Microphone failure only during phone calls - Galaxy S6 Active

Most of my phone calls on this device have been pretty bad.
Most people tell me to turn off handsfree or "Hey! Talk louder!".
I phoned myself on a friend's phone and I herd my voice quite clear and whatsapp audios and recordings work perfectly.
Also when in call plugging in a headset and using the external microphone instantly fixes all problems.
I've made sure I'm not covering any microphone when holding the phone (only one next to charger port right?).
I'm really confused also because I've used 5.1.1 to 7.0 and this problem has persisted indicating it's hardware related.

Try shining a bright light in the hole, look with a magnifying glass. Do you see any junk in there? You ought to be able to see a mesh screen (probably dusty / covered in fuzz). AoN

Put the phone in safe mode and check how the microphone works when you call. If you hear perfectly then it's likely to be a problem in the installed applications that have access to the microphone. Need to understand which application creates a microphone problem?
Did you install the same applications after upgrading to android 7 beta that you installed on android 6.01?
Rather yes, since I also did this, but it turned out that some program interferes with the microphone. I had to reconsider the installed applications and to cancel the permissions to access the microphone.
At me the given problem has disappeared ...

I don't think it's dust in the mcrophone since this happens since day one
I'll give this a shot tomorrow! I don't have many apps but I do have some indispensable that may have interfered with the microphone.
I'll report when I have someone I can try this with. Thanks for the tip!

[Q] Problem with speaker and microphone.

I'm running the latest version of SlimLP on 5.1.1. The issue also happens on stock firmware too. Here are the problems:
1. The speaker doesn't work, except extremely rare circumstances when I hear a notification, usually from FB Messenger.
2. The microphone doesn't pick my voice up during calls, forcing me to use an integrated mic on headphones or loudspeaker.
3. The earspeaker doesn't seem to work.
4. When I record video or something, the sound is picked up, so obviously the microphone is still functional.
I've used the Xperia diagnostics app, and the microphone isn't deemed functional on that, the ear speaker doesn't work at all, but the loudspeaker works perfectly fine. I really don't know what to do. I don't think this is a hardware issue with any of them except the earspeaker. Anyone know fixes? I've tried pressing down on the areas but that doesn't seem to have an effect.

I also had a similar issue on another Xperia and I simply changed my firmware. Most likely I must have downgraded it. However, there is an app called SOUND ABOUT
That should fix the sound problems. Quote back in case you expect a reply!

I've tried the app before, it didn't work, now it does! Thank God, I'm pretty damn happy about this. Bought the pro licence.
When I plug my headphones in however, sound keeps coming out the normal speaker, rather then the headphones. Hmm.

Trust me this is a pure software issue. I had such problems with my device once. Sometimes plugging in and plugging out head phones a few times fixes it as well.
Have you tried going back to stock ?

Microphone doesn't work

Hey folks,
I had the problem with the stock ROM and now I have the similar problem with jackeagels 5.5.1 (SM-G800F).
My microphone works sometimes and sometimes doesn't. People I want to call can't hear me. Eventually after a few calls they do. This is a state I don't want to stay in so does one has any idea what the problem could be? A while ago I pulled some dust out of the mic hole (with a needle) but that doesn't seem to be the problem here
Mines always been dust in the hole. Get compressed air can and blast it. Very annoying.
Hey Guys!
I have a similar problem but only when I use the internal mic, the problem does not occur when I use my headset.
Sometimes, the people I'm calling say that they can hear me very quietly.
Mostly, they say that they hear a constant noise or sound like a "bom bom bom" which is in the background. I can't hear this sound myself and as I said it does not occur when the headset is plugged in.
Any help is appreciated!
Regards, Jens
What phone model? What OS?
The main mic is at the bottom, near USB port. Recording a voice note without earphone, of course, works? The mic hole is dirt or blocked somehow?

Thanks for your reply.
It is a G800F with CyanogenMod 13.
I tested the issue after my initial post with the voice recorder in detail.
So the sound is a kind of buzzing like in the early days of mobile phones when you put your phone near a radio and you get an incoming call.
When I record with the voice recorder, then I hear the buzzing. It is stronger when I say something and quiter when I record silence. Then I also made the same test with my headset, and, unfortunately the buzzing also occured. The intensity was bit lower I think but the sound was there.
Unfortunately, I never tested it with the stock rom. Could this problem be related to a software problem? I'm not sure if I backup my CM and install a stock rom for testing...
Thx!
Yeah, the best way to mak sure it's not software is backup and going back to stock. If it still doesn't work then you have a hardware issue almost certainly...

Microphone not working in call. Please help.. :(

Suddenly my Microphone not working in call. People at the other end can't hear me at all (both normal or in speaker phone). However if I use wired headset or Bluetooth headset in call the everything is fine.It was working fine (I was at CF Rom sutl44 with exposed) then it suddenly stop working since a week ago.
My phone is Verizon Droid Turbo XT1254 bootloader unlocked with sunshine.
At first I thought that maybe my mic is dead but it is not. The voice recorder app (Hi-Q MP3 recorder) can still record from the mics without problem.
I read a lot of this issue and mostly because of software problem, so I tried all that I can think of.
I have reset my phone, even do a full wipe and start clean install but the problem still same.
I flash full stock odexed firmware (sutl44 or 49) with same result.
I flashed resurrection remix rom (the latest) still same problem.
I changed build prop as per some people suggest but still same problem.
From the hardware side, I disassembled my phone and clean mic holes, check mics condition, all seems fine. When I tried using the voice recorder it can register any sound or even touch so the mics are working and sensitive.
FYI, this phone has 5 mics, I checked and tested (with voice recording) them when I disassembled the phone. All are working fine.
I'm really desperate right now.. I love this phone and this is my main phone. I will appreciate any help or suggestions.
Maybe some ROM recommendation that may fix the mics problem.
I just flashed RR Marshmallow to see if I get any luck but unfortunately no.. mic still not working in call.
I tried to remember when this problem start to happen.. I guess it was after I install GravityBox in Xposed and start played around with the GB settings.
I have TWRP backup before I install that GB, I tried to restore the backup but still mic not working in call.
Did Xposed can change something very basic (like a 'driver' in windows) that can't be changed back by re-flash or load a TWRP backup?
Because somehow I think that this 'driver' or 'library' for mic in call is bad or gone.
Please.. any suggestion?
This might be a long shot, but I just had the same issue. After making a call using Google Hangouts, it started working again for me.

tertiary
Remove your tertiary microphone. It is the lower right when looking at the back. After this you must ground your audio output pin or you will get buzzing sound during recordings and conversation. This pin will be lower left out of the four where microphone was removed, there will be a chevron shape beside it which is a convenient ground location. This problem as far as I can tell happened after a security update from Verizon. I realize this sounds like a bogus fix but it made my phone work GREAT. This microphone is picking up your voice as well as the main mic and causing noise reduction to the point of no audio.

Since it's a software based issue, flashing a ROM different from stock firmware wouldn't fix it? He said he tried flashing Resurrection Remix.
BHB27 kernel's problem
I don't read your post carefully, so I don't know if your ROM and kernel is same to me, but I have similar problem in last few days. Finally, I find the problem is the custom kernel, the lastest BHB27 kernel, when I flash the old version custom kernel, the problem is solved. I hope this information can help you.
My ROM: http://forum.xda-developers.com/droid-turbo/development/rom-mpg24-107-70-2-brazilian-6-0-1-t3426234
Kernel: http://forum.xda-developers.com/moto-maxx/development/kernel-bhb27-kernel-t3207526
The new kernels have problem, so I flash back to BHB27-Kernel-V201-8-M.zip
i was able to solve the issue by plugging in a headset and then unplugging it. sometimes some dirt/junk get stuck in there, and the phone thinks that it is plugged in, thus muting audio out except through the jack.
I have the same problem, you fixed this problem in your phone?
I try RR (Android L, M and N), CRDROID (Android N) and NX (Android M). In all of this ROMs, I have the same problem.

can you give more details about the problem that you faced?
After nougat update in Moto M mic not working.
I was not ready to do a factory reset. But there is no other option to fix mic issue after nougat update.
So, last night kept back up of all important folder and run factory reset without automatic restore.
Now, everything looks fine to me. Incoming and outgoing calls are working fine.
So, I am suggesting everyone to do a factory reset, this is one and only option to fix mic issue.
Thanks,

help mic.

help,
all of a sudden my mic on the phone is crap, i havnt droped it on the floor or anythiing like that.
but today it startet to make a very loud noise so the reciever of call couldnt hear a thing, tryed to restart the phone, it helped but only briefly,
is it a general problem?
or im just unlucky
regards
Hey man,
I just registered to say that I have the same problem. I own Nokia 8 and sometimes when I call with people they cant hear me at all or they can but they hear a loud noise. It looks like it is randomly occuring, I can call the same person 5 minutes later and they can hear me loud and clear all of a sudden.
Its very strange I think its the problem with microphone and I think its software related because I believe camera is using the same microphone for recording and that seems to be fine whenever I record a video.
Messenger/Viber/Whatsapp voice messages doesnt work sometimes tho so its linked. Hopefully this can be solved with via future updates but we should let Nokia know so they can sort this out.

Well in my case its much worse, I bought it from a guy who won it in a Facebook contest from Nokia that was held back in September I think. I am not sure if warranty applies to my phone, I hope so. But even if it did I would have to send it to UK and I am from different country

Tell them that it might be a software issue on Nokia end so I dont think they can do anything with it other than give you a new device.
same here
I found the same here. It is like interference. Since there are 3 mics, is it possible to disable one for testing?
Same here, happened today for the second time! BT and speakerphone modes are not affected, and only calls are affected - recording through an app does not produce the same issue. It's like someone is blowing air with full force into the mic!

Exactly like you describe, blowing air with full force into the mic.
But recently the problem somehow stopped and the mic is working BUT he audio is still damaged I believe because when I record a video there is interference in the background and no way its the same quality as advertised with OZO audio.
I also noticed that it stopped working after CHARGING the phone everytime, so I had to restart it after every charge, so maybe problem with electricty damaging the microphone ?

I have no idea what to do, will have to trash the phone for something else. It's still not working after hours of troubleshooting.
I managed to restore the mic functionality by entering safe mode (by pressing volume down during power up). We'll see how long will it last.
It's back. Nokia never again.

Nokia 8 Oreo. EDIT Ok found the thread - it Was specifically about Receiving calls, but might apply.
SEARCH xda nokia 8 questions & answers speakerphone
First question was 12 march 2018
Possible solutions:- 1 Full factory reset, setup Google account, don't install apps and Try it to see if solved.
2 Use Macrodroid app to turn off speakerphone 1 to 2 seconds into call (wow great app)
3 Press speakerphone icon twice at start of each call
4 Oreo 8.1 seems to have the problem less
Hope This Helps
I think I have solved this problem with my Nokia 8 which had been persistent for the last week.
I just took a household vacuum cleaner and cleaned out all the microphone slots and bingo the problem was solved!
Unfortunately I can't log in to the Nokia community forum to post there, I just get three endlessly pulsating dots, so if anyone can copy and paste this post over there it would be great.
Bad Mike.
I faced the same after last security upgrade. Today it became an issue for ANY call. And nothing I tried/found helped. (Soft resets, charging, Safe mode). Nokia 8 just generated noise like I would be staying on windy hill.
I've contacted Nokia via the Care app. It tooke ONE HOUR but in the end the operator helped me and I hope I've explained they should at least respond on their forum when the issue is reported almost a year. And their developers should know about issue that prevents using of phone for calling.
So the what worked for me part of answer:
- Settings>>Apps&notif>>See all apps>>Phone>>Storage>>Clear cache and Clear data
- Settings>>Apps&notif>>See all apps>>Carrier Services>>Storage>>Clear cache and Clear data
- perform soft restart (Power + Up buttons for 10 secs untill you see powered by Android)
Even before performing of the soft restart it worked again but it should be better to make it as well.
The microphone problem happened to me for the second time yesterday in a couple months. I tried the following, and it did NOT help. That said, the microphone returned to normal later in the day - it seemed to coincide with battery saver kicking as the battery become low.
I wish it would fail hard, so at least I can easily warranty the phone. At present, just when I give up and think about claiming warranty, the phone works again.

I am having problem with recording voice message with WhatsApp and any other voice recording apps.
I did everything and Nokia support member said it can be because of last security patch.
I can make calls and no problem but when I wanted to send voice message no success.
Please help me
Mine has been having the same problem for about a month now, had to start using my earphones for calls.
Using Google camera to record the audio is perfectly find, but stock camera and dialer have this noise.
None of the above has helped.
Considering sending it to the Nokia phone repair?

Help with sound issue

Hope somebody can help please? My Zuk Z2 Pro has lost the earpiece sound when on a phone call. People can hear me, but I cannot hear them. I am sure its a software problem but not sure how to permanently fix it.
I ran a manual engineering test by typing *#*#1111#*#* and checked the speaker and the microphone in settings, they are fine. However, the ‘Rec’ setting wont play any sound to the earpiece.
I have read its a known issue and installing the app mswitch (keycut) worked,but it didnt. I then read about switching off "OK Google", well on a Zuk this is not easy to find, so am not even sure I was able to disable this app.
EDIT: After more investigation I have found that when I turn the voice volume up in ringer settings it does nothing, which I think may be the speaker itself. My wife has the same phone and hers works normally. There are three ringer volumes, and the middle one does nothing but I know it did yesterday
I then tried another app called "Soundabout". This worked and allowed the Rec setting in the engineering side of the phone to play a sound, like an increasing oscillalation of sound. I then restarted the phone and it worked, but not permanently. The app doesn't seem to stay working.
However, when I made a phone call the earpiece speaker still didnt work. I could not hear anybody but they could hear me.
However, it does work when headphones are plugged in.
Does anyone know if a factory reset of the software would help as I am stuck and desperate for help. It just suddenly stopped working yesterday, so am puzzled as to why. The phone is just less than 12 months old, so not particular aged and it has always been in a case and well looked after. Its running stock Android 6 with the ZUI overlay from Zuk, so no changes made to it.
I have de same problem. Two months ago the speakers decreased the volume and microphone does not work properly.
I replaced the usb + mic piece, but the problem remains the same. Now, I have ordered speakers piece, but I guess the problem will continue.
The only thing I can think is the origin of the issue could be the bluetooth earphones that in some way had changed the sound configuration.
Try to qfil ZUI 1.9, if that does ot help then its hardware problem most likely.

Finally I have found the origin of the problem. It was in the dust filters of the phone. I used an special liquid for the screen protector. Some of this liquid goes to the filters. I have cleaned this filter with a brush teeth.
It is silly and I feel dumb.
Simple fix
Please do not feel dumb or stupid as this is something we don't think about.
The problem is due to dust and fabric accumulation. I just had this problem.
The fix is simple.
Use something soft to bang your receiver. In my case i used the tip of my finger. You want to the bang to be good but not to break the glass. My finger hurts a bit so I think a small rubber hammer will do the job.
Hope this helps.
Clean earpiece protector
Hi, I had the same issue and after trying all software tweaks with no success, what I have done is use a toothbrush to clean the tiny holes from the earpiece protector. I pushed some brush bristles gently through the holes and... it worked!!!
Hope it helps.
