Microphone not working after solving "MicroPError"

Hello,
My HTC Diamond on last week gets "MicroPError" and no backlight.
I dismounted the phone to clean the interior and fix the connections inside, after mountin it, the backlight was fixed and I was happy with it, because I could fix the problem on my phone, but when I make the first call, i realised that I fixed one problem and get another one.
So now, the problem on my phone is when I make or when I receive a call no one can hear me.
Can someone help me trying to fix my phone.
Best regards

Ya i can help you. The problem is the with the 2 golden hook like connectors.[ Near the camera ] You might have bend it in the process of cleaning.
To be specific , the top portion of the mobile when removed controls the speakers. You can easily spot the golden connector and make sure that it touches the upper metal connector when closing the top cover.
top cover is the one above the battery in this pic

Hello,
Thanks for your reply, but it didn't solve my problem, I checked what you said, and the connection is normal.
By the way this is not the connector for the speaker? My problem is not on the speaker, my problem is on the microphone.
My problem is not ear the others, but the other can't ear me on a phone call, so the problem is on the microphone, don't you agree?
Do you have another idea for this problem?
Best regards.

Check your microphone connections at the lower bottom . One with a black cap.

Hello again,
Can you please help me identifying the microphone.
Best regards

Hello again,
I checked it again, and the connections of the microphone sims to be fine.
I think the microphone itself is damaged, because I make another test.
I tryed to use the Voice Recorder, and found that if I talk normal on the recorder, when I play the sound, my voice is very low, almost not earable and a lot of noise, if I talk louder, when playing the sound my voice is already possible to ear, but also with a lot of noise, this is the reason for thinking that the problem is on the microphone. By the way, the black cap of the microphone falls down when I opened the phone for cleaning on the first time, is it normal.
If the problem is, as I think on the microphone, is it possible to replace the microphone, or it must be replaced the pc-board.
Best regards.

Problem with my microphone

People keep saying they cannot hear me when I talk to them. It's like I'm speaking through a can, from a distance. My warranty is not valid anymore as the phone is rooted, but I know it's been like this for a while, way before I rooted it. It's like water is stuck in the microphone somehow, or that an internal piece may have been depositioned and blocking the mic.
Is there anything I can do to solve this? Like a 3rd party app that increases the mic volume?
Thanks

Your Warranty is not voided because of Root. If you bootloader is locked you can just revert to stock.
BTW, Z1 have 2 microphones, are you sure you holding in the right position the phone? :laugh:

So if I relock my boot loader with stock ROM the warranty will still be void?
2 microphones? As in one for calls and one for the camera? The camera mic works just fine but the one for calls seems to be completely broken no matter how I hold my phone. I just had a phone call and when I answered, the person on the other end could not hear me at all. I had to switch to speaker phones so it could use the camera mic instead.
EDIT: Okay, so I just tried to set my own voice mail in order to playback my calling voice. I'm not joking, I sound just like Stephen Hawking except that you can barely hear what I'm saying. It is very robot like and distorted. Also, it seems like there is a voice recognition thing on, which means whenever I stop speak, the mic will turn off to reduce ambient noise. However, this also removes the first word I say when it activates the mic again upon voice recognition. I turned the noise cancelation setting off but no major difference.
And btw, the problem only seems to exist when I'm in a call, not when recording my voice with an app like WhatsApp or any sound recorder from Google Play. Even the built-in voice recorder works fine. Does this have something to do with my carrier?

There is not 1 for camera and 1 for calls. There is 2 microphones, 1 at the bottom of the phone and one on top behind call speaker. They both working with any application to reduce noise in phone calls or recordings. Just search on Google, is not so hard.

As I don't have this problem in any circumstance I cannot tell, play with the settings to understand if you will get better sound quality.

Maybe but I don't know, as the problem persist then I will return the phone to your carrier, let them know the problem and repaired or replaced the phone.

[Q] Can people hear you when you have calls on speakerphone?

Hey people,
I have quite a few issues with my new Z3 Compact. This is my second post here (link to first http://forum.xda-developers.com/z3-compact/help/mobile-data-disappears-reboot-t2899890?nocache=1 )..
My question is as follows: Do you guys also have the issue, that the other person in a call can't hear you when you have the call on loudspeaker? It happens to me every time I do it, and as soon as I toggle the speaker off, and use the phone normally up to the ear there is no problem.
This was never an issue with my Galaxy S3 fortunately, but now it is.
Also, any ideas for a fix?
Thank you in advance

Working fine here. Could be so that you're speaker input is broken. Normal call and speaker phone doesn't use the same input.

I am sorry, I didn't explain well enough. They can hear me, my voice is just muffled they say.
I can't wait for cyanogenmod to get to this phone I am having a bunch of software issues

I have the same issue. Usually only happens when you are too close to the mic and you have to be close because the speakerphone is not loud enough
Try speaking a little further away.

[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

Microphone doesn't work

Hey folks,
I had the problem with the stock ROM and now I have the similar problem with jackeagels 5.5.1 (SM-G800F).
My microphone works sometimes and sometimes doesn't. People I want to call can't hear me. Eventually after a few calls they do. This is a state I don't want to stay in so does one has any idea what the problem could be? A while ago I pulled some dust out of the mic hole (with a needle) but that doesn't seem to be the problem here

Mines always been dust in the hole. Get compressed air can and blast it. Very annoying.

Hey Guys!
I have a similar problem but only when I use the internal mic, the problem does not occur when I use my headset.
Sometimes, the people I'm calling say that they can hear me very quietly.
Mostly, they say that they hear a constant noise or sound like a "bom bom bom" which is in the background. I can't hear this sound myself and as I said it does not occur when the headset is plugged in.
Any help is appreciated!
Regards, Jens

What phone model? What OS?
The main mic is at the bottom, near USB port. Recording a voice note without earphone, of course, works? The mic hole is dirt or blocked somehow?

Thanks for your reply.
It is a G800F with CyanogenMod 13.
I tested the issue after my initial post with the voice recorder in detail.
So the sound is a kind of buzzing like in the early days of mobile phones when you put your phone near a radio and you get an incoming call.
When I record with the voice recorder, then I hear the buzzing. It is stronger when I say something and quiter when I record silence. Then I also made the same test with my headset, and, unfortunately the buzzing also occured. The intensity was bit lower I think but the sound was there.
Unfortunately, I never tested it with the stock rom. Could this problem be related to a software problem? I'm not sure if I backup my CM and install a stock rom for testing...
Thx!

Yeah, the best way to mak sure it's not software is backup and going back to stock. If it still doesn't work then you have a hardware issue almost certainly...
