non-working mic on MTCD PX3 2gb with android 7.1.2 - got full refund on aliexpress - MTCD Android Head Units Q&A

aliexpress case management decided: full refund without return...
I had opened a dispute because of the mic problem. and also the unit was advertised as having a dvd player and of course does not come with one.
So now I need to fix my free head unit.
If I YELL into the mic, I can be heard with some static. However, Google voice commands will not work because of the horrible sounding voice input.
I installed an external mic, and no help.
In between insisting it was ok to close the dispute (which I guess was a scam attempt), the seller suggested that there was an external mic module that might help? or that the bluetooth chip may not be functioning correctly.
does the soldering external mic onto internal mic "fix" address this specific problem? if so, will google voice command then work?
I've been searching for answers for several days now and I'm not clear on it. I hope someone out there who has done this can shed some light?
Also... guys if the unit does not work, that dispute button apparently isn't just for looks.

i did not, but it looks exactly like that except for not having the iR sensor and the buttons being labeled differently.

From what I've read, they're all built and designed so horribly that most have microphone issues of some sort. They're all the same. Someone correct me if I'm wrong. All I'm saying is that if you order one and it isn't working right, use the dispute button. Maybe some day they'll actually make decent units and advertise them correctly

Is it. a microphone. issue or just. something in. the software ? it. seams everyone has this. problem mincluding me.. microphonen will. not. work anywere else besides bluetooth app (dialer app)

I took my external mic while in a BT call cupped it in my hands and put my hands to my mouth and talked into it so the headunit mic couldnt pick up my voice, the person couldnt hear me at all. Tried louder & louder & they couldnt hear me, I literally need to almost yell with my face 5 inches from the screen for them to hear me.

This seems to be a common issue. Even I have this issue. Fortunately the mic works beautifully during Bluetooth calls. Please let us know of you find a fix for this.
Cheers,
Rahul U S

Anyone lucky enough to find a fix for this?

Help - First major mic problem in HTC TC

Hi everyone, how are you?
For about a week or so i have been having some problems in my touch cruise.
My mic stop working (more or less). I have been trying to solve it by myself and with some help of forums in my mother language, but even so, i failed.
The problem is this:
When i answer a call, the person in the other side is not able to hear me at all. Only if i shout real loud and if i take the device from my ear and put it right in front of my mouth, they can only hear whisper like sounds.
If i am the one doing the call, it happens the same thing.
If i try to record a voice note or something like it, almost the same thing. i cant hear myself talking. Only in the situation i mentioned above, with the phone in front of my mouth and with me shouting, its possible to ear something.
I have done a hard reset just now and it remains with the same problem
do you know what might be happening? do you recommend some proceeder before i try sending it to be fix?
I bought it online, in expansys (and i'm in Portugal) and they said that i have to contact a company that makes the "fixing" for them (outsourcing services you know). I tried to call them but i didn't got any answer yet.
I know who is the dealer of the HTC brand in my country (Novabase).
Should i contact them directly, should i go first to the other fixing company or should i try some mambojambo in registry or some app that may fix the problem?
Please help me. My phone/pda is (almost) my life. I need it for work (and the amount of money i gave for it does not include problems of any kind )
Thank you in advance and sorry for the HUGE post.
I will be waiting for your guru answers =)
stay cool
up...
please
Unfortunately, it really sounds like a hardware problem, especially you already tried the hard reset. You can confirm this by using the headset. If everything works fine using the headset, then your phone's mic is broken. And if that's the case, sending it in for warranty repair is the only solution.
yeah, you are right. with the wired headset it works (oh, just to think about it, does your headset moves arround insite the jack? it seems loose)
it has to be hardware then. :S
SH*T =( so much money for this :S
thnaks anyway =X
Major mic problem
I've bought 2 HTC TC Cruise and both of them have the same mic problem, so it's supposed to be a quite common issue: suddenly the mic becomes deaf without any apparent reason! I know it maight be an hw problem, but I would avoid the too slow assistance service if possible, does anybody have an idea? Tnx all, bye.
This seems to be a common problem in Touch Cruise. My Mic stopped working and I took a replacement
The Hardware Quality Of Polaris Is Unacceptable Weak!
Just one month ago my Polaris was repaired and shiped back from UK (mainboard replacement in HTC repair center). It was "SIM not found" HW problem.
...and I have now a same MIC problem!
Now I see - I'm not alone, this looks like amplifier chip failure on the switchboard.
THE HARDWARE QUALITY OF POLARIS IS UNACCEPTABLE WEAK!
Im finish spending my time and money on shipment to HTC repair center.
Today I'm using a BT headset and looking for spare parts on web.
Hate the moment I decided to bay this ****!

Speaker doesn't work

My vox it's three months old, from one week I started to notice a very disturbing behavior. People are able to hear me but I can''t hear them. It seems like the internal speaker is flawed. If I use the miniUSB head phones it works fine and If I turn on the conference speaker it works too. Otherwise it just doesn''t work anymore. I have soldered directly speaker's wires on the board but the problem it's the same. What can I do?
Please, nobody can help me? I have tried also to add reg key wm6SoundFixRegistryImport but the problem it's the same. I'm sure that other people have this problem.
this seems like a hardware problem which you can get serviced by sending your phone to htc.
No, I can't because I haven't warranty. I'm sure that isn't a hardware problem because I can hear a little rustle.
i m facing exactly same problem as well. spearkerphone works fine but earphone do not worki.. if u find any solution then let me know too...
THe problem it's the speaker, I tried another from a motorala and it work! Where Can I find htc parts?
can u guide me how to open the htc phone to reach earphone speaker u mentioned?

Nexus 5: Making-Receiving calls (Microphone and Speaker) problem

Hi Guys -
Black Nexus 5. It has been great in everything except placing and receiving calls. I don't use a headset just the phone directly. But whenever I call someone, people tell me that they can barely hear me. To fix that I literally have to move my mouth right next to the microphone and even then the voice is barely ok. I almost have to shout. People tell me that I sounded much louder on my own phone.
Also while hearing people on the phone the voice is too low. I use the volume control app and have the IN CALL volume on FULL. 5/5. Still I barely hear the other person and if it's noisy outside I cannot. Contrast to my previous phone in which I had to go down to 50% volume otherwise it was too loud.
Is this a defective unit? A hardware issue? Do I need to ask Google for replacement? I am loath to do that since the phone has been amazing in everything else. It's fast as hell and the battery life is super.
I wanted to know if any one has the same problem and whether it might be fixed with a software update or is it just a hardware issue and something wrong with my phone?
Thanks in advance.
Idem for me !
Hi,
I've the same problem with my Nexus 5. I think that it's a software problem because, when I put the speaker on, the problem is resolved. I think that it's due to 2 microphones and noise cancelation... Our voice is canceled ! I hope that Google is awared of that problem and will delivered a fix quickely. Specially that there is another problem with speaker that sometimes sizzles a lot ! I think that i'm going to buy a headset in the meantime. That's really a shame : a new phone that we cannot use to phone ! Even if yes for the other thinks Nexus 5 is great.
Are they other people that are the same problem ? How can we open a case in Google ? How they know that there is really something to fix ?
Thanks,

Did you ask for an RMA? If so, what is the status?
I have the same issue and google has promised an RMA.
Its quite a pain not to have a phone for a week.

I don't think a replacement will help.
There are several other threads already
http://forum.xda-developers.com/showthread.php?t=2518840
exactly the same here... already some news what to do?
This issue seems to have become worse with the 4.2.2 update. The in-call volume is very very low. It's impossible for me to hear other people unless I am in a quiet room (the volume is maxed out). I recall with the stock 4.4.0 - the call volume was not that low.
For whatever reason, using a headset everything is fine. So for phone calls, Nexus 5 is only usable if I use a headset. It's impossible with the earpiece.
Anyone else having a problem with low in call volume? I'm wondering whether it's my specific phone. Everything else is perfect, and the battery life is insanely good. Wondering whether I should RMA.
I too am having this problem. It wasn't like this before the update but outside I can barely hear the other side. I don't make a lot of calls tbh but I remember shortly after I bought it making a call to another N5 and thinking how great it sounded.
Now it's hard to use.
I am having the same issue some days back. They Have replaced with new one..No issues so far..

Hi - did you do anything. I am wondering whether RMA helps in such a case.
I haven't done anything with mine yet I was hoping to compare it to a friends N5 first.
I might try and contact Google.

Replacing headphone jack

Hello,
my headphone jack has recently started to work incorrectly a bit. Sometimes, it detects headphones being jacked in although there are none and thus I cannot talk via the phone (speaker is not working as the phone thinks that headphones are put in). What's more, one of the headphones hardly receives any signal from the jack and just does not play anything, although the headphones are completely okay.
Has anyone of you any experience with replacing the jack? Should I get the phone to some service and let them do the thing or is it doable easily at home? The jack itself is pretty cheap, yet I do do not have the proper screwdrivers or too much experience with so delicate electronics. Screwdrivers are not a problem, yet if it's a rather difficult and risky thing to do, then I'd prefer to give the phone to people who do know what they are doing : )
Also, if anyone has some service manual wherer such replecement is described, I'd appreciate if they shared!
Thanks,
Greg

I just looked up "Xperia L disassembly" on YouTube and found this: https://youtu.be/Ig2ICoM0O4Y
It doesn't look very hard to do, and if something should go wrong you can still go to a repair shop afterwards...

I did find several such videos, but none seems to regard deatching the headphone jack. That's why I was worried if there will be need for some soldering or dealing with very small, delicate elements and I wrote here, as I hoped to hear from some of you, who had already done it.
Should there be no answer, I will try to fix it on my own and post some photos ; )

Can't hear at call and No Sound at earphone jack

I have got a Pixel at relatively cheap price recently. Everything works perfectly except the there are problem at earpiece and earphone jack. I can't hear anything from the earpiece when using the build-in phone app or any other phone application. I originally think of hardware problem. But the strange thing is, if I play record message in whatsapp, I can hear the recording from the earpiece! I have tried some hardware testing app download from google play, some app crush when testing the earpiece while some could play sound with the earpiece. Another issue is there is no sound at the earphone jack. However, when I use the hardware testing, the earphone jack actually work! I have tried to contact google but since I am at a country without google playstore, they can offer no assistance. And they say they did not receive any similar report. Google just ask me to find some local workshop to fix it since I don't the warranty anyway. But if it is a problem with the motherboard, I don't think local workshop can fix without changing a new one. I have try some some of the custom Rom and kernel, but nothing works.
Does anyone have the same issue and got a solution to it?Or Maybe it is a hardware problem? I hear some people it is a manufacturing flaw on the motherboard.
Thanks.
I have the very same problem, again. My old Pixel got that bug and now my replacement as well. Makes me think, that it is Android Pie related.
Have you ever tried safe mode or done factory reset? I have encountered same issue, and got fixed by a local guy. please check my previous thread for more detailed info.

I have tried safe mode and done factory reset but still not working. Where did you find the guy and how he fix it?
I am currently using a Bluetooth headphone and it works alright.
The guy is in China.
After the earphone was fixed and last almost half a year, I got a new issue. I was traveling in Dubai, suddenly the phone became very hot and can not turn on screen. I had to long press the power key to turn it off.
After that, I never powered the phone on
Finally, I found another guy and got the phone fixed.
So, Damn google. I will never buy a pixel phone until it launches months later
