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.
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
Just got a S6 yay!! When I was at AT&T the stupid rep put the ejector tool in the upper secondary mic instead of the sim slot. I didn't think much of it now because when block the lower mic by the speaker to make a call, say okay google, or do a voice memo no sound is transmitted or nothing happens
is the upper second mic just for noise cancellation or did the rep break my mic? anyway anyone can test this to validate?
Much appreciated
I wouldn't even wonder about it. Take it back and exchange it. AoN
Covered up bottom mic and get very faint recording, if any at all. I'm guessing the top mic is for noise cancelation.

Thank you for the reply jondroid2
went back to B&H and got a replacement. Second unit has the same issue. This is the international unlocked SM-G920F. Funny thing went to the Samsung store in Best Buy and the S6 and Edge don't have this problem.
I recently got Nexus 6 and noticed that when listen music the top loudspeaker not working, just bottom.
When making and receiving calls i hear everything like it should.
I'm not familiar with this phone, is this normal or it should be playing music from both top and bottom loudspeaker?
Is the top loudspeaker and earpiece the same hardware?
There is only one loudspeaker at the top.
To me it sounds like a software issue. Have you tried a different music player?
Hmm, i use Youtube app, not tried anything else.
Did the factory reset, its the same, loud and clear from bottom loudspeaker, from top nothing.
I'm sure there is the bottom loudspeaker, here is topic about replacement.
https://forum.xda-developers.com/nexus-6/help/speaker-replacement-t3379395
On my phone, the volume from the top speaker is a bit lower than from the bottom one. But both are active in YouTube.
Which rom do you have on the phone?
What happens when you hold the phone differently while playing. If you hold it with the top to the left, the top speaker should play the left channel, but with the top to the right, the channels reverse.
Rom is stock 7.1.1, not rooted or anything.
I tried to rotate the phone while playing but nothing change, only bottom speaker working, top not at all.
That was the hardware problem.
I disassembled device, it was not so hard because it was already opened in service centre couple months ago, so the adhesive was not that strong.
Removed middle frame, the top speaker is in it.
I checked the speaker with multimeter, and it was ok.
Then I saw the small flat cable where the speaker seats on, and see It is broken somehow (tested with multimeter also).
I had the broken middle housing and managed to peel off the flat cable (very slowly with hear dryer) and replace it.
Now everything working, and the sound is playing from both speakers.
Thanks.
