Milestone Proximity sensor and Microphone not working - Motorola Droid and Milestone Q&A, Help & Troublesh

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.

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.

[Q] Speaker mystery

Hello everyone. A few days ago I started having a problem with my cappy, and I can't put my finger on the cause.
My speaker stopped working. Partially. When I'm on the phone with someone, I can't hear anything from them. If I turn the loudspeaker on, I can hear them just fine. Phone rings and notifies me of smses but I can't hear anything else. I don't hear music or video playing on the phone or the alarm clock.
In short, Working: In-call loud speaker, sms and calls.
Not working: everything else - music, alarm clock, in-call sound.
In summery, I can't decide if it's a software or a hardware problem.
I'm running CM 10.1 M2 with devil 4.2.
I should also note that I disassembled my phone to try and apply the
"loosen the screw" fix on the speaker assembly with no luck, nothing changed.
I think both. Earpiece and speakers are different devices.
Hardware - earpiece, software - speakerphone alarms, music etc.
One simple idea: take a piece of something thin, like needle and clean 3.5mm port.
I had almost-same issue 1 year ago. just dust formed wool and began shorting contacts inside port.

Thank you for the reply. Let me get this straight, you suggest I clean the 3.5mm port even though earphones work fine? (I haven't mentioned this but with earphones, everything works properly).
earphones = headphones = ear plugs? no, not this.

Your phone has 2 speakers - front, and back.
As i understand, your front speaker (for usual calls) is malfunctioning.
And if you turn SpeakerPhone in call, then you can hear oponent?
Try to clear port, this wont hurt. But might fix issue. You don't need to disassemble phone, wooden match will do too for cleaning.
Just nothing wet, and don't do rough movements inside port.
It's a bit fragile.

When it happened to me I had to re-seat the ribbon going from the speaker to the sim board. it is very sensitive and I had to do it twice before I got connection back....i just banged the phone around too much and the ribbon lost contact....After the ribbon is seated correctly then just don't tighten that screw too much as it will unseat the ribbon again.
So, gosha.
Anything fixed?
I did as you suggested Yuna, I tried cleaning the 3.5mm port but I'm afraid it had no effect.
Then I disassembled the phone again and as Rmntruexjr suggested, I tried re-seating the ribbon connecting the speaker module to the circuit board several times while the phone is turned on and I'm trying to play music throughout the ordeal. That didn't help either. As previously, ringers work and the loud speaker works but alarm clock, music and the front speaker for calls do not.
Does anyone know if the music and alarm clock are being played by the front or back speaker?
If they are played by the front speaker then the problem is obviously a malfunction in the front speaker and I should just get a new one. Otherwise, there is something weird going on and the back speaker only plays some of the sound and then I can't explain it.
music is played from back speaker.
stupid q: did you checked volume levels?

Yup. Just to make sure, we are talking about System Settings -> Sound -> Volumes?
However, your question has just made me recheck all the settings and apparently the alarm clock does work!
The current situation is music and front speaker in-call sound doesn't work, but back speaker in call sound works and so do all of the ringers, notifications and alarms.
So, if you play music - no go? Try volume buttons in-playing.
There are 4 different volumes, and 1 hidden.
Front speaker might be broken. Try stock rom, if not helping - service.
And also in call try to adjust volume.
Try kernel with/without voodoo sound. Install/uninstall voodoo sound.

No go on the music, same with the volume buttons in call.
As for the kernel, I don't think there is a voodoo and cmc version for the 4.2 Devil kernel (for whatever reason), I only found one version of it - set me straight if i'm wrong.
I'll try rolling back and flashing CM 10.0, i'll see if it helps and report back.
Servicing the phone here is probably out of the question since i897's don't exist in my country, only i9000's so if it comes down to hardware, i'll just order a new speaker module from ebay and install it myself.
But to order, you must be sure its speaker itself.
Sounds like software issue now...
Crazyness...
Рус?
I'm actually surprised the ribbon trick didn't work. I know your issue sounds messed up, but what you describe is detail for detail what I was seeing. It made no sense what so ever to me how for instance no front speaker in call but still speaker phone worked, but then no music, yet alarm works....(i think the ribbon can lose contact on just the right side so you only get some things working).
Sorry it didn't work for you, but it might be worth it to try again if you exhaust all other possibilities. If you do, keep the phone off while trying to seat the ribbon(and make sure the little black fastener is all the way open(up) when inserting the ribbon). Then to test without putting it all back together I used an elastic to hold the battery and tested that way........
If it really does turn out to be the front speaker/jack/sensor unit, I found one last month on ebay for around $2 for a cappy with a bad Jack and it was fairly easy to replace.
For what it's worth, mine stopped working the other day for no reason. Hit it, and now it works. Just something to try (not too hard of course, just a light tap on the hand )

Same issue....That is how mine started...I dropped it one day then I went to play music and the sound would just cut out for no reason it seemed...I could shake or tap on the phone and it would come back on for a while, then nothing again....for me, it was the speaker ribbon.
Ahh that's kinda crappy (no pun intended). As soon as I hit mine, it worked the whole time the phone wasn't bricked .
PS I keep getting outbid on these alltechwholesale auctions by the same guy -_-"

I didn't realize earlier that you had the EXACT same problem so I'll give it another go. It's a good idea with the rubber band, I had to hold the battery throughout the ordeal last time. Even if I order one of these units on ebay now, it'll take about a month to arrive.

I'm afraid I tried everything I could which relates to the common Cappy speaker malfunction, that's not it i'm afraid.
I spent 10 days in the desert prior to this malfunction so it's very possible sand caused something (there is sand inside the phone ) or I may have dropped it or something. I didn't want to mention this earlier so I don't throw you guys off straight into a hardware issue.
Well imo hardware is usually an easy fix, so long as it's not the main board (at that point it'd make more sense to just buy a new phone). Open the phone up (don't be scared, there's a tear-down guide on this section w/ pictures), take a can of compressed air, and lightly go over all of the parts inside the phone. Take care not to knock anything out of place. You may also want to re-connect all of the ribbon cables, just in case one came loose (very VERY high possibility). If you need any extra help you can pm me here or shoot me an email (I work in IT and do hardware repairs all the time ).

[Q] Got to use loudspeaker or earphones to hear somebody I called.

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.

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.

[Q] I9000 electronic hardware help (earphone piece)

Hello
I got an I9000. A few days ago I dissasembled the phone to separate the glass from the frame to fix the "home" button.
I was able to remove it without breaking the screen and fixed it. When I assembled everything back together I noticed that the earphone doesn't work and I can't hear what the other person says in a call. If I enable hands free it works well (uses the main speaker of the phone) and if I connect headphones to the audio jack it works as well.
Microphone is working fine (using the audio jack or using the phone's microphone).
I tried to replace the earphone-audiojack-light sensor module and it still doesn't work. I tried 2 different ones with no success.
The light sensor / proximity sensor works good as well. So I don't think there's a damage on the motherboard or the socket itself.
According to the I9000 technician manual it says to follow a few checks for this module that I attached on the attachments.
The components it asks to check are:
U207 - IC-CODEC
UCP200 - IC-MODEM
HDC302 - HEADER-BOARD TO BOARD
Surpsingly I am sure those components are used for other features of the phone. For example the IC-Codec must be the audio codec used to play sound. Sound works perfectly on the other speaker and on the audio jack. IC-MODEM is probably the chip that holds the modem.bin firmware of the phone, so if there was a failure with this chip I think I should have no signal, and I do. HDC302, well, could be, I wonder why tho since I've been carefully with this and I have dissasembled this phone a few times already with no issue.
Could you help me? How do the tests indicated in the manual? I only have a multimeter, but not an oscilloscope.
Thank you!
Hello
Seems this is a tough question. Do you know where I could find information? Maybe another forum that it's more into mobile hardware stuff?
Thank you.
Hello
After checking the pins with a multimeter I noticed that the pins 11 and 13 from the earpiece were not in continuity. Replaced the piece (a few times because all of them were broken) and phone is working again.
Thanks.

Question Zenfone 8 problems with speakerphone during phone calls

Hi,
Has anyone have such problem with speakerphone during phone (or whatsapp/viber etc) call that
All MIC's passes tests OK, record and then play my voice very well and loud.
But when I call someone or someone call to me and I active speakerphone to put phone away from my ear - there are mess like echoes, some robotic voice like signal excitation and interference started each time for person on the other end of the line. Person hears himself more often than my voice. So it's impossible to talk normally on speakerphone. I hear companion very good, but for him it's mess. But if I deactivate speaker and use earphone (in front of my ear) - then everything is ok for me and person on the line.
Does anyone know what could be wrong? Problem persists on each FW which means that problem is hardware. I checked all mics in ,12345+= test utility. Every single microphone is ok. But it seems that when they work together - sometihng is going wrong. There are 3 mic's in this phone. First one is located on board 90AI0060-R10010 (bottom left corner), and this part can be replaced, it doesn't cost an arm and a leg. Second one is located in top upper part on main board and it looks like it can only be repaced by replacing motherboard which is cost a lot of $$$ which is not acceptable for devices not covered by warranty anymore (unlocked BL). Third mic installed on board 90AI0060-R10020 under back cover (where rear camera is located) and also can be replaced, price about 10USD.
But where is controller/unit which operate by these mic's?
Is there anyone who has or had such problem? What part(-s) were replaced is service under warranty?
Hi
I hat similar problems. I tried a lot of adjustments at the apps and the phone. Set the phone to factory settings. Nothing helped. Even the upgrade to Android 12 didn't change anything. Finally I sent it for warranty repair to Asus workshop and now I am waiting to get it back. Hopefully tomorrow I can tell you the result.

Ok, please also let me know (if possible) what part(-s) will be replaced.
There are 3 microphones in our phone. And I guess two of them are operate during phone calls on speaker. Main mic on sub-board which is located at the bottom of phone and second one - noise-canselling MIC which is located on motherboard (top part of phone).
Hi, today I've got it back. The workshop protocol says they made a firmware reset (same I already did before and told them). And the result is, the fault is still the same. This was second time I sent it for repair. First time the WLAN module broke down. They changed the motherboard and after getting it back from the asus workshop the the speakerphone function didn't work any more. You can see, there are absolutely specialist at work.
