.5mm and sent the external mic's audio to a device via bluetooth (I have one myself). The only bummer of the Pryme BTH-300 is that the audio output, if you're listening to music, for example, is poor. I'm going to try Sony RM-X7BT which has a ...

Lots of phones have more than one microphone on them. I know for a fact that my Oneplus One has three, and I think your phone has four. If that's the case then it could be a hardware issue. before taking it back do a full reset and see whether that helps. At least then that eliminates the possibility of a software error.

I found two apps one free - Auto speaker here Try the free one first second Tasker - Paid here It has lots of automating features beside your need. Before paying for App Read the tutorial first. To use tasker use this tutorial link Both apps uses sensors. Try on you device.

I think the OP has already bought a converter and is enjoying the MH1, but in case someone else stumbles upon this, I have Xperia Z2 and an old MH1. I use a Sony Ericsson EC250 adapter. Everything on the MH1, including the mic and all four buttons are working fine. The converter is basically a CTIA to OMTP converter for old phones, but those converters work ...

Did you by any chance disable the Google App in your application manager? To find out go to settings>application manager then swipe over past "running apps", "all apps" options until you see a list of "disabled" (or "turned off" on some devices) apps. Look to see if the Google App is deactivated. If it is, click on it and press 'turn on'. I disabled my ...

As to your question: It depends on which apps (or malware) is running in the phone. For instance, when I am in the Google app, it is constantly listening for me to say, "OK, Google" which then takes your utterances and sends the audio to the Google servers where it is decoded and the transcription is sent back to your phone. Whether doing a search or ...

On my Samsung I9300 Galaxy S III with a Android 4.1.2, I use Camera Zoom FX (non-free): it can take pictures without stopping recordings done by Android's native voice recorder (unlike the native camera application).

This is the mic on the Samsung Galaxy S2 And this is another mic on the top. In the user guide it says that it is a "mouthpiece" I presume by that they mean a microphone that is only active when you use the speakerphone feature or record videos or when the user is on a video call.
