Trouble with both microphones. "Sound muffled or quiet in calls?"

My new HTC One seems to work very well indeed, but I have an issue with signal during calls.
In 3G mode (or auto/WCDMA/GSM/LTE) my voice drops out in the middle of conversations. The person in the other end describes it as me just "dissappearing" for a few seconds, then returning. The call is never dropped entirely. If I turn on "only 2G" the calls are working just fine...
I hope it is an issue with my SIM-card. Can a faulty sim cause this? I had to use a nano-to-micro adapter in my phone, and I just dont't trust that plastic thing. I've ordered a new sim that has support for LTE also, but I don't know...
Any thoughts?
Updated the title to clarify. See second post.

Looks like our friends in the Sprint department has this thing going on. I believe this is my problem and not the one I described in the first post here. Like the first post reads, a fix is maybe in the works for the Sprint, but don't know about our version, though.
Just wanted to post this here if others are having the same issues.
PS: Like mentioned in the Sprint thread: I am righ handed, but I always hold my phone in the left hand during calls, so this problem might actually be caused by my pinky covering the mic - and therefore blocking my voice getting through. Stupid, but it might be it...

[Q] Phone calls sound muffled to others

I am having a problem that others also seem to have on this phone, where people on the other end say it sounds like I am in a wind tunnel or several feet from the phone. My fiance has the same phone and I swapped phones with her and spoke over it and sure enough that's what it sounds like. There's a thread about it over on the sprint forums http://forum.xda-developers.com/showthread.php?t=2262648
I am on sprint but decided to take this over here because I believe there are more users on the international side of things. Basically what I would like to know is, is anyone here having this problem. On the sprint forum about this issue they said it is a software problem, however I don't believe a software problem would be consistent through rom and kernel flashes including wipes. I rather not change out my phone even tho it has a few dings and scratches because of the risk of getting one with the updated hboot and not being able to downgrade and s-off again. However I also seem to be having an issue with bluetooth, where I have to carry the phone in my hand in order to have reception, even if I so much as tuck the phone under my arm I loose all bluetooth reception to the point the headset disconnects, so I think I have a problem with the bluetooth antennae.
Does anyone else have any of these problems?

Hi, I have exactly the same problem. I have bought an HTC One without operator in France.
Sometimes, the person I'm talking with thinks I'm in a cave or tunnel, and after 30 sec (approx.), he can hear me properly. Or sometimes, he cannot hear me at all or very very low and jerky sound. This disappears if I shout few seconds over the mic, then communication is good...
I was waiting the 4.2.2 update with impatience, hoping this will solve my problem (if there was a bug correction for that), but still have the problem after updating (jerky sound which disappears if I shout, for the moment I don't have the tunnel sound problem).
Now I suppose there is a problem with the mic (which is a twin-membrane microphone to deliver distortion free), and I think I will send it back to maintenance to fix it, unless someone knows how to solve it...
Thanks for other feedback.

I am running 4.2.2 and other people have told me the same thing about me sounding muffled.

Speaker cutting in and out after update

Updated my phone to the latest update. I was looking forward to volte and simultaneous voice and data. Now my external speaker doesn't work right. When I'm on a phone call speakerphone doesn't work and the alarm sound cuts in and out. The odd thing is when I play songs off of Spotify the external speaker is fine. Has anyone else seen this issue since they took the new ota?

I've noticed that when I'm on a voice call the speaker has a lot of static noise when the volume is all the way up. When I turn the volume down or put it on speaker however, it sounds perfectly normal.

Yeah I have that same behavior as well. I still can't get the alarm to have sound. My phone just vibrates. No one else is having sounds issues after the OTA?

I had to turn off HD voice.
My volume is fine, but my volume up button rarely works. I have to go into settings to turn my sound up. Down is fine.

for all of you having issues try doing a FDR.

My alarm works fine but I'm using Zedge for my ring tones and notifications. Don't know if that has anything to do with it. What I little I have had HD voice switched on I get the same static noise in my speaker at full volume, no static with HD voice off. I agree with the_rooter about HD voice.
Posted by the the_rooter in the tread I started.
"to me it feels like advance calling is still in alpha stage. I have it off right now till i see it gets better"

Called Verizon on this issue. They had me turn off advanced calling and wipe the phones cache. I left the phone be for awhile as the sound stops working a few hours after reboot. Got the sound issue again so I rebooted the phone into safe mode. Still ran into the issue after a few hours. Finally I did an FDR and still had the same issue. Verizon is sending a new phone next week. I will keep everyone posted if this was a manufacturer defect.

So voice sounds great over car Bluetooth after update but earpiece on phone sounds like crap. Anyone else have this issue? Does the FDR fix the issue?

Just wondered if you received replacement phone. I just activated advanced calling last night and now my calls have static background noise.

I just went in to settings, turned advanced calling off, tried a call and sound was back to crystal clear. Then i turned advanced calling back on, tried a call and it had static hiss again. Obviously a glitch in the advanced call update.

Glitch in advanced calling, period. I doubt its phone specific.

I worked with Verizon tech support and after 2 hours of trying different things they sent me to a store to get a replacement phone and new sim card. This "UPDATE!" DID NOT FIX the problem of poor sound with Advanced Calling turned on for HD sound. Their explanation was that the update does not load properly and the only way to fix is new phone plus the new sim card, but this did not correct the problem.

I can't understand how a new phone would help anything. What's the difference between that phone and my phone? Is it a different build? Maybe a new SIM card and a full wipe?

This is the first update that was released for advance calling and honestly it's still in the alpha stage. The service is buggy. It's not the phone. Why go talk to verizon when you can go directly to the source. Motorola....they are the ones that know the answer and they would give the same one you get here.

This update wasn't aimed at address poor sound with advanced calling, so no big shock there.
The sound quality can probably be fixed from the network end. You dealt with a tier 1 tech who didn't know anything. These same complaints are made on other VoLTE enabled devices unless using HD calling, which is rather rare.

The tech last night was a tier 2 and has spoken with others with the same problem. The unique issue with turbos is that wr cannot use data while on a call without the advanced calling on, so it is either bad call/data during call or clear call/no data while on a call. The technician i spokebwith today was also a tier 2 and was calling Motorola to inquire as his internal note system (forgot what he called it, those are my words) identifies a number of users with this issue and he had just completed 3 calls prior to my call.

Go look at any Verizon VoLTE device and they all have the same complaint: poor quality unless an HD call.
It is not Turbo specific, no matter how much you want to believe that. I've done the tech support thing; they usually rely on guesswork and scripts unless you get in contact with someone not on the frontline--which you did not.
The turbo is a very popular device with Verizon right now, I am not shocked that others have called about this. What you are seeing is a result of popularity, because other VoLTE devices on Verizon also have this issue, indicating a more likely network issue. Either its a network issue or everyone with a VoLTE phone on Verizon keeps making the same mistake in their firmware. In that HD calling sounds great, I don't think its the devices at all.

Update. Holding my phone in landscape mode and pressing the speaker location with my thumb would cause the speaker to turn on and off. Good to know its the hardware. The new phone has since fixed the issue.

When I was on the phone with Verizon they mention this as a know issue and that it would be fixed with an upcoming update. The advice I got was to just turn off HD Voice and wait for the update.
Support had me clear cache after turning off HD Voice.

I know other phones aside frone the Turbo have the sound problem if they have downloaded Advanced Calling and have HD sound turned on. The additiinal problem for Turbo users is that without the AC turned on we cannot use data while on a call. The technician did not know this to be an issue until i read him the error message that appears when attempting to use data while on the phone with AC off. I leave it off, but frustrating when i need to look up something for someone calling me or when using maps and a call knocks it offline. Oh well, hope for an update sooner rather than later.

Question S21 Ultra sometimes doesn't show that someone is calling me

Hello,
For many months I have had a strange problem with my S21 Ultra, namely it does not seem to show me at random times that someone is calling me, no matter if via the cellular network or some communicators, it simply does not show notifications that someone is calling no matter how is calling. I often have it that only when I pick up the phone, unlock it and check something on it, suddenly messages come that someone tried to communicate with me, and only from then on I can answer calls until I hang up the phone and in an hour or two the same problem - over and over again. I have such an impression as if the phone itself went into some hibernation after putting away, although I have no indications that something like this is happening, because everything looks normal. The phone has the latest update, and I have restarted it several times with no effect.
I would like to add that this happens both in an apartment where I have wifi turned on (I do not use lte calls), and when I am outside while walking in the city.
Is there something I can do to fix this?

This is a very strange issue indeed. Have you checked if your phone has cell coverage when the screen is off? Did you try calling yourself from another phone and number? If the answer is negative to either question, I would suggest resetting your network settings. If that fails, try a factory reset which should solve any issues. If the issue still persists, it could be hardware related and you might need to take the phone to Samsung centre to get it checked.

I don't have a second phone to call myself. Friends say that on their end it sounds like I am not answering the call (i.e. they have a call signal, but just nobody is answering). They have no busy or unavailable signal. What exactly do you mean by a network reset, what would I exactly have to do? I was thinking about a factory reset, but I'm afraid that I will lose all my data and application settings. I do not know if it matters, but I have been using this phone since the premiere of the S21 Ultra, and when I bought it, I transferred all data via the data migration service from the previous S10+ phone, to which a few years ago I similarly transferred data from the S9+, to which I transferred data from S8 + earlier

Maybe you have the "do not disturb" option on? When I have this on, I can't see who is calling me.

I checked, unfortunately it's not that, if it were, I would never see someone calling, but my problem seems to be random.

u need to go to settings>general>reset and there tap reset network settings..

Hi,
I experience very similar problem. I tried to reset network settings, "hard" reset the phone, playing around different mobile network settings... nothing helps. I'm not sure if it is phone hibernation issue or kind of removal of the phone from cellular antenna.
I have another phone I use to watch this s21ultra issue. Practically each day it happens that the s21 ultra does not react to my call, of course most of the time it works properly, but there are some tries, when it fails. In such case on the phone I call from I get a message "user is not available". But then, leaving the s21ultra untouched for 10 minutes I get SMS saying that someone tried to contact me, so it is not obvious that the phone hibernated.
I was not able to reproduce the problem on the other sim card put in s21ultra (the carrier is different). I was not able to reproduce the problem on the other phone and the sim card from taken from s21ultra. In my opinion it is related to "weak" mobile signal and kind of "sensitivity" of s21ultra to low signal quality.
I reported the problem to my mobile network provider, but I'm still waiting for the answer. Anyway, I'm going to do the following:
- ask for sim card replacement (cheapest option),
- (if above does not help) go to samsung service and ask to check the phone - I hope they have some diagnostics tools,
- (if above does not help) install the second sim card (from different provider) and configure redirection of calls in case of "user unavailable" - I know it is "stupid" solution - but at least one of the carrier should work
- optionally root the phone - Can anyone confirm if it may help? At least I could enable toggling airplane mode each minute

Question Call Quality?

Has any one noticed any issues with call quality? I am getting a noise reduction hiss. Every time the remote caller speaks I hear a background hiss around their voice. Once they stop speaking the background his goes away.
Did not get this on my pixel 6.
Is anyone else experiencing this?
Thanks,
RJR

Not here, tried a lot of calls (i use a lot the phone for work) and nothing, audio quality in-call is perfect. Sometimes those problems are on the other side and not ours. Do you have this with every call?

What is happening is when someone on the other end is talking you hear them talking with a slight background hiss. Once they stop talking everything goes silent.
I am accustomed to always hearing a very slight hiss when the call is connected whether the other party is talking or not.
Not sure if this is the new norm with cell phone moving forward.
RJR

call quality has been superb for me via US Mobile.

No issues here with Cricket Wireless as my carrier.

Call quality has been great on both Tello and SafeLink.

Its more data efficient to take the "silent" times and actually just transmit silence (a long line of "0"'s).

I've had several calls, and all were crystal clear. So much so I think I'm on a land line. Not sure what network you use, but that may have something to do with it. Also what signal you're using at the time (5G, LTE, Wi-Fi calling, etc).

I have been reading up on this and it seems that what I am hearing is called comfort noise when the other party is speaking. It is most prevalent when the volume is set all the way down.
I am trying to find out if my pixel is defected or if everyone is hearing the same same thing since this was not the case with my Pixel 6.

did you get any progress with diagnosing?
i have the same issue. a hissing noise on-top of the caller voice, that reduces to crackles when the other side is not speaking. its with multiple callers on the same network. it happens with or without wifi calling. on regular calls using the phone app and on calls using telegram or whatsapp. i tried on 4g and 3g. it starts hissing in while making the calling sound, that means its something in the hardware. the device is rooted, and "converted" to GVU6C (global) model from G03Z5 (japan) using an alteration of the init file and also installed VOLTE module and enabled 5G using an app called network signal guru.

Unfortunately, I ended having the call speaker (top) replaced. Did not cost anything since it was under warranty. Depending on your service center it is usually a one-day repair.

i found this on google support. it seems like a common issue. thats a shame. I'll have to try my luck with the importer in my country because there is no official support for google devices. fml.

I faced a different kind of issue. Every 2/10 calls i hear some sort of clicking noise In my phone earpiece. It disappears after a few seconds but it happens sometimes. I got scared when it started happening the first few times. I think this issue appeared after the November update. Anyone else faced this?

I'm not seeing this as a common issue but merely a few users. Support told them to either return the device or get it fixed. Returning after the 15 day period is unfortunate because you'll get sent a refurb. However, if it's noticed before 15 days after receipt then you can return it, get your money back and then buy another new device. I believe the return period for hardware related issues should be at least 30 days but that doesn't seem like it's in the cards. In your case without support I'm not sure there is anything you can do other than get it fixed which is a bummer. My call quality has been stellar as others here have said so I hope you and the OP can get this resolved.
