[Q] HTC One Microphone Issue

So I recently rooted my phone and installed CWM and currently am using a Nandroid backup of the Tmobile Stock ROM. Here's my issue: The microphone doesn't work when making phone calls. I'm trying to figure out if it's an issue with the phone itself or if I did something when I rooted/flashed a rom. The speakerphone microphone works but in regular calls, nothing gets picked up by the microphone. Any ideas?

I think we have the same issue. Here's my thread regarding my problem:

People on the other line say my voice is very muffled and distant. And I also don't hear anything on the right side when recording a video. It must be a defect with the bottom microphone. I wish there was a fix rather than having to get the phone replaced.

Thanks for the reply. Is your new HTC One working correctly now? Clearer sound on calls and records both left and right channels of audio?
Also, you said you went to the dealer to get it replaced. I ordered my phone from T-Mobile.com and they said I would have to mail it in first and then they'd mail me a replacement. I wish there was an easier way.

I went today, and for the moment it seems to work okay, I brought my phone directly from the dealer, and they replaced me with another new phone.

It's definitely an issue with my bottom microphone because when I make a call using the speakerphone, the other caller can hear me perfectly, since the speakerphone mode uses the back mic. But regular calls using the bottom mic sound awful.

Has anyone been able to get a replacement that has resolved the microphone issue? I just bought my HTC One from T-mobile a little over a week ago and I'm debating whether or not I should return it to the store to get replacement(which may have not solve the issue) or to send it to HTC through product warranty and hope for them to repair it.

I've got the exact same issue here in Australia, just the last few days when I make a call the person at the other end can hardly hear me but when I put it on speakerphone its fine. Looks like I'll have to return it. I bet I don't get a replacement. Over here the phone has to be sent back to be fixed. I had terrible issues with my Galaxy S3 that was finally replaced after being sent back twice. Thought my luck would change with the One but looks like that isnt the case. Very frustrating.

Can anyone shed any light on this issue yet? Mine messed up out of nowhere... Went to a concert a week ago and recorded a video and it sounded fantastic, a week later however, when I record a video all I get is very loud static. Same goes with voice calls. If I set it to speakerphone they can hear me fine. Idk whether to contact HTC or AT&T I have the insurance + warranty.
Any help would be appreciated. I don't really wanna flash or root it yet because of warranty issues and what not.

I had the same issue with the loud static through the bottom mic but mine was from dropping it no more than 3 feet from the ground with the otter box on. I had my carrier send it out for repairs and the replaced the flex board and the bottom speaker and mic and since I've gotten it back, I have no more issues with static on my phone calls.
However, I am getting a lot of complaints of people not hearing me when I speak or it sounds like I'm too distant. Now I'm frustrated.

Hmm did it cost you any money (if you don't mind me asking)?
HTC wants me to ship it out and I haven't contacted AT&T about it yet.
Idk what the better choice would be!
I'm glad your static issue is gone though! It's very frustrating to not be able to make phone calls on my cell phone...

It didn't cost me anything as it was under warranty. I got the phone the day it was released.
I'm not sure how it is in America, but I'm with Rogers and they deal with all repairs. So, they sent my phone out to HTC and had it returned to me at no cost.

To be honest I don't even know how it works here either. I've never had to send a phone back.
It's seems as if I can go through HTC directly or through AT&T.
Looks like im going to have to do some research!

Same problem, just crept up out of nowhere. Speakerphone works during calls, but callers tell me I am going in and out, so I was like, what. I tried to record a video right next to my tv, no audio. Hmmm, opened voice recorder and I was yelling into phone and it came out almost silent. Voice search is also useless unless I scream at my phone, that's what really started this whole thing wondering what is going on as I really do use Now for alot. Owned phone from day one, 64 GB ATT model. What gives.

I dropped my phone from literally four inches above a hardwood floor - EDIT - possibly relevant detail - I dropped it while in the act of recording video - and had serious static issues immediately after that.
Before sending it in for repair, I tried gently rapping it a few times in various ways ( see http://en.m.wikipedia.org/wiki/Percussive_maintenance ).
I also experimented with recording a few really loud sounds thinking some kind of automatic gain control on the dual membrane mic may have gotten stuck at an extreme value.
One way or another the problem went away and never came back. I consider myself lucky.
Sent from my HTC One using xda app-developers app

I just called HTC and they have basically told me I am out of luck and aren't going to do a thing for me. I purchased an unlocked AT&T HTC ONE brand new for 800 ish dollars. Since I am in Canada, that's their loop hole I guess. Either way, I don't care what country I'm in, I paid 800 for a product that clearly has a hardware issue.
SHAME ON YOU HTC, ILL NEVER SUPPORT YOUR PRODUCTS AGAIN!

This is how I fixed mine.
Start the recording app, you'll see that the visualizer indicates that it is recording sound, it's the static.
now grab 2 bristles from a toothbrush and gently stick them in the bottom mic
rotate them gently, you'll notice the visualizer getting smaller if you're doing it right, means less static coming in.
do this until the static is gone. worked for me, took 5 minutes.

Same Issue
I am having the same problem now. My phone is one month old and it was working fine and then i rooted the phone two weeks back it still was working fine and then today suddenly i didn't hear anything when my friend called me thought it to be signal issue then it happened same with every one of my calls. Do i have to unroot and lock my boot loader before i take it to HTC or at&t?

Possible Fix
Hey all,
Here's what I did to fix my Sprint HTC One
I went into system --> build.prop
I changed persist.audio.handset.mic=digital to persist.audio.handset.mic=analog
Reboot
This solved my issue after I've tried many things. Here were some temporary fixes that worked for me before I found this permanent fix:
Screaming into the microphone for around a minute. After that, the rest of the call seemed to work. Note: The microphone is on the bottom, underneath the bottom speaker.
Covering the second microphone that's on the BACK of the HTC One (you'll see it in the top right). That helped as well.
I hope this helps someone.
Cheers.

I too had a problem after about six months... No one could hear me when I spoke into my phone. So I took a needle and carefully put it in the small hole in the bottom, scraping against one of the sides - and voila: up came some pocketwhool (is that the word for that hairy dust that comes out of nothing in the pocket all the time...?)
The microphone has worked perfectly ever since... ??? ?

But there is a way durring the call if I turn speaker on the other mic(located on top of the phone) is working and the person on other side can hear me.

N910T no sound at all, please help, WILL DONATE $20 IF SUCESSFULL

N910T 5.1.1 DOK2
Not sure how it happen, Just buy from a guy in Craigslist and find out it have no sound.
No sound at all ( that mean when turn on no sound, using the phone no sound, call no sound - the call app freeze or foreclose when call), YouTube foreclose when I hit play, sound recorder foreclose when I hit record ( look like any apps touch to the sound thing will foreclose when run)
I had tried other kernel but no luck.
At first I think it was water damage but when I look at water indicator it still white.
I ask the guy and he said the phone got like this because last update. Hard to believe ppl on CL but I have seen some phone lost sound because update too.
Serial number was null before, I have try to flash a new EFS and I get SN back.
Thanks a lots, I will donate $20 if anyone can help me solve this problem.

Install a custom ROM on it & test... Might be software related

Same thing happens. No luck with CM12
Voice recorder fails " internal application error. Microphone may be in use"
Look like all apps cant access the sound part? codec?

Water damaged phone?

At first I think it was water damage but when I look at water indicator it still white.
Second, if It got water damage why all the apps utilize sound fail? Maybe only one speaker or microphone fail when they get wet?

One way is trying another Motherboard or its the speaker and Microphone damage, you can try changing the Speaker and Mic to see it that works or get another MB.

Did you do a full odin to stock? Like completely wipe everything

Did you test the phone before you bought it?

Have you tried using a Bluetooth or wired headphone? If the previous owner used a cheap wired headphone and the tip of the headphone broke inside of the jack. Software on the phone is going to redirect all audio and mic to the headset jack. With no headset present it would render the internal microphone and internal speakers useless

The phone turn out is hardware issue. There is a small corrosion on the board.
Anyone in here offer anything for it before I sell it on ebay?

Faulty microphone?

Has anybody had any issues with the bottom microphone on their S10 plus not working?
If I'm on a call the person on the other end can hardly hear me. If I hold the phone upside down and speak into the top mic or put the call on loudspeaker they can hear me fine.
I sent the phone to a Samsung authorized repair centre and they said the microphone was faulty but they wouldn't cover the repair because knox was tripped and they wanted me to pay for a new motherboard.
Has anyone had any similar issues or any success with changing the microphone?
TIA.

Question Zenfone 8 problems with speakerphone during phone calls

Hi,
Has anyone have such problem with speakerphone during phone (or whatsapp/viber etc) call that
All MIC's passes tests OK, record and then play my voice very well and loud.
But when I call someone or someone call to me and I active speakerphone to put phone away from my ear - there are mess like echoes, some robotic voice like signal excitation and interference started each time for person on the other end of the line. Person hears himself more often than my voice. So it's impossible to talk normally on speakerphone. I hear companion very good, but for him it's mess. But if I deactivate speaker and use earphone (in front of my ear) - then everything is ok for me and person on the line.
Does anyone know what could be wrong? Problem persists on each FW which means that problem is hardware. I checked all mics in ,12345+= test utility. Every single microphone is ok. But it seems that when they work together - sometihng is going wrong. There are 3 mic's in this phone. First one is located on board 90AI0060-R10010 (bottom left corner), and this part can be replaced, it doesn't cost an arm and a leg. Second one is located in top upper part on main board and it looks like it can only be repaced by replacing motherboard which is cost a lot of $$$ which is not acceptable for devices not covered by warranty anymore (unlocked BL). Third mic installed on board 90AI0060-R10020 under back cover (where rear camera is located) and also can be replaced, price about 10USD.
But where is controller/unit which operate by these mic's?
Is there anyone who has or had such problem? What part(-s) were replaced is service under warranty?

Hi
I hat similar problems. I tried a lot of adjustments at the apps and the phone. Set the phone to factory settings. Nothing helped. Even the upgrade to Android 12 didn't change anything. Finally I sent it for warranty repair to Asus workshop and now I am waiting to get it back. Hopefully tomorrow I can tell you the result.

Ok, please also let me know (if possible) what part(-s) will be replaced.
There are 3 microphones in our phone. And I guess two of them are operate during phone calls on speaker. Main mic on sub-board which is located at the bottom of phone and second one - noise-canselling MIC which is located on motherboard (top part of phone).

Hi, today I've got it back. The workshop protocol says they made a firmware reset (same I already did before and told them). And the result is, the fault is still the same. This was second time I sent it for repair. First time the WLAN module broke down. They changed the motherboard and after getting it back from the asus workshop the the speakerphone function didn't work any more. You can see, there are absolutely specialist at work.
