No one can hear me but microphone works - LG V20 Questions & Answers

HI guys, please help me with my LG V20 VS995
Internal microphones (i tested them individually) works when using a recorder app.
Recording is loud and clear but when i call anyone, they cant hear anything.
External mic with headphones does work.
Things i did:
Factory reset. Clear cache, different firmware, root, no root etc ,nothing helps.
V20 has 2 built in microphones. Tried to swap, leave one attached or another no change.
Replaced phone jack with brand new, no change.
Soldered brand new microphone or swapped with the one from the top, no change.
Re-seat chip thats located near bottom microphone, assuming it has anything to do with it.
Few days ago after i soldered another microphone, it started to work and then it stopped working not sure when, maybe after i dropped the phone ?
I am running out of ideas.
I dont understand why when using app, voice is loud and clear but when i call, no one can hear me.
As if there is some kind of switch somewhere that activates ONLY when call is placed.

UPDATE:
I performed another test today by calling my self from skype.
When i steadily buzz directly into the microphone, the voice i head in skype is pulsating from quiet to loud.
I resoldered the mic again, this time using little more solder around the hole and now i can it works BUT only if i talk on the speaker.
I am very confused right now as to whats causing it

Himalaya loudspeaker-sound lost, headphone-sound ok

I lost the loudspeaker-sound in my Himalya. It works using headphones. I think it may have to do with another set of headphone I connected to it, which was not original. Perhaps it put the device on permanent headphone mode. But then again it might not have anything to do with that.
Is there a Himalaya expert in Berlin - Germany who might be able to help me with it? I dread having to send it to the official reapir center, as I expect it to cost a neck and a hand.
Happened to me when I received a call whilst listening to music. I pulled the headphones out before answering the call, and then answered it. I could here them but they cvouldn't hear me. If you plug the headphones in again and remove them it solves the problem. Well it did for me anyway
I tried that. I doesn't do it. It doesn't matter what kind of sound, if Media Player file is played of phone ringing, only the headphones work. I think I need a dotor.
I have read a lot about the problem in others threads. It seems the headphone-jack can get stuck, not making a contact, which normally is being made and which turns the XDA back to speaker mode, when the headphone-jack is pulled out. Hereto:
1- What does that mean exactely? Which part is that, in what part in the on-board jack? If it had been bent out of place, is it possible to bend the part pack (at best without having to disassemble)? (I tried the ramming in and out, no go).
2- I looked at the non-original jack I had used and it is about 2 mm longer than the original. Might perhaps that explain it? Is there a part in the back that could have been bent out of place?
3- If indeed this was the problem (if the jack had been bent out of place, one way or another), would the microphone work? I can record using the dictaphone and the micophone also works during a call.
When we had himalaya's it happened to both of our devices (my wife and I had one each).
It appears the spring in the speaker can come loose. I used to bang mine (pardon the pun) on my palm and sometimes it would start to work. Then we broke the speaker protection shield, and this made it easier sometimes and hard to fix in others.
When I sold it, my friend took it apart as it was out of warranty, and as he is electrically minded, he find the dodgy bit, and soldered it to the device, and now works perfectly.
Yes! Thanks Jasjar. It worked after a bit of beating.
I found a detailed instruction of how to fix it permanently in another thread. Sounds complicated and dangerous but eventually I must do it.

Sorry for kicking the topic, but this was the solution for me. I just poked in the headphone-jack with a little stick and tataaaa... my sound is back!
Sound lost problem
Hi all,
same happen to me, the sound stoped working (on my side it had nothing to do with the phone jack).
After the modifaication which is described in this forum i had still the same problem so i solder the loud speaker directly - still same problem...
After some time i flashed the device again, now it works, so on my side it was a software problem...
The device was 3 month out of power, but i think remove the battery and if the sound appears on startup (on first boot) but later not, then flash the os and it will work ...

Just for reference:
A friend of mine had this 2020, and both Speakerphone and mic were not working.
When somebody called, the ringtone DID sound.
Anyway, bluetooth handsfree worked fine.
All we did was play with the jack, using the stylus! Not even headphones...
And now it works fine!
He says he'll never put phones on it again... lol

Looking for more Info
Hi, please help me find which points in the MDAII Motherboard can I solder to disable the headphones and get the audio and mic back to the MDA.
After a while my headphone-jack is broken from the motherboard and now I only have the pin outs in it.
The device is working perfect, and I can use bluetooth headphones. I just don't have audio in the speaker and no mic without bluetooth.
I hope someone can tell me which of the red points en the picture can I solder to disable the headphones.
I just want to do this temporally until I get a replacement spare part for it.
Thanks
EDIT: 12-12-2007
I got it. Just joining 1 and 3 and you will get audio back to the PDA disabling the headphones jack.
Thanks anyways for reading this..
Did you find out what all the mboard pins are for the jack?
I have a dodgy jack and would like to take flying leads of the mboard jack to an external (easily changed) inline jack. Does any know what the 1 to 6 pins correlate to. I would like to still switch the audio via the external jack. Not bothered about the mic.
TIA.

Microphone does not work only in speakerphone mode

Hi all,
I just got a Nexus 4 recently and I've been racking my brain with what on earth is happening with the microphone.
The problem is that the microphone WORKS PERFECTLY when doing a google search, voice call in normal mode, or voice recording. It does not work at all if I enable the speakerphone during a voice call. This seems to be exactly the opposite problem that others are having with the Nexus 4. I can still hear the person in the call but when I talk, they can't hear me. Not even white noise, just total and utter silence.
I have tried 2 flex cables (trying replaced the initial one whose microphone didn't work at all, at the time I had CM11) and tried flashing everything (baseband, recovery, system) to stock 4.2.2, tested it with no luck. I then flashed everything with the latest version 4.4 off google's developer section and tested with the same issues. I've tried factory resets, unplugging the headphones, and also soundabout and nothing resolves the issue.
When I look at the flex cable and the phone housing, it seems to me that there is only one microphone on the bottom. On the top, there is the noise canceling mic, but I don't think this has anything to do with the speakerphone. Am I wrong? Does anyone have any thoughts or suggestions? I don't know whether this is a hardware problem or some low level software issue.
UPDATE:
I noticed something super strange. If I plug a headphones w/ a mic into the headphone jack, I can actually hear very loudly and in great detail the friction from my fingers moving up and down anywhere the case of the phone, and if I tap on the body of the phone (anywhere, even near the USB port on the bottom) it's like stuffing paper into your ear canals. I can still hear the person on the other end fine, and they can also hear just as clear and loud when I touch the phone body. This phone is a science experiment now. The closer I move my fingers to the bottom of the phone near the mic, the louder it gets.
've tried everything. You also changed the Kernel, I do not know ... Maybe it's a problem RADIO, but I doubt it.
Eventually contact Google support
Typical factory problem....when i bought my Nexus 4 (S/N shows production date is October 2013 so its the newer batch with little nipples and camera lens offset fix) the microphone was dead and i could've only talk through headphones and speakerphone....took it to the repair shop and everything works now. Don't know what they replaced, maybe it wasnt the microphone.

[Q] Mic issues

Has anyone dealt with a dead mic ?
One day out of the blue on 4.4 mic stoped working.
Installed L 5.1. beta 3 and the mic still seems dead (Calls and Google voice) HOWEVER in sound recorder the mic works (picking every single sound) ...
Further more installed the HiQ Mp3 recorder which apparently can use front and or back mic and it works in all configs .(front back and stereo)
Tried different values via engeenering mode with no luck ....
****** Apologies to all this post was misplaced in this forum *********
I guess I should replace the charging board alltogether however I am puzled that the recordings come out clean ......
Anyone with a similar experience ??
(btw sound on wired headset is fine ... bluetooth sound is broken I think due to beta since the bt headset and speaker I tried didnt work)
Phone is Jiauy S3A
Ok Results
The issue was a dead mic (low mic) or rather a near dead mic.
Replacing the mic (on the same board ) resolves the issue (note that you can use third party mics i used asamsung one)
Best test to realise where is the fault
Open the camera recorder and start recording
Close the top mic hole with your finger, start talking in the lower mic and in the end gently (very gently) blow towards the hole.
Repeat on the top hole with the lower hole closed
After that listen to the video
If there is a problem with a mic the voice might be heard but the blow will be almost inaudiable in the problematic mic.
I have exactly the same problem - mic works fine on sound recorder and on the video camera, but Google Voice Search and using the phone does not (I've tried your blow test and it's all fine). This surely cannot be a hardware fault, can it ?
I've tried updating to LL5.1 beta3, but same problem. I've fiddled with the audio settings in the engineering menu, using a variety of values, and turned off the noise reduction without any success.
Any ideas ?

Google voice was the main indicator that the mic was bad ....
Do the blow test again and try as "gentle" as possible and then compare the results, if the uper mic is louder then then mic is dead or nearly dead.
Most probable that you ll need to change your mic
Thanks for your help - can you provide a link to the replacement mic you used (or did you use one from an old phone) - and is it easy to replace ?
Unfortunately I did go to a service shop for the repair, so I dont have a model number, all I know is that he proposed two different types, one was a noname and the other one was made by samsung (so my guess is that any samsung service center can sell you one) .
The process took about half an hour, unsoldering the old mic and soldering the new and the cost was 10 euros ( around 11 USD)
Sorry I couldnt be any more helpfull on that.
I found that, after video recording with stock camera app, main mic stop working for calls. only upper mic working. you can test it with 2 phones in both hands. but I was find simple solution: many people holding phone when taking pictures so the controls are on right side. but if you turn you phone so the shutter button will be on left side, after video recording, main mic still working!!! btw. if you like to take a shoot with control button on right side, just after you finished, turn your phone for 180° and make one more shoot, just to save your main mic for calls. no reboot needed after this action. tested on many roms, KK or LP, happend with all roms and stock camera. so problem is with stock camera app and sensor that give the information to phone to disable main mic.
Well mine was definitely a hardware fault - got a replacement lower board (USB/mic/speakers) and replaced it myself - all good again.
I think i've got the answer. The lower mic is broken for some of us. When we got to the camera app and take a video and turn the phone around it will indeed change the mic and then will use the upper one (still working) in future calls. This is why you can then be heard after when you call someone, but you'll be using the upper mic and the lower mic is still broken. Once your reboot you have to redo this. I'd like to buy a new board (usb + mic) but we cannot find any on internet anymore. Except some sellers on Ebay who are selling it from 150 dollars to 900 dollars (no joke). I guess i don't have much solution except doing that trick and use the upper mic and then try not to reboot the phone.

Primary mic broken, is it possible to redirect to secondary mic?

Hi all,
I am having problems with calling since i bought my n9005 4 years back, people did not hear me speak on the other side, but when i put the phone in speaker mode the sound was just fine on receiver side.
Using different roms from stock to CM13 and miui nothing software related seemed to be the problem (tried all the things that i could find on the net and in settings).
Anyway, so I always been calling on speaker or using my huawei watch.
Now after all this time i thought lets fix it, and bought a new USB / Mic unit which i installed without success.
Since on speaker calls still works great, normal calls only cracking sound, i thought maybe its possible to redirect thru software to secondary mic on top of phone which i believe gets activated when talk on speaker phone?
Thanks in advance.

HELP! LG V20 microphone..

I don't know why so sudden my V20 got problem with it's mic.. There is even a bigger problem which is I don't even know what to be replaced now..
There is 2 situation here :
1 - When in call, with normal mode..everything is working fine but whenever i'm trying to put my phone to loudspeaker mode.. The people whose in call with me is claiming that there is a dead silence when i'm in loudspeaker mode..
Same goes when i'm in Whatsapp Videocall as example, i can hear them but they can't even hear me..
2 - When i'm doing recording with HD Voice Recorder app, the left channel won't even got anything recorded.. Only the right channel does the job..
Same goes with video recording, only right channel does the job while the left channel sound records nothing..
I'll be informed that V20 have 3 mic and it is obviously one at top and one at the bottom while another one is inside the phone nearby the earpiece if i'm not mistaken.. so now, i'll need help.. Which mic should i'll replace to get everything working again?
I'll believe my top mic is broken but which one? The one at the left before the earpiece or at the right next to earpiece? HELPPpPpppPpppPp
nevermind, got mine fixed.. just replace the new mic at the top and now i have back my fully functional V20 again..
i'll never know that phone is using a different mic for normal call mode and loudspeaker call mode.. Now i'm feeling like an idiot because everytime i'll do loudspeaker, i do scream at the bottom mic while it is using top mic ATM.. gosh
I just got mine and no one could hear me, i pushed a thumb tack in the bottom mic hole because it looked like a little plug or plastic was blocking it and and now it works fine, mine was a refurb phone
Bottom mic
My phone mics worked in speaker phone calls but not talking through the regular in-call mic. I had a repair man change the bottom mic today. He had to install 4 mics to get it and the one that worked was out if a Samsung phone! Cost me USD$60. Apparently my phone had water damage before I bought it used. That's annoying but I'm back in business!
I am in the same exact situation. Replaced the main loudspeaker, top two earpiece speakers and still my voice won't come through on the other end of a normal headset mode call. Only can speak through loudspeaker. What part must I replace? I'm thinking normal headset mode sound is received through the pinhole area next to the 3.5mm jack. What part do I replace?! It's getting personal now. I will fix this phone!!
Not counting the two earpiece speakers up top on the mainboard, and the large loudspeaker on the bottom what other speakers are there for me to replace?
