Speaker not fully duplex?

Hi,
I have a very weird problem with my Tytn II, which I bought little over a week now.
People I was talking to complained they didn't hear me very good, the sound appeared to drop. It occured to me that it was happening when I used the speaker (handsfree) of the phone.
I did some testing, and this is what happens:
I (with the Tytn II) call person X, and when I and person X are talking together, person X cannot hear me, the sound on his side simply fades to nothing, until 1 of us keeps quiet. The same happens when for example sound from my car is picked up by the phone, thus resulting in the device not being usable in the car, since there's always some noise. I however on my side keep hearing person X, it's person X that doesn't hear me.
It happens with 2 sim cards, everyone I call, did a hard reset, HTC support doesn't know the problem...
I'm puzzled. Can anyone suggest anything? Or is it faulty?
Thanks

no, mine does the same thing. I got it a few days ago and when i used speaker while driving, i could hear the other person perfect, but they cant seem to hear me. It feels like half duplex. i hope this is fixable

Damn, it seems widespread then...?
Anyone who can test it?

maybe it has to do with whatever noise cancelling algorithm is in effect is mucking everything up

Meaning that every single device would have this, and thus mine not being faulty?

I had the same problem but remembered that there was an automatic sound function which turns down the volume when talking is too hard and turns it up when to soft. Its called microphone agc and you can find it under system configuration. Now that it's turned off my dutch htc tytn II works fine in handsfree mode. Hoop this helps you also

It's already turned off :-( .
However, I just called with HTC, and they said it's because of the mic and the speaker being too close to each other, and thus it compensates.
They say every model has it however, they did a test today and the result was that it was a feature, not a bug...
Anyone here who does not have it on his device?

I have this problem all the time, both on speaker and just using the phone to my ear as normal.
People complain I am very quiet or that the sound is choppy and I sound like a robot
I used to have this problem on the O2 XDA IIs a few years ago.

Anyone else have it too? I'd like to know asap if this device is faulty, or if it's normal?
Sometimes, it seems that when I'm holding it to my ear, the sound seem to drop on the other side too...

I have exactly the same problem. People have trouble hearing me with loudspeaker switched on. Without speaker they can hear me perfectly.

I have the same problem too. Just try to disable the Microphone AGC thing and it fixes the problem. Thanks downnootje.

I have teh same problem , but I tried something and it is improved the Operation , try to minimize the Speaker volume to the minimum level and then it improes a little and it works for me ; not all the time but that is what we can do at the moment

I'm convinced now that it's a mojor problem.
Mine even got worse: since yesterday, it's happening without handsfree too, people can't almost hear me when I just hold it to my ear...
Is this a phone still, or can't it be used as such?

try enableing Microphone AGC thing, restart phone, and disable it

Me too. Juz got my set 2 days back. The other party hears my voice intermittently chop-off...
I have faced the similar problem on a particular China-made TV phone too. Tested two other units of the same model still the same. It seems to me the phone design issue, as after I changed to another model of China-made TV phone, the problem solved.
Sigh! Already got this expensive phone, think have to bear with this feature then if it is really cannot be resolved by new ROM.

same problem
i have the same problem...with my 8525 when I was on the train or in a similar noisy situation i never had any trouble with people hearing me on the other end...with the tilt i can't even carry on a conversation on the train...i called tech support and they told me to swap it out for a new one.

I've tried that and it doesn't help! Quite sad about it. I need to use speaker handsfree especially during driving.... Don't really like to hook-up the headset or BT headset... too messy for wired headset and too tedius (charging) for BT headset...

Now that I know its half duplex it works pretty well in the car - I just wait for the other person to stop talking
Surur

I will be sending mine to HTC for a planned hardware fix as they agreed there is a defect that affects all kaiser and tilts, but NOT the MDA VARIO III. this is a known issue and is hardware related. Good news for those who havent purchased one yet. I will sell mine on ebay if they dont asign me a RA soon. I rather have the MDA VARIO III as it has 2 cams.

(doesnt your HTC TYTN2 has 2 camera's?)
Same problem here. Hope for a sollution soon!
Will call HTC too soon, so theyll have more complaints about this defect.

Faulty speaker... perhaps?

Hi,
First post, so apologies if I'm posting in the wrong place, but I wanted to find out if anyone else is having trouble with the speaker and microphone on an S730?
I eventually received my handset from O2 UK (XDA Atmos) and managed to make 2 voice calls before the speaker stopped working. I can place calls but I can't hear a thing (completely silent), and I no longer have any key tones.
On investigation, it works fine using the supplied headset, and if I grip the phone in a particular way so to gently squeeze the top section, the speaker works again.
I've googled until I'm sick and can't find any references to this on a 730, but quite a few on the 710. Anyone else had this problem.
Oh, and just to really annoy me, O2 are out of stock, so their next day replacement is going to take 18 days!

If pressing on the case kicks it back in it sounds like something is not connecting properly anymore, its possible you could fix it but I would go for the replacement. Does the external speaker still work? I have not seen any other threads about this issue but I am sure we will.

It's hard to tell but I believe the external speaker works as it does ring. However, I'm not able to switch it to speaker phone mode. Doing so does nothing. I also seem to have more luck placing calls than receiving them.
I guess I'll just have to wait for the replacement. Bit annoying that my 'loan phone' from O2 is a nokia 6300 though - hardly comparable! Just hoping the replacement doesn't suffer the same problems...

You sir are the first one to report this issue that I have seen, doesnt mean its not but I wouldnt bet on it being too widespread of an issue. Sounds more like something went wrong in shipping / production and you got unluckey Hope your replacement shows up soon!

Well, my replacement finally turned up today..... and it works just fine. Let's hope it was indeed a one off, or damage in transit, or cosmic rays or something.

[Q] No sound from earpiece or from music, but notification/alarm/other sounds work

Hi Forum,
I orginally posted this topic on the man Q and A board but it was buried quickly with no response. Perhaps this is a better venue to ask.
My phone is roughly a year old, and today I ran into a weird and potentially phone killing problem
I received a few phone calls from my girlfriend today, the ringer rang loud and clear, but I heard no sound from my ear piece. After a few "Hello?"s, I hung up thinking it was a bad connection. Upon seeing my girlfriend afterwards, she said she heard me on my end. So I got her to call me again and I tried to use speaker phone, and I could hear her fine.
Doing some research on google, I only ran across one other person who had this problem, and upon seeing this, I tested my music player, (as theirs didn't work), and mine doesn't work either
This other person said the problem resolved itself a day later.
In short, my ear piece has no sound during a phone call and my media sound doesn't work (though it works w/ headphones.) My notification sounds and speaker phone DO work, as well as my alarms
Do the notification and speaker phone speakers come from a different place than media and ear piece speakers?
Do I have a software issue? I tried the "push the speaker down" solution but to no avail
Should I wait like the other person?
Any suggestions?
Thanks forum!

I had nearly the same issue, except mine got to the point where the speaker phone didn't work either. Music played fine, phone calls stopped working. I went through a lengthy process of accidently deleting everything I had on my phone, which lead me to buy a USB Jig, install the stock ROM and it worked perfectly. I would suggest trying this before you try and physical fixes on your phone.

Thanks for the suggestion SGT_Watkins
I am an absolute noob when it comes to this stuff. So it took me a while to even figure out what you were saying
BUT, after a whole night of reading and flashing it WAS FIXED!!!
I am quite tempted to phone Samsung and give them a piece of my mind after they told me some hardware was defective even though they clearly weren't listening to what the problem was
Thank you again!

How did you solve this?
I have the EXACT same problem on my Galaxy Nexus. I've wiped it, tried different ROMs, kernels... Nothing solves it! It's like there's a persistent software problem that survives flashing and even battery pulls.

My phone had this same issue not long ago. It was after I had used some headphones for about an hour. I work in a paper converting factory, so I assume some dust was packed in the headphone jack and made the phone think something was plugged into it. I turned my phone upside down and used a paper clip to scrape it all out (compressed air may have been safer). After a few tries, all sounds were working properly again.

Speakerphone Not Working Echo

Hey guys,
Bit of a strange problem, recently my speakerphone has stopped working. Whenever I place a call on speakerphone the other party can hear their own voice echo and this becomes progressively worse over a couple of seconds till neither parties can hear each-other and its just a loud fuzz.....everything else on the phone is working perfectly! It's never been dropped or anything...its still in immaculate condition! I am running the latest firmware (UK) and it's started happening randomly....any ideas on how to fix?:crying:

I got the exact same problem and no solution so far. I've tried various rom versions (4.4.x - 5.0.2 and CyanogenMod Nightly), but it didn't help, so I'm afraid it's a hardware thing.
I don't know if you also experienced that, but if I let noise cancellation (in setting) enabled my calling partner also does hear an echo and my voice is much quieter, without using the speakerphone.
In my case it's possible that I damaged the phone my self, since I had to replace my whole case and the lcd, after falling damage.
I would appreciate it if someone could tell me which part exactly is causing this problem.

I had to change thel unit also due to the touchscreen bering cracked.
Speakerphone, or 'audio output', is not working. Although I might have had this problem before. I can't remember.
I read on another forum that the bottom speaker only comes on when on speakerphone.
So I'm thinking maybe damaged it while repairing the replacement lcd unit.
I hope this is not the case. I have yet to do a factory reset. Just need a bit a spear time to do it.

I have this problem too.
I broke my screen and i replaced it with a new screen(including LCD) by myself, and after that the speakerphone stopped working. It's so strange because microphones and Speakers work ( i have tested it in *#*#7378423#*#*).
Mah!

My replacement lcd came within a new case without the back panel. All I had to do was place the motherboard in the new case.
The new case had a bottom loud speaker already in it. I have, last week, opened the phone up again and replaced it with the original speaker. Unfortunately, still cant get the speakerphone to work.
I will try an reset one day , once i make a note of my apps and back updata.
Has anyone tried a reset yet?

[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
