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 have a Desire 500 and I replaced the screen and since, I can't hear the dialling tone or the person on the other end, incoming or outgoing, I have to turn on loudspeaker or use earphones. Just to add I've replaced many phone screens for customers without a problem. I've checked the connections etc and all seem ok. just wondering if anyone knows what caused it. Is it a sensor that's faulty or something. The speaker works in music and video etc. Is there another speaker?, as I can only see the one at the top about 15mm long.
I've done a factory reset as I know sometimes you have to after a screen replacement.

I have disassembled the phone myself pretty often,
did you connect these little white cables correctly and also the flex cables?
You probably might need to check the connectors there.

Iv'e not got the phone in front of me right now, but do you mean the back you take off to get to the battery etc?
I know the speaker that sits just below the main circuit board, but couldn't see any others.

You say "These little white cables", so i'm looking for a picture but you haven't attached one.
The only cables are the 3 flex ribbon cables, antenna (2 ends) and the vibrate motor.
And they are all fine.
As I said it rings and plays music and works on loud speaker.
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?
I broke the screen completely 2 months ago. It was working fine before that. The phone was disconnected from the battery for nearly the entire 2 months. I put the screen on today and it worked like a charm. Well , sort of.
During calls , whether that is phone calls or skype calls or w/e , it acts weird. My problem is they can hear me fine but I can't hear them without speaker enabled or headphones/headset. It's almost as if it thinks it has headphones (with no mic) plugged in. It plays music fine on all loudness levels, the dial pad tones and the ringtone all work fine. It only has issues during calls.
So far I've tried disassembling and reassembling the phone , in case it wasn't sitting on the contacts right. Then I tried inserting headphones and a headset mid call and removing it to make it snap out of it , still no change. I tried clearing the phone app data (that was before I knew it happens on skype as well). Lastly I did the system update that was available for it. Any ideas are greatly appreciated.
The earpiece speaker that you hold to your face is separate from the speakerphone/audio/ringer/notifications speaker.
It sounds like your earpiece speaker or associated wiring has become disconnected or damaged.

I didn't know the earpiece was separate. Turns out , because I thought it was all 1 thing , I didn't notice it was glued on the old screen and didn't remove it. Thank you.
So I have a Mi 8 and I apparently broke the screen just while in pocket, though the phone did not really hit anything. (warranty did not cover, they stated micro fracture in screen and user fault).
I changed succesfully the screen myself, but after screen replacement, the phone loudspeaker did not function, no music, no ringtone. Headphones work fine.
So i replaced the speaker unit, did not fix the problem.
Updated MIUI, no work.
Flashed Lineage OS succesfully (for my own fun), did not fix it.
After installing LíneageOS, I noticed when using phone call (gsm etc.), cannot call because the sound is messed up, sounds just like microhone feedback loop near speakers. I don't know did this happen after Lineage or not, as I did not try calling before. Whatsapp then again works just fine, so I suspect something messed up in phone internal call circuit or something (I'm not an expert).
Any ideas on fixability?
