troubleshooting of everyone calling me hearing an echo - OnePlus 3 Guides, News, & Discussion

Hi! I have successfully conducted troubleshooting of everyone calling me hearing an echo of themselves!
Turns out, there appear to be two settings for microphone detection.
1st when it's uncovered, and the communications are nornal and working well
2nd where it's covered, and the detection is amplified to still hear the op3 user same as before
Problem with the second is, that it detects sound from upper part of the phone, so the other party hears themselves.
In my opinion, the lower limit of detection switching it into 2nd option is too high, because even when uncovered it happens sometimes in bad conditions, far more using phone cover (yes it has microphone uncovered, but there is noticeable difference).
If possible, that limit should be lowered, or the function altered because this echo isn't something a phone of this rank should have.
*I've only assumed how it works by observation, there may even be a curve? That could also be altered. Anyways, it really is an urgent fix in my opinion, I don't know about the rest of you.
To reproduce it, remove cover, take two phones, and call the second phone. Listen to second phone, and cover/uncover microohone on op3.
It happens on stock software or any other rom/framework I've tried so far.
I'm not a phone developer myself, but hope someone can work with this.
Regards, JerryBond

Being a stock issue in hopes of being noticed before the P release and possibly being fixed there, if it's too deep to be fixed in earlier versions? I'm not an expert, but rather safe than sorry, no?

No, you should report IT with oneplus itsself.

in-call static/interference/resonance/noise problem

Hi guys,
i think there's a problem in my i9000;
whenever i make a call, i can hear low static interference in the background.
i searched both on xda and elsewhere, and although some other people complained of this problem, no one was able to determine the cause or provide a solution.
i tried different roms, froyo and gingerbread samsung roms, in addition to cm7, with different kernels and modems, heck i even changed my csc(just for sake of changing everything to make sure.. all for nothing. the problem persists.
Does anyone know what might cause such problem and how it may be solved?
i have exactly the same problem. Like you; i tried every combination which i can. I think main cause of the problem is hardware related. But my opinion is ,it can be fixed with device drivers. I looked at service manual. In the speaker part of the service manual,you can see there are two inductors and one capacitor before the speaker module. You can see the full circuit in Service Manual Page 42.
h**p://img191.imageshack.us/img191/2383/speakerj.jpg
I think these inductors(L209,L210) are interferencing with the GSM frequencies and making that static sounds on the background.
We need someone who is an expert on linux and device drivers. Maybe he can show us to find a way to break this circuit(temporarily turn off B1 and A2 pins) in a call so it will not make that sounds.
In the other hand we may have defect phones. May be the only way is to change some parts.
sorry for my bad english.
I think there's something wrong with the speaker itself.
I'm taking the phone to samsung's maintenance to see what they have to say about it.
I'll report back once i get to the bottom of this..
Same here, but it's not constant, just happens enough to be noticable, bloody annoying, and only started (or I only noticed it) a couple of days after JVP. Will be interesting to see what you find out...
One possibility, do you have your phone in a magnetic flip case? Worth checking

No magnetic flip case, just a hybrid (plastic back+sillicon frame) cover.
I even took it off for a while to see if it was causing the problem, but no.
I went to samsung service center and they said it will cost about 200$ because the ear piece comes with the touchscreen..
Meaning i would have to pay for a new touchscreen even though i only need the ear piece.. How about that for service.
I checked ebay and found the whole ear piece+speakerphone+headphone jack in one bundle for 15$
so guess what my next step will be??
Buy and install the ebay part, sell my i9000(never liked tw anyway+cm seems a long way from home).. Had enough samsung for one lifetime
are you sure about the sound is coming from the earpiece ? i am asking because few weeks ago i was also assuming that the interference sound is coming from the earpiece . But i realized that it is coming from the rear speaker. Can you test it ?. In a call ,turn back the phone and put speaker hole to your ear. The interference sound is so loud that you can hear it from the earpiece hole.

This is the question which i am also looking for answers
Everyday i am searching for answers. Only a very few people experiencing this problem.
I think this problem is coming from the inductors in the speaker circuit part. You can look my first post .

i have this problem too, i live in Romania, i tough my phone was broken, but a friend's phone also does that.
i notice it when making call while 3G data was running in the background. If 3g is off = no noise.
Also i have noticed, the way you hold the phone affects it. try holding it with 3 fingers to your head the covering the mic hole with the other. you should hear some interference right there. so it's probably: speaker+ extra sensitive mic + some antenna things
Also my friend had the phone for some months now and never noticed it i searched the web and we're not alone, i found this discussion on a couple of other forums, still nothing to do, or nobody reported back after they whet to the warranty service. i would go, but i don't have any warranty on mine.
I'm also from Romania and I noticed this annoying issue today. All my other friend with Galaxy S also have this problem, so I guess it's a normal thing.
The only solution, I guess, is to use 3G networks, at the risk of draining a bit more battery.
so bottom line is that on mine, i hear noise/buzzing/interference when i use 3g networks both on the speaker on the back and the earpiece (it's louder if i use 3g data while i'm making a call) - the issues goes away completely in gms(2 g) mode
and it depend on how i'm holding it - it's louder if i grip the phone in my hand (probably the wireless signal is lower and the phone increases the power needed to communicate to the network thus experiencing buzzing sound from the speakers like radios did back with the first cell phones before receiving a call)
so i guess i'm not the only one, right?
This issue is normal I think. No big deal. If the noise however gets so loud that it interferes with your call, get it changed. But the new ones you get might have the noises too. So what is important here is to keep the noise to the minimum.
With / Without the noise is totally an unknown cause now. At least have it settled to the least noisy.
*This is happening to everyone who is getting the phone since November 2010
I confirm this issue with more models.
Hi guys!
Bought myself my GT-S5570 (Galaxy Mini) a couple of months ago. This is my first Android experience. At first I was pleased, but then I noticed this static noise whilst in call. It's like, suddenly I can have ill-isch, distorted, "noise spikes" sort of things. Left my phone in for service under warranty. When I had it back, it was still messy. Bought myself a GT-5660 (Galaxy Gio) a week ago, thinking that this one would clear the issue. It's still there, though. I'm wondering if this is something that affects the whole Galaxy series, even the tougher models like S/S2.
Related threads, by me:
android.net/forum/samsung-galaxy-mini/60951-sudden-volume-spike-during-call.html
androidforums.com/samsung-galaxy-s/307523-samsung-galaxy-s-gt-i9000-static-ear.html
yesterday my cousin bought i9000 too. First of all i looked for the noise. It is interesting that that phone is nearly noise free. If i gave 10 point noise to my i9000 than that phone will be 2 points. You can hardly hear the noise. After that i get her SIM card and test my phone with that sim card.Noise is still there.I make that phone software same with my phone. That phone still has no noise.
I think the problem is in phone parts. Maybe a defected series of speakers used in our phones. I will buy a new speaker module on internet. I hope that fix my problem.
For me it depends more of the network I use than the phone. It happens sometime with an iPhone.
as i stated in my previous post in this thread, in my case i was sure it was the loud-speaker, i say "was" because i sold the phone, and thats the reason why i didn't come back to this thread since..
it seems there was something wrong with the loudspeaker(on the back of the phone), and it was, at least to me, one of those things where a person might not really notice unless you're looking for it.. my bad luck had caused me to flash a certain modem and the reception was bad, so once i reverted to the previous modem i was checking for the sound clarity and that was when i first noticed the static during calls..
then i realized it was coming from the speaker, as one good man in this thread suggested. i couldn't handle it though, i could hear it every time i make a call..
it didn't make a difference whether i was on 3g or gsm or both, it was always there, unless i went into airplane mode..
so i ended up selling the phone, and bought another, but before i had bought it i put my sim inside and made sure there was no static, and there isn't, whatsoever.. thank god.
i'm sorry i couldn't find any other solution to the problem, samsung service here had said they would replace the speaker, as the part comes on its own, unlike the case for the phone speaker, which, according to samsung, is bundled with the screen, and if i had wanted to change it i would have had to pay something like 200$ to fix...
those who have this problem, check if its the loudspeaker on the back of the phone is the actual culprit, and if it is, try to find a way to replace it or something, that is if it bothers you this much. or you can just sell the phone, there's a 99% chance those who buy it won't notice anything, because they're not looking for it..
good luck guys..

[Q] Ever sound Distant, Quiet or Muffled? See if you can replicate my findings...

UPDATE: Sept, 23rd, 2013: I gave in a week ago and replaced my phone with a re-manufactured one per the suggestion of another rep. Was hesitant since I was doubtful it would solve the problem, nor did I want any NEW issues. Well, the replacement phone seems fine, except it still has the same microphone issue. A caller this weekend who hadn't actually experienced this problem with me before was very confused while talking to me... "hello? hello? You sound far away."

Work Around 1: My personal work around so far is to hold phone steady, don't move it, and talk very evenly (no changes in volume). Occasionally have people unable to hear me, but my satisfaction with the phone has gone up now that I can control the problem more.

Important Note: If the noise cancellation mic (top back of phone) hears your voice clearly, it may think you are background noise! Once you're registered as background noise, you'll have to be patient and wait 10-15 seconds for the phone to reset. Talking louder will lengthen the problem. Resist the urge, and speak at a normal volume until the caller can hear you again.

I've had numerous people say I sound "distant", "muffled" or "very quiet" from time to time. It doesn't happen a lot and has been hard to track down. I now know it's not location, or signal related. The "pinky finger over mic" idea is brilliant, but I've been holding my phone with as minimal contact as possible since reading about the signal deathgrip issue to rule that one out too.
I even just called HTC on my ONE to report the problem and it started doing it. The girl couldn't believe what she was hearing.
Unfortunately, they couldn't replicate it in their offices immediately.
After some thinking, I can reproduce this problem any time now and wanted to see if anyone else could as well.
I think it is related to the dynamic MIC gain not resetting quickly enough, if at all.
Call someone and just start talking normally for a few sentences.
Turn the phone so the bottom edge (where the microUSB + MIC are) are pointing straight towards your mouth.
Speak a couple more sentences. (You may need to get it close to your mouth, you may need to speak slightly elevated to trigger the issue... But don't SCREAM AT THE PHONE; it seems to be smart enough to not be affected by this)
Revert phone to normal talking position and continue conversation.
When I do this... the other person cannot hear or make out what I'm saying for 10-15 seconds. Now obviously this seems stupid right? Who talks this way? Well, how do you talk to someone when you're looking something up on your phone during a call?
The real gotcha is that it happens to me when I'm just in a plain conversation. My thinking on that is maybe I coughed, or laughed loudly for a sec, or just accidentally moved the phone closer than I should have since I don't tend to sit like a statue when I'm in a call.
Let me know what you get, hopefully I can rule out personal phone defect vs. issue for HTC to look into for all of us.
Dude... you might have hit the nail on the head. I have exact same feedback from people.. they say "Are you there..? Can you ehar me.. " all of a sudden in the middle of a conversation. I will try this now with someone I know.. me being on the HTC One.
This is the ONLY thing bugging me. Hopefully I can replicate this.
This was basically my theory in the thread I started in General. I have a feeling that it is over-aggressive in its low-cut trying to get rid of background noise. So far since I swapped phones yesterday, I haven't had any complaints. I had a DEFINITE issue and it wasn't the pinky for me either.
Wonder if it's something that can be fixed in software.

I'm glad it's not just me! It's frustrating especially during business calls, or conversations with older family members. Times when you really really need the phone to just work.
I've used Google Voice on another phone to call into and have made perfect MP3 recordings of this problem and already sent them to HTC. I can trigger this issue now on demand no problem by doing the above.

Excellent characterization of it, perhaps even badass, if I may.
Let me know if you still have the problem on your new phone by doing my test above with someone when you can. It's so easy to do. Just have a conversation and in the middle of it, turn the bottom mic to your mouth and talk just a little more loudly... then resume conversation. Guaranteed issue here on my phone.
And like I said, for anyone else passing by this thread... I know I'm sort of forcing the phone to have an issue by doing this, but it's just an easy way to show what has been happening to those of us with the problem during normal day-to-day conversations.
Once it happens, the louder you talk actually will make it worse. My only cure is to be silent and wait for it to "cool off" the processing it is doing. Again, not easy to do if your recipient isn't understanding.
I get the same comments from people too. They say it sounds like I talk away from the phone randomly, or cant hear what I am saying correctly. Funny thing is that when I was force roaming on verizon I never had one complaint about that. The first phone call after switching back to a sprint prl I had that complaint. So who knows
Ihave been having this problem as well. Was thinking about trying to exchange phone, but I was wondering if you ha e heard anything from HTC after reporting the issue

I've sent them three audio samples to a special email they gave me for one of their upper tiers who wanted to look at this case specifically.
I'm able to make it happen with excellent signal, etc. and can do it every time now just by temporarily talking a little louder by turning the MIC towards my mouth.
No HTC response as of yet. Recordings were sent in 3 days ago. I'll update here as we move forward.

Nada thing yet. I can still do it on demand no problem and still have people occasionally tell me they suddenly can't hear me.
I just called to check up and was told that I in fact, will be getting a call from the escalation team soon according to the notes on the ticket and they'll talk to me about my findings and may ask me to reproduce it on the fly. Obviously, I'll provide all info I learn back here.
I see...my 14 day return period was ending so I'm gonna just exchange the phone. I bought online so shipping is a bit of an ordeal.
Question, are you using an Airave by any chance? I make most of my calls off one, and haven't noticed the problem outside of using it with the Airave - altho it is a much smaller sample size. I'm wondering if this has anything to do with it. I'm also usually on WiFi when this happens.

Never been on an airave. I've tried in 3G areas, 4G areas, with WIFI on, with WIFI off, toggling between CDMA only and CDMA/LTE. I've had the issue in varying degrees of excellent signal and just average. I can also produce the effect (although it's not as drastic) with just using the voice recorder app.
Not that all of these make a difference, but just trying to be helpful so you know my exact situation. Let me know if after exchanging you see any improvement! I assume you're able to reproduce what I've done above with your current phone?
Update: Disappointing so far. I didn't get a call from the tech, but spoke to someone else after I received notification in an HTC Ticket. The new rep asked lots of questions, some relating to the problem, some not... he said he'd talk to the other tech (to whom I sent my audio samples) and would get back to me.

Not sure if my issue is related, but randomly on a call, usually a couple minutes in, I start getting severely choppy audio both in and out like nearly every other word is being dropped. This has happened while on a Airrave, in my car, and just standing in a parking lot.
I'm not seeing others with this exact issue but maybe someone can chime in as well? Might be I just got a lemon from a launch day pickup.

That's awesome, thank you, I had missed it.
To update everyone else on this thread, we're moving along and I sent them audio samples recorded from the other person's end (recipient).
Seems like we are beginning to lean towards the noise cancellation mic on the back occasionally picking up your voice while in a call, and then the phone filtering your voice out, inadvertently thinking YOU are background noise. The frequency cut would make you sound far away, or like in a tunnel.
Makes sense and it may be randomly happening during a call when you switch ears, look something up on your phone, maybe turn your phone to let someone else speak with you on the phone for a moment, etc. and the mic on the back of the phone picks you up (these are personal theories).
My personal work around so far is to hold phone steady, don't move it, and talk very evenly (no changes in volume). Occasionally have people unable to hear me, but my satisfaction with the phone has gone up now that I can control the problem more.
I noticed muffled call quality as well and think it might be a defect. I noticed an issue also when I tried testing out the video quality and recorded a song playing from my stereo system. After recording it, I noticed almost all of the sound was on the left channel, and the right channel was almost non-existent. I uploaded the video to my computer to hear it and noticed the same issue - the left earphone was loud and clear, the right was very quiet.
Do those of you who have call quality issues also notice microphone issues during video recordings?

I'm having the same problems.....call recipients complain of my voice going in and out. I originally thought it was a defective mic. However, when I tried to record my voice like jpzsports, both left and right channels produced clear sound. I've also tried covering both rear and front mics while recording my voice...the muffled sound only occurs when I cover the front mic (which would be expected).
I'm leaning towards lauski's theory. It does seem to be some type of defective noise cancellation software that chooses to actively cut out my voice. At least, that's the only thing that would make sense if the mic seems to be functioning properly.
Let me know if you guys figure anything else out!
I can replicate the problem all the time by holding the phone with my shoulder instead of my hand. I thought it was my otterbox or I was blocking a Mic but I'm not...Hope a SW update fixes it.
Btw it's my left shoulder pressed against my ear.

[Q] strange electric buzzing Noice from top speaker

Hello,
This might be a double post, but nevertheless I have noticed a strange buzzing noice from the top speaker. It seems to occur when i switch wifi off and then on. At that moment when it is receiving and sending data. It seems that the speaker comes on and creates it. If i have to discribe it i would say it sounds like electrical currence or a something shortcutting. Anyone else with this problem? I mailed my provider today and i am looking to send my device back soon.
Also, offtopic, i noticed that the screen isnt positioned properly, on the left side it sticks out...
For me two reasons to look for a replacement nexus 6.
Regards,
Elroy
I'm on my second phone and I'm noticing this too. Its fairly quiet, but in a quiet room it becomes very noticeable. It seems worse for me when the CPU is really going. Also, if I turn off and on the screen it gets louder. I actually noticed this issue with my first phone too, but I returned that due to a camera issue. It might just be interference from the CPU getting into the speaker. Not sure if returning it will help. Sucks this phone costs so much but we gotta deal with issues like this.
We have so many this speaker related issue. plz search.
Don't waste your time replacing the phone because all has it. It's more likely either SW can fix or just a pure dumb HW design by Motorola.

[Q] Others can't hear me

Bought Xperia Z3C and from the first day some calls didn't work well... Others couldn't hear me about 60-70% of the calls, sometimes they heard like strong wind is blowing into the mic and when I put the call on loudspeaker then it worked, they heard me loud and clear.
So I took the phone back and ordered a new one, cause I really like Z3C, even more, if it would work with no problems
So my new, second Z3C, same green beauty - but same problem! I tried repairing with the first phone and tried doing the tests, neither helped. Only this time about half of the calls act like that. Sometimes if I put the call on speaker and then back, it works again, but not always.
So my question would be - Has anyone else had this kind of problem? And if so, what did You do? Is there even anything to do? Is it hardware or software?
There is no other phone I would like but it would be silly for me to try the same thing third time.
sorry to hear that,i guess that when you take the calls ,you cover the loudspeaker at the bottom of the phone
Sent from my D5833 using XDA Free mobile app
Similar thing happened to me, I had to yell first few days untill I discovered I had a bad habit from old mobile phone.
When i talk and holding the phone, my thumb is on the one side, three fingers on the other side, but that little finger is on the bottom, like i hold the phone not to slip down.
And the mic is positioned exactly so my little finger would cover it. That was my reason people couldn't hear me.
I doubt it's your case, but try to see if you do the same thing
Agree with others -- the mic is in a slightly odd place and I had to adjust the way I hold the phone to avoid blocking it in some way. Aren't the mics usually on the bottom left instead of the bottom right like the Z3c?
exact same problem

Bought Xperia Z3C and from the first day some calls didn't work well... Others couldn't hear me about 60-70% of the calls, sometimes they heard like strong wind is blowing into the mic and when I put the call on loudspeaker then it worked, they heard me loud and clear.
So I took the phone back and ordered a new one, cause I really like Z3C, even more, if it would work with no problems
So my new, second Z3C, same green beauty - but same problem! I tried repairing with the first phone and tried doing the tests, neither helped. Only this time about half of the calls act like that. Sometimes if I put the call on speaker and then back, it works again, but not always.
----
I have the same problem in All voice communication apps and normal calls.
If i test the microphone at The built in test i get no problem but in skype, Facebook and All other things that uses my Mic it cuts off and makes a windy sound. I was allmost ripping my own head off in anger and confusion because everybody i call is making me say things 5 - 10 times. And now i see im not the only one... What to do? Great phone beside that and headphone and aux volume is adjusting it self..

So my question would be - Has anyone else had this kind of problem? And if so, what did You do? Is there even anything to do? Is it hardware or software?
There is no other phone I would like but it would be silly for me to try the same thing third time.

I had this kind of a problem on the latest firmware (.77) sometimes. How about you try downgrading to an older firmware? Like the .93 firmware which can also be rooted
Sent from my D5833 using XDA Free mobile app
Got the same problem. After disabling "noise cancellation" (not sure how it's named in English FW) in settings > Call problems is resolved.
But now everyone hears everything within range of the main mic and thats not cool.
Can anyone confirm its related to 23.0.1.A.5.77 Firmware?
On previous version didn't had any issues except phone went underwater and died, and new one is already on the newest fw ;/
Don't want to do root due to guarantee issues after this.

+1 the same issue,
serviceman flushed the original firmware twice
nothing helped, they even refused to refund saying that they can not identify the problem .
Farewell guaranty, I'll try CM mb that will help.
The problem is floating, suspect bad mic contact or bad capacitor installed.
both require disassembling for proof.
Service tests shows that mic is ok.
Does anyone know how to get voltage\capacity curves from mic without disassembling ? mb some test pins on the back ?

Do you can tell what is the sound recorded by 2nd mic? Mine is very low, like almost subwoofer
And on what Firmware you are?

I had this problem, people did not understand what I said, TrackID was struggling to identify music. I left a message on my mailbox and could barely hear, changing the phone position helped a bit but it was still not loud. Sent the phone in repair and now it's perfect, I can whisper and people understand me

You had issues with the main mic - I do not have (luckilly) such an issue. Only 2nd has some problems, but if I launch service tests it records sounds fine. With different quality than 1st mic but records properly.
Mine was recording fine in service tests also (replay sounded ok), but it was apparently not sufficient in calls. I think the service test is very sensitive, with my repaired unit I can whisper at 10 cm and still perfectly understand on the recording.

Please post reply to those questions:
1. Do you have enabled noise-cancelling function.
2. Which mic you test in service menu?

1) Tried both, no difference
2) Tested microphone
Microphone in Z3C is the worst part of the phone
Im also have problems, or people Im talking to via phone, cause previous phone which I still have - SGS 5 mini - has very sensitive mic.
Both my phones are watter proof, also has special membrane, but when Im callling one to another difference are HUGE.
I checked 2 phones of my friends, and thier Z3C's have the same sensitivity, but the dont complain, as suppose they are usualy yelling
In SGS5mini I can rotate phone around the ear and still very louldy and clearly someone can hear me, thera are little diffrences ofcourse, but in Z3C where even when Im trying to have microphone close to mouth sound is much quieter - moving the phone little bit and conversation can be irritating.
It already pissed me off 3 times so much that I ended conversation, because of complaining of the other people.
P.S. Before someone will ask - yes, I disabled noise cancelling function from the begining, also trying different sound settings in call and sound menu.
SOLVED - at least in my case
What I did till today was:
disable any sound "improvements" in menu
cleaning microphone hole with compressed air
After test I saw little improvement, but still I was merely heard by other caller.
Looking mixer_paths.xml tried few times changing parameters and found the right one to rise sensitivity of internal mic.
Below are unchanged section that I'm talking about - in bold specific value that we can rise.
Code:
<path name="handset-mic">
<path name="adc4" />
<!-- 67 % of 124 (range 0 - 124) Register: 0x231 -->
<ctl name="DEC3 Volume" value="[B]83[/B]" />
<!-- 63 % of 19 (range 0 - 19) Register: 0x15F -->
<ctl name="ADC4 Volume" value="12" />
</path>
I choose value=92 as this found to be still safe (don't use to high values as it can damage your device) and I'm pretty happy now of my Z3C
Prepared MOD for this change to apply from recovery.
I've sent mine for repair. They said everything is ok, since repair service does not test calling in real life - just service tests, where this issue is impossible to catch. Had to ask them for "special" test - calling from my phone to somebody, and checking the difference between Noice cancelling feature turned on and off.
Hi any mod for stock ?
My wife have z3c everything was fine just one day start cut off world etc.
Will try with disabled reduce noise option
Any other solution ?
Guys I had the same problem, solved it today
Mine was running latest android 5.0.2(23.1.A.1.28) Z3 compact.
In my Music application(Walkman app updated to Music)-settings-Audio Settings- Mic sensitivity set to High.
Other person can hear me crystal clear
I suspect this is a Bluetooth related issue. I have my Bluetooth always on and when driving and calling there is no issue on car kit. I found an workaround, when calling before connected I press loudspeaker and mute unmute

Question S21 Ultra Microphone Background Noise Cancelation too aggressive on speaker calls

Has anyone noticed the background noise cancellation when using the speaker microphone is too aggressive in a VOLTE or video call? Any time I lay my phone flat and step > 3' away and talk out loud at an angle that is not directly pointed at the phone, the receiving party complains that my voice is too low or cutting in and out. It happens with multiple video apps but is less prominent in Duo. I wanted to see if anyone else has been experiencing similar issues. This has been happening on 2 different devices after my first replacement.
Using a case or skin? Don't obstruct the mic ports, they tend to be very small.
Maybe just be the design, a setting or a firmware issue (hopefully Samsung will patch if so).
Been a wet dog year for Android and Samsung...
Yeah, i have tried without a case and the problem still exists. I think the audio processor for the Mic inputs may be too aggressive or not tuned for my voice. After looking at similar problems with other devices, I think the solution lies in the location of the audio configuration files; particularly in system/vendor/etc/audio_effects.xml and audio_platform_info.xml. I'm not too familiar with editing configuration files on a non-rooted device. Is there any way to modify some of the config files to play around with the stock noise suppression?
Try disabling or covering one or more of the mics.
Eventually Samsung will probably roll out a firmware or software fix

I understand this isn't the correct place for my reply but I just bought two phones one came from Samsung which is the S21 Ultra 5G but the other is the Samsung Note 9. Both new. Every time I try to talk to someone with my note 9 they say they cannot hear me. So I have to Culp the phone and my mouth as like making a sound tunnel, if you will, from my mouth directly to the phone and they are able to hear me but not sure how well. So if you find the solution I'll keep and eye out so I can hopefully fix my problem
Historically, Samsung is known to switch to the top mic for speakerphone mode, and lower mic for handset mode sometimes ... Maybe try speaking into the top mic and see if the noise cancellation is still aggressive.
