I thank God that our phones can be opened. My speaker stopped working today, so did some homework and watched a few videos on how to take the phone apart. I cleaned the speaker connectors and any other connector pads I could find inside the inner case plate (top and bottom speaker panel) and on the mother board and my speaker came back to life! I thought I would have to buy a new speaker panel. Saved some cash! I cleaned it with alcohol and canned air.
Update.
Speaker stopped working again. Did more investigating and some guys (in the NEXUS phone group) noticed that if you pressed on the back of the phone near/below the camera lens , the the speaker would work again. I tried this and found that if I took off the back cover and pressed directly left of the button area (UP/DOWN VOL-Home button), the speaker would come back on. So I removed the inner back cover and placed six small layers of electrical tape in that area to provide pressure to that area when the inner cover is reattached and screwed in. Well it's going on day two and the speaker works every time. Don't know if this is a great solution but I got my phone working again and avoided buying another 600-700 dollar phone again. Hope this helps somebody.

Would you have a d-pad as it seems that they get worn on the inside.
Taking it apart and removing the dust has not helped.
However if I look at the back ruber part of the d-pad I notice that it has a raised button were each of the contacts are. My down one is now close to being flat. A dab of glue did not stick to the ruber as it fell of when I was putting it back together again.
To make it worse for me is the fact I was given a replacement BA as it was no longer needed and that too has the same problem (which would esplain why I got it for free in the first place.
People can't hear me well, no matter what i do, flashed different roms (various cm7.2 and oxygen), wipe, etc...
My mic gain is very low and ppl can't hear me well, guess i could open my phone but i can break something :S
Has this happened to someone??
As a last resort i'll do a kdz reset
It's either a kernal problem or hardware. If it's a hardware problem, then the microphone connector is most likely disconnected partially, or broken.
Try an app like Iris or Vlingo and see if it hears you

I've tried different kernels, also tried KDZ flashing, and nothing, mic works but theres too little gain and so no one hears me well , im shouting all the way for ppl to hear me XD
Guess its time for repair service?
EDIT1: After opening the phone following carefully a disassemble guide and then put everything in place seems that mic improved a bit,
Can anyone tell me how far can you record a video or file without loosing volume gain (in mic)
Change the Mic from mobile repair shop

Optimus V microphone fix how to
This is how I fixed the microphone on Virgin Mobile's Optimus V . Note: this will also work for any other optimus phone.
Problem: My microphone worked, but it was hard to hear me. I would have to cup my palm around the microphone hole and speak loudly for anyone to hear me.
Fix:
You will need to open the phone completely. Take off the black cover on the back of the phone, followed by the SD card, and battery. Now you are ready to begin.
1- Remove the 6 tiny screws (my screws were very difficult to get off, this is how I did it. 1- found the CORRECT size screwdriver, 2- pounded the top of the screwdriver twice, lightly. 3- used a pair of needle nosed pliers around the screwdriver and turned it using that (your other hand should be holding the screw driver in place). This will loosen up those difficult tiny screws.
2- Pry open the phone slowly and carefully.
3- Remove the buttons.
4- Remove the 2 tiny screws at the bottom of the phone.
5- Lift out the mother board from the phone's clear screen. (this doesn't need to fully come out. Just enough to get into the microphone at the bottom of the phone.)
6- The little hole for the microphone is actually a a foam with a tiny hole in it that carries sound to the microphone on the motherboard. You will remove both pieces of foam tubing for the microphone. The first one is simple to get out, just pry it out with the screwdriver. The second one I used a tiny paper clip and inserted it into the microphone hole. Then I used the screwdriver to scrap it out.
7- Once it is out, blow into it removing any dust.
8- Put the phone back together. (2 screws at bottom, buttons, snap backing on, six screws, battery, SD card, battery, and black backing.
YAY! Now it is fixed.
What happened was during the course of time and dropping it a few times, the microphone tubing's alignment got off. So what we did to fix it, removed the tubing completely. In actuality, the person on the other end should actually hear you better than the factory alignment.
Note 1: Since there is no longer tubing, dust can get into the microphone more readily. Please make sure you clean the inside of your phone every so often.
Note 2: I am not responsible for anything you do to your phone. I am simply telling you how I fixed my phone.
Good luck! =]

I have an Optimus V and this very thing happened to me... In my case instead of foam, it was a rubber grommet. I just pulled it out. I tried re-positioning it but it sounded SO much better without it that I left it out. The hole is SO tiny I can't imagine too much dust getting in there, but I am considering perhaps placing a small screen over the hole, inside the case. Interestingly, I don't recall dropping the phone and can't think of any reason why this happened all of a sudden - maybe the adhesive that holds the rubber just shrunk enough to let go? I dunno. Anyway my phone works great again.
I replaced my screen/digitizer/bezel last night. All went well except the power button wasn't sitting as high as it was originally. Took it back apart to adjust the tape and the button, put it back together, worked great. I tried to make a call this morning though and at first didn't think my call would connect. Pushed the speakerphone button and it was actually ringing. Tried to make a couple more calls but there is no sound from the earpiece speaker at all. I did read somewhere that someone ordered the replacement screen and it didn't have a speaker in it but I don't want to have to pull it all apart again just to check if it exists. All of the ribbon cables and such were there when I reassembled. Could someone tell me which cable it is that connects the earpiece speaker so I know where I should start looking for the issue? Thank you.
Never mind. I couldn't take waiting any longer for a response. I took the phone back apart to find that the earpiece didn't come with the new assembly. I did find 2 threads mentioning that it might not be but no where was it part of any dis/assembly videos that I watched. If you do get a new LCD screen/digitizer/bezel assembly make sure to take your old earpiece out of your old bezel. I read that someone else destroyed theirs trying to remove it. I took a razor blade and slid it between the earpiece and the bezel and it pried out without much issue. It is only glued in. No ribbon cable, just 2 little contact prongs. Make sure to save yourself the hassle and check your assembly before you reassemble you DNA
I have had this phone for a couple of months. I bought it from someone who upgraded and sold me the phone the next day so I have no warranty.
When vibration intensity is maxed the phone makes a loud buzzing and crackling sound like loose plastic.
I thought my vibration motor broke so I replaced it and it improved, but it still does it.I turned it down but I am trying to sell the phone and I can't in good conscience sell the phone if it buzzes when the vibration is maxed.
Should I get another motor? Does anyone else have this issue!
I had this issue and it bugged the crap out of me. Take the back off, all the screws and pop the plastic housing off. You'll see the motor om the top left. I just pressed down on it firmly to get stick it back to the tape. Put phone back together and you're good!

I have done this 3 times today. Dismantled, removed mobo, pressed it as hard as I could w/o damaging it and screwed everything back in really tight. My OEM vibrator (?lol) would rattle the thing even at the lowest volume. I dismantled it and pressed down with that one too and again, it rattled hard. I am running out of ideas. Could I really get two bad motors? It doesn't really make noise until it is all put back together, then it starts.

You might want to check your back cover then. maybe it's not snapped in all the way. You probably would be safe by putting a little tiny piece of foam on the motor with some adhesive. get some 3M double sided tape the 5mm kind. I would think this would be OK...
Hi everybody,
this morning I've been quite dumb: trying to insert the sim into the newly arrived mate 20 pro, I inserted the pin into the left bottom hole instead of into the correct one on the sim slide...
Does anybody know what are those two holes? Microphones? May I have broke something? For example the waterproof integrity?
I installed a testing app and tried to register covering alternatively the two holes and it seems that the phone correctly register my voice...
Please help!
Regards,
Enrico
We really need to be careful with this. It's so easily done. Just taken double care myself a few minutes ago.
I read about this on a review.... yes, 2 microphones on the Mate 20 Pro, hole for each, one very close to SIM hole. The reviewer noted hoping there's some protection to the mic as this would happen.
There is a third hole on the top, is that another microphone?
I'm not sure I damaged something: when I phone, on the other side my voice is well received, besides I re-tried to insert (extremely slowly and carefully) the pin inside both the bottom holes and it find something hard at the same depth, so it seems that nothing has been perforated.... but, I really would like to know where to find technical schematics or tear down videos to see how these two microphones are mounted and which is their function.
If I try to register something with the recorder app and I tap alternatively on the left hole and the right hole, only the second tap is registered... so two are the cases:
1) I destroyed the left microphone, but the right one is sufficient for any application to work correctly
2) Nothing is destroyed, but the left hole is something else or the microphone inside is used for other purposes (noise reduction?)
Does anybody know where to find the phone schematics?
Thank you everybody!
Think all three are for microphones and noise cancelling. In the dialler on speaker you can change it to all direction or bottom part of the phone so I guess it needs 3 to work correctly depending what option you pick.
You may have damaged the mic. That hole near SIM eject tray is a mic....so record your voice or make some phone calls and see if you can test out with someone else on the line and test if theres any discernible differences by conversation.

On fixit I found a tech guy that disassembled the mate 20 pro.
It seems that the microphone cannot be reached from the hole since it sits on top of a little motherboard and is also protected by a gasket the is perpendicular to the hole. So, it seems that the pin only reaches the plastic of the mid frame.

Lucky me - also pushed a needle into the wrong hole. Thanks for sharing this!

I did the same thing too. I didn't realize there are two mics underneath until I found the pin cannot push the sim tray out.!!!!
