Ok so the digitizer on my milestone went bad about a month ago, i ordered one off ebay and installed it myself. unfortunately while doing so i ripped the flex ribbon that has the sensors attached to it. went on ebay again and ordered that part and installed it, didnt destroy anything this time.
put the phone back together and everything seemed to be working fine, then i got a call, the person on the other end couldnt hear me and the proximity sensor caused the screen to go blank even before i put the phone to my ear
if i put the phone on speaker phone the person hears me but its very low im told, inserting the headset works fine, person can hear me perfectly.
i tried doing a recording with the phones sound recorder and all i hear is a hissing type sound when i play it back, i also downloaded an app to test the proximity sensor and its showing a distance of zero and when i put my finger near and further away from it its still saying zero.
tried doing a battery pull..hard reset, reflashing the froyomod that i have install and nothing seems to work, could this be a defect with the flex ribbon i bought? would this ribbon affect the microphone?
any help would be appreciated
Thanks
I also damaged the flex ribbon while changing the digitizer... where did you get the ribbon? Anywhere in the EU?
got it off ebay..it was shipped from china
bump........
I have the same problem and it's the effect of the digitizer replacement. Light can get access to the sensor between the digitizer and the sensor. If you press the left upper side of the digitizer the proximity sensor is working again, very annoying during calls. I tried to put some spongy tape behind the sensor and the metal backing plate it's better but not perfect.

Luvkillin, have you been able to fix this abomination of a mobile phone? I had a malfunctioning digitiser and replaced it, after that the microphone stopped working so i thought that I had broken the microphone. Changed the audio pcb and turns out that its still not working. My prox sensor also doesn't work but with all the other problems this is just a nuisance.
I found that motorola couldn't be arsed specifying the second microphone that is on the logic board and some acting as noise cancelling. I installed a db meter app and picks approximately 25db except when the phone rings which goes to 65db. So if the noise cancelling module is disabled by software, the mic could work without changing the logic board.
Did you manage to fix it?

No i havent, its just sitting at home in a drawer
i also installed a db meter app and got a consistent 16-19db when the phone is not in use. i assumed that it was too much of a coincidence that everything was working before and as soon as i changed the cable and digitizer they stopped working. plus the digitizer and cable i bought was for the milestone a855 and i have a a853. when i checked they seemed to be the same but i guess not.
im planning to just buy a new digitizer and cable for my phone specifically and see how it goes.

I believe its the noise reduction microphone damaged at some point in the disassembly. Did you check the 3 gold pins on the right upper side of the logic board?

Yea i did. dont see any damage at all to the pins or the board
The same problem here. I've changed digitizer and my proximity sensor stopped working. So I thought that I broke it during the work. I've ordered new main flex with the sensor. It was much better but still not perfect. But microphone went down. I think the problem is microphone board or the flex cable that connects it to the mainboard. Did you manage to solve the problem? I've ordered new mic and new flex.

Nope..still no fix
did that fix yours?
anyone knows how to disable to noise cancellation microphone?
Hi guys,
to refer to the proximity sensor issue, i'd like to point you on my old post over here:
http://forum.xda-developers.com/showpost.php?p=9810999&postcount=8
Please check for the rubber...
Concerning the microphone, this might be related to the electrical contacts of the mic.
Please make sure again that everthing is right in place.
Would not harm to check the flex cable connectors as well.
Regards,
scholbert
Solved problem
Hi to all,
I had problem with my proximity sensor, it didn't work at all. (I had cm7, cm6 and cm9 rom)
I installed stock rom and it works again. ))
Microphone problem
Hi all !, I'm having a similar issue after change the digitizer, I'm not having any issue with the proximity sensor ... but is not the case with my microphone, when I answered a call my voice is heard into the speaker and the other person didn't hear me .. somebody found a solution to this problem ? Thanks all !
Had simular problem after replacing digitazer. if i press hard on upper side of the screen, then for some time everything comes to normal. So i desided to heat it up using a hair dyer for about 10 minutes, than press as hard as i can and wait till cool down. now everything is fine.
I seem to have a problem when using the speakerphone. I can't be heard on the other end. Regular calls are fine.
I'm using Cyanogenmod 10.1.3. As I understand the phone, the regular microphone is at the bottom edge on the keyboard part of the phone. There's another microphone (noise cancelling?) on the top edge near the power button. The speaker is the slot on the back. Does that have a microphone function too?
I recently replaced the earpiece like so many other people have. Could I have disturbed something near that top mic?
I was wondering if there's a way to test the mic near the power button.
Thanks,
Paul
Hey Friends
i got a Xperia Z from a Friend who wanted to throw it away cuz some parts were broken.
i could fix it to the point were everything is working except this:
Cameras (not found it says but its connected, so i guess i need new modules?)
Microphone (in the service menu test, secondary microphone is working, only the "main" isnt)
Bluetooth couldnt find my bluetooth headset too, but thats not that much of a problem.
Flashlight LED
So my main Question is, if i replace the whole flex cable for the power btn and volume buttons (where the microphone is located?) itll work again?
Hello everyone, I bought bodies for ebay, I arrived in excellent condition, only the microphone does not work, even when I turn on and set up the assistant for the first time, the microphone does not hear “ok Google”, I tried to shoot video - the upper microphone works, the bottom one doesn’t, I inserted the headphones and checked it on the recorder - With headphones through the microphone of the headphones he writes, take out, the native microphone does not work.
I tried to enter the service menu and update the firewood (it turned out that it was not in g8 or I'm bad)). The phone itself without visible damage to chips, etc.
I updated the firmware to the latest.
The campaign will have to be sent back to the seller)))
I ask for advice!

how do we test the microphones? how do we know which app uses which microphone?
in my case, the mic starts working after 10-30 seconds in the call (sorter if I start the call, longer if I receive)
Whatsapp and audio recorder work fine but google assistant and shazam are deaf
I tried resetting the phone and starting in safe mode to no avail
test all microphones with my Huawei app. Some apps use one of the left or right microphones at the bottom. My mate 10 pro, the bottom one had the microphone on the left broken. That's how I know.
thank you, recording from the bottom mic does not work, still don't understand why it works in call after 10 seconds or so (switch to the top one?).
I have The same problem. And it started after update to emui 11. If its a hardware problem IT should happen Evan after IT stars working. Im trying to reflash my device but i had no luck. Erecovery stops AT 19% download. Fastboot HiSuite says device its not supported.
problem is 100% your bottom (main) mic. The top mic kicks in about 10 seconds into the call and that's how they will start hearing you. If you start the call in speaker I'm sure it works perfectly. I have changed this on my p30 using a part from [email protected], and can confirm it works.
I have the same problem with the microphone on my P30 Pro. Does that mean that all applications (camera, voice recorder, whatsApp, loudspeaker ...) use the upper microphone? The microphone below is for calls only? When I answer normally, the microphone turns on in 5 seconds. And when I answer the loudspeaker, the microphone works immediately. When I used apps to record conversations, nothing is heard. Neither I nor the caller. I tested everything through the My Huawei app, and it only reports an error for that main microphone. If I replace the main microphone, will the problem go away or is it a software error?
Having issues with the lower microphone that's been listed all over the net, ie delay in hearing me when answering calls and google assistant not hearing me.
Two lower sim/memory/microphone boards later still didn't fix it. For me swapping out the USB ribbon connector has cured it. Just in case this helps someone.
Try this:
P30 Pro Failed Lower Microphone Issue - Workaround possible?
I really like my P30 Pro but this last week callers have been complaining they can't hear me all of the call. It seems to be this happens for the first 10-15 seconds of the call and then sporadically throughout the call. I have searched the...

In my case I replaced micro PCB only but does not work. Will try replacing USC charging (and more) flex and post the result on that post.
