[Q] Bad sound quality

Hi! I've just changed my phone from htc Legend to IncredibleS, and the sound quality is awful, i almost can't understand the othes side, its like that he/she is talking from a deep pipe, if i increas the volume, than its become distorted, and even worst. Also sometimes its ecchoing like hell. Did u notice any problem like this or is it a hardware failure?

noone has any call sound problem? then i shall take it to the service, except that its a very great phone.

Yup Im having the same issue. Lots of echo during calls. But only from incredible s to another person who has the same phone. I tried flashing both phones with ARHD and it seemed to have gotten a lot better, but i still hear my echo sometimes. I'm going to try to disable the secondary mic and see if that makes a difference, if not i'll have to find a way to lower the mic sensitivity.

I'm pretty sure its related to noise cancellation, try disabling that
Sent from my HTC Incredible S using XDA Premium App

Well Im going to test that tonight.. One thing I noticed is that if im talking on 3G, there's no echo, as soon as it switches to 2G (since im in a basement), i hear the echo again... But I will try to deactivate the noise cancellation mic and see what happens. I'll let you guys know of the results. I'll test on 2G and 3G

if you call *#*#4636#*#*, you'll get to some kind of info/settings menu, and can change encryption/mobile network settings, for me turned off encryption, and changed to wcdmw preferred (if i recall correnctly) made the voice a bit better, but there was still rattle in it, so its in the service now

THANX,I need it more

they have changed my speaker, and now its mutch better!

[Q] [B]péééééééééééééééép'[/B] - Very high pitched loud beep on speaker

6my\ laptop-/keyboard\ is\ broken\ \,\ please\ forgi5ve\ 6me\\ for\ all\ the\ errors
my laptop-keyboard is broken, please forgive me for all the errors
Hi all,
I still have a problem with sound-quality during a call.
When I put a call on speaker Ihear a very high-pitched loud béééééééééép.
It sounds a bit like what you get when you put a microfone next to a speaker that is transmitting sound from that speaker.
Everybody heras it, on the other side of the call it seems it even overwhelms my voice, effectively rendering a call impossible.
If I do not put a call on speaker I can speak with the person on the other side. But on the other side of the call it sounds as if my Phone is wrapped in blankets. Some described it different: "it sounds like you have put bass way up to the max and disabled all high- and mid-tones."
It sounds rather like a hardware-problem, BUT.... (and this is where I no longer understand it),
it does NOT happen with stock-ROmS...
It happened with JellyBam and Paranoid Android, does not happen with stock, ROmAUR or Experiment.
my conclusion is that it either is caused by cm10 or by JB (4.1.2).
Does anyone have any suggestions to as what Icould do at this stage_? Iam at this moment running ROmAUR but I really miss JB....
Grtz Henro.
Hi,
Whenever I put my phone on speaker while making a call, I hear this very high-pitched tone: péééééééééééééééép.
This sound is so high/loud that even colleagues in the office next to mine hear it. (And complain about it)
On the other side of the line it is heard too, people complain that they find it hard to have a conversation with me when I put the phone on speaker.
I am running Paranoid Android 2.56 Utacka (JB) now. The first day I had the phone it happened too, but I do not recall whether that was before or after PA 2.56 Utacka was installed.
It is only when I put a call on speaker. Games, music, video, recorde audio, it all runs fine. But as soon as I put a call on speker....
péééééééééééééééép'
Any suggestions?
Grtz Henrov

You are probably in a place where the mic or speakers are giving off feedback from another mic or speaker wherever you are.

The first time I was at work, alone in my office, calling my girlfriend while she was at home. ..
There was no other device around to create a loop. My laptop was still in it's bag...
I will however try again in a few moments when I walk the dog, there will be no device with a mic or speaker to disturb

Cannot reproduce it anymore. Maybe it was something in my environment...

Try to turn on noise suppression as well in dialer settings. Might help, maybe not.

How do you enable this in Jellybean?

Open up the dialer, chose settings, tick background noise suppression.

It is back. Consistently. I tried reinstalling, different roms, different volumes, different dialers, noise surpression...
Nada!
Last resort; try it on stock rom...

Collector title.
Sony Xperia T - Stock ROM - 4.1.2 Stock Leaked Launcher - Rooted soon.

So it seems cm10 related
I have been trying a lot of stuff and I m fairly sure now it happens on CM10 based ROMS.
Any one knows something about this? Suggestions?

Design faux par
I think it's down to the fact the speaker is right next to the mic on the phone. What [email protected] thought that one up. If you put your finger over the read speaker does it stop squeeling?

I'm not so sure that you could describe it as a faux pas. I often use the device on loudspeaker and actually never faced that problem, not on stock nor on CM. It seems to be either a) a different situation the device is used in (see below) or b) is device-specific which I somehow doubt.
I get the back coupling whining, but only if I'm on loudspeaker and the person I'm calling is in the same room, also on loudspeaker. Then my device picks up it's own echo on the other persons loudspeaker. But I believe this is not the case discussed in this thread as this would be the case with ANY communications device used in this setup, not only cellphones.

is there any solution for that?
with cm11 there is a whistle sound wwhen turn on loadspeaker . with the stock rom there is no whistle sound, but the caller hear it self twice .
what is going on with that phone?

[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

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

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..

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

Phone echo

Hey there, I have had my z3 compact about 3-4 weeks now and am loving it, however it was only recently that I have used it for a call or two. I have noticed a slight delay/ echo from my end (when i talk, i hear my voice a second later), any idea why/how to solve this?
p.s. I have also realised that that turning down the volume reduces the volume of the echo, figured i'd put that out there in case its related.
Many thanks!!!

I also get a muffled / echoed sound of the other party when on a call on the z3 compact and did realise that it reduces on lowering the volume. Was wondering if it was just me...

The Z3C sound get muffled because of its water proofing and the echo is probably from the other party phone being put on speaker, especial with iPhone which has the mic built near the speaker that can cause feedback.

Its mainly the muffled sound for me on higher volume, and the other party was neither on speaker nor it was an iPhone...

I think I may have solved the issue, but not 100% sure yet after only having made one call to test. But try this guys, go to 'settings' and then 'call', and deselect the 'speaker voice enhancement' option? I hear that there is a bug which causes the phone to echo when this is selected, but like i said not totally sure if it is fixed yet, but it seemed to have done the trick for me so far. Tell me how it goes!

solution for echo sound for other person on loudspeaker
I had the same problem till I solved the problem.
I've tried everything like downgrade to 4.4, changing microphone setting, repairing with sony pc companion. Nothing solved the problem so dont do that things.
Here is the solution.
Go to setting then call. Turn off microphone noise suspension and speaker enhance and slow talk.
Then restart your phone.after 5 minutes do the factory reset with delete everything option. I mean tick the option which delete your internal memory.
After that your phone is ok but dont chang any options in call setting. Don't turn off or on any setting in there like microphone noise or speaker enhance or slow talk.
Leave those options what it is.
Your phone is fine again

Question Poor video call sounds

I am facing an issue with my video calls with all firmwares of global rom since first release untill 12.5.4. the issue is the other side can't hear me well as the volume is really low, and if a group of us are on the video, only the holder of the phone is heard, and the rest are heard like speaking under water.
Tried several apps, all types of available video calls and all same, DUO, messenger, imo, line, Skype, etc.
However, if speaker is on instead of video call, the sound is amazing. Tested mics of all 3 of them and working perfect.
Anyone facing same issue and was able to resolve it? Please let me know how to get it sorted as it is really annoying.

Nothing here I'm afraid, sounds like a mic issue

Tested mic and tried with speaker, video recording and voice calls are all perfect, except video calls using third party apps only

The First thing I can say is to force stop those apps and clear cache and data and see if the issue persists,try also a reboot after done it

Done, done ,done and a factory reset also done. I believe It is something related to software priorities or algorithm to reduce ambient noise but in a bad way instead of a good way.
As example, I make a phone call with my parents on video call using duo, if my daughter is far around 2-3 Meters from the phone then they would hear her like speaking under water, if further they would not hear her, if closer would be okay. Also, even if close to the phone the volume is lower than usual. However, if it is a voice call with speaker, everything is loud and clear.
This concludes to me as a software issue or apps compatibility with this device. I cannot find a solution, and I see it a very common issue with many devices as well, not only mi 11 ultra, but for this device I cannot find a solution.
Try to make a video call using Duo with people around you, the other side will hear you only and with a lower volume than usual. If you use WhatsApp it is slightly better but still poor.

What Cover do you have? Did you try the same with the phone without cover? Because I don't have this issue (using WhatsApp)

With cover or without cover, same issue

Would much appreciate if anyone got an idea of what is going on and can explain it

a new update
-----------------------------
I found what is the cause, it is called voice gain or volume gain. it is set as low by default and cannot be changed except by root. there are a few applications that can boost gain. as gain by default is set at 1 and can go as high as you could. an app called (Microphone Amplifier) is a simple app that really helped me with it for now but still needs more testing. the app got a very low rate because of no instructions how to use it and very poor UI, but the function is simply what am I looking for.
if anyone have an idea to fix the microphone gain without root please share it with me.
I've tried SetEdit but couldnt find the correct lines (tried volume_voice_xxx) but non of them worked.
