is there any site or place where i could purchase a Lg optimus G microphone pcb replacement i think that mine is faulty it does not pick up sounds unless i speak directly in which it picks up sounds perfectly loud and clear but if i talk normally beside my ear it does not really pick up sounds. If any one else can shed some light on this situation it'd be highly appreciated. Also could it just be microphone needs readjustment or something like that internally , im awaiting my T5 Torx screw set which should arrive on monday and i'll take the phone apart then and see.
For noise killing purposes, optimus g has 2 mics.
I believe one of them is dead, so phone cutting your voice cause detecting it as a noise.
Just send the phone to service center
the thing is i bought this phone from overseas korean version and this phone hasnt been released in australia yet and i dont think it's covered under warranty =/. The mic on the top is the noise cancellation and the bottom one is used for calls etc. The bottom mic can work fine if i speak directly at it or close to it i can even make voice commands with google search no problem but if i hold it further away say to my ear like a normal phone call, it hardly picks up my voice and google search doesn't work anymore. if i call some one and use speaker it works fine. i think the microphone usb pcb flex needs replacement or adjustment maybe some dust or something is stuck idk i guess i'll have to see on monday when i can open it up. Im up for any suggestions on resolving this problem so i appreciate all reply's.

I was able to get my Kaiser after someone at my work dropped theirs and since AT&T won't cover damage they ended ordering a new one and I decided to replace the screen which was BADLY broken but otherwise worked. What I didn't know was that the contacts on the earpiece speaker were being held in be the case.
I am looking to get a replacement 'earpiece', aka conversation speaker, for my Tilt but I cannot seem to find it anywhere online including ebay. So far I have found a few repair shops that would be willing to fix it if I send it in but as I have already successfully replaced the LCD I prefer to do the work myself. Does anyone have the part they would be willing to sell me or know of a company that would sell just the part. I have a bluetooth headset but it would be REALLY helpful to have the earpiece speaker working again since windows can be flaky when it comes to answering the phone using the headset.
if your going to do the work ur self ur going to need a soldering iron and possibly an ohmmeter (electrical evice measeuring electrical resistance ect) u would need to ohm out the speaker in the phone and u might be able to use a headphne speaker if u used a resistor with a head phone to get correct ohms for the speaker to work beacause u need the same ohms or it coul draw too much or too little current from the amplifier and the battery and if that doesnt work speakers in commercial devices are usually genaric made in korea or china u could try speaker from a different phon hopefully a cheap phone, hope i helped in some way
din,
Not looking to fix the component.
I was hoping to just replace the actual component, as I am not trying to fix the broken speaker or try to fit a different speaker into my phone. If I can't find a place to buy the speaker I probably will have to get my work to but me a phone and it will likely will be a Blackberry as that is our corporate standard.
I would need help with my HTC s620. Sometimes the mic works perfectly, sometimes it does not, so people on the other end of the line can not hear me at all or just very-very low. I already tried changing regedit and also used the audio gain and microphone fix .cab files, but the basic problem remained: sometimes the mic works, sometimes not. I made soft reset / hard reset several times, still the problem remains. With my bluetooth headset I always have good voice quality even if the mic on the phone is not working. Altogether this drove me to the conclusion that I need to replace the microphone in my HTC s620.
On Ebay I can buy a new replacement microphone for a few $ but I don't know whether I would be able to replace it on my own. Anyone has any experience? Do I need any special tools for replacing the mic in my HTC s620? Can anyone provide me with a guide how to proceed? Any help is much appreciated.

There's a guide for taking apart your excalibur in the sticky, but honestly it doesn't specify how to change your mic but it will give a pretty good idea of what tools to use to open and re-assemble your dash.
Thanks for the response Mr. Clown. Indeed I would need a bit more specific info on how the MIC is attached to the phone and with what method it can be replaced. I read some forums on other type of phones where only the manufacturer is able to replace either the mic or the full board when it is impossible to replace the mic. As I mentioned earlier on Ebay there are two offers recently on OEM HTC mic for s620, however some forums also mention that even if a separate mic can be purchased, it does not guarantee that it can easily be replaced. Unfortunately I am not a tech expert, so I appreciate any guidance on this issue. Many thanks.
some possible solution
I searched a bit further on more general forums and it seems that I found the answer, so I post it here for others facing a similar problem.
It is not impossible but requires quite an experience and expertise to replace the microphone as it is soldered on the pcb. It needs high temparature heating and then the soldering of the new microphone. You can find new OEM microphones on Ebay (there are recently two offers: 3 - 6 USD price range + shipping), but you have to find someone who will replace the mic for you and who is experienced well and will not destroy your board with this procedure.
Here is a simple description of the process:
1. Set heater of your rework station between 400 to 417 degrees celcius, and air make the pointer of the air knob point aj 9 o'clock.
2. Select nozzle size that is not too big or too small for the mic.
3. Apply ample paste on the mic and direct the heat on it. Remove the mic with metal tweezers gently.
4. Apply paste to the interface of the mic to be soldered and then apply tiny solder on the pads to be soldered.
5. Place the mic correctly on the pcb and apply heat from the opposite side of the pcb, and remove the heat when the solder is melted.
Some have reported that this method really works, however I found no information whether it also works for the Excalibur as the interesting point is the exact place of the mic, so by heating it you will not damage other parts of the board.
I contacted the official HTC service and some other mobile experts, so I am looking for someone that can make the replacement for me... It is recommended that you also proceed similarly.
I hope this info will help.
If the mic sometimes works and other times not, why not trying to re-solder the contacts first? This is much easier than removing/replacing the microphone as you can apply the heat one contact after the other.
Dumb question: You are not covering the hole for the mic. with your fingers from time to time?
Thanks for the reply tobbie. I am surely not covering the mic with my finger or any other body parts ; ) So it must be the mic and not me causing the problem. For the time being I am still chasing someone experienced who could do the soldering for me... In the meanwhile I have flashed my ROM from 3VO.2.80.092509 to 3VO.3.50.033010, just to see whether this might be a software porblem. Flashing went well but problem remained. You are right pointing out that the MIC might be absolutely OK, as it sometimes functions well, and this might indicate that the problem is with the connection of the mic with the board and not the mic itself. However if I take the phone into pieces, then I would like to get it done, so I might still order this tiny mic on the internet. Out of curiosity: does anyone knows whether these mics are compatible with each other or not: I saw many Motorola (e.g.: V3) mics that look exactly as the HTC S620 mic, but I don't know whether they are really the identic.
For the time being I use my BT headset till I (hopefully) manage to solve this issue.
For a start, I would stay with HTC devices. All the older ones I have disassembled (typhoon, hurricane, tornado, excalibur, vox) share the same microphone (at least from the looks). Earpiece looks identical for all except the vox, ring-speaker looks identical for the 3 candy-bars while excalibur and vox seem to have the same as well.
Buying spare parts is usually more expensive than getting a used device with a broken screen or otherwise damaged. I have two definitely ruined boards (Tornado with a dead LCD interface + Hurricane with intermittent shut off) and some Typhoon parts that can not make a complete device.
Never soldered anything on the PBA - it is really delicate and if you spoil anything the board is gone. Possibly try to record something with the PBA accessible and apply some force to the mic while doing so. This should reveal if there is problem with soldering.
Many thanks for the help tobbie.
I will give a try and see how the mic would respond for such a "treatment". In the meanwhile I found a funny forum response from a guy who replaced a PCB soldered SonyEricsson W880 mic without a rework station, by just using a gas butane torch:
"I just managed to replace it. It wasn't so difficult.
First you have to unsolder the mic on the PCB (I used Gas Butane Torch from B&Q as I havn't got a Rework Station)
After that I found some old mic laying in my draw from samsung. I soldered it to the PCB using two thick copper wires
ps. If yo damage a track on the PCB you can solder a positive to the capacitor on the other side of the PCB."
Well it sounds a bit weird, anyway I would still go for an experienced expert with a rework station and proper equipment for replacement.
Danke und tschuss
Last night I dissambled my HTC s620 (it was a bit harder then I thought) and got to the mic, which is under a small rubber case, I cleaned a bit the surroundings, checked the contacts, but from the first sight everything seemed to be tight and fixed, still I pressed the mic a bit but no better mic functionality, actually now I can only here everything said in the mic very-very low and from last night there was no occasion when I could record with normal sound level. This might still indicate bad contact. Anyway, I will get now a replacmenet mic on Ebay and try to replace it. Will report whether it has really solved my problem.
The mic has the following numbers on it: S777 261, I don't know whether these types of mics are really compatible (I assume that they are - not only within the HTC brand but also with similar Motorola mics), anyway I will not go for a cheaper V3 mic but buy one which is advertised as an HTC S620 mic.
Same problem.
I've been using my excalibur for 2 weeks and, last night, in the middle of a call, my microphone stopped working. completely. does anybody have any idea of what i can do to solve this problem?!
please, i'm desperate.

You try to check the headset jack may be the cause of it
My phone took a quick swim the other day. Everything works except when I make calls it causes tons of static and I can hear the other person but they can't hear me. The weird thing is with headphones in or on speaker phone the phone works perfectly.
I thought maybe the ear piece speaker was to blame, but I bought a new one and replaced it, and still no luck. Any other thoughts on what may be the issue?
Thanks!
One of the connections came loose to the mic probably.
Happened to me on a old school PS2 headset, I could hear other people and they were all yelling saying I was hurting their ears.
Took the headset apart and sure enough found the unattached connection.
them not being able to hear you when normal call tells me the main mic has failed.
Normal calls use the second mic for noise cancelling only. Speakerphone use either, or just have them swap roles. I can't really tell. The main mic is part of the usb connector assembly. try reseating it first.
I just reseated it i believe. I took the screw out at the bottom of and removed the bottom block (of course after taking the phone apart). Still same staticy noise.
How do I have the speaker phone switch which mic it uses? Maybe I can pinpoint the issue and then order a replacement part?
I know this is an old post, but any progress on this? My nexus is having the exact same problem. I've already replaced the charging port/mic cable and the problem is still there. Thanks
That is all I had to do to get it fixed (replace port/charging + mic cable/ribbon at the bottom of the phone).
Alright, I ordered 2 replacement cables so I'll try another one when I get home later. Thanks for responding

I have this mic issue, and some other ones. After 1 year using this phone, I had no more vibrator, and bottom speaker.
So, recently, I opened the phone, and replaced many parts: both speakers (I thought it could not hurt - i was wrong), USB plug, battery, stickers.
After just a month, bottom mic is dead, and upper speaker.
I have read somewhere that the phone works in loud speaker mode because then it uses a second mic near the cam (to be confirmed). For now, I can not use the phone in normal mode, and, many apps like Shazam (and voice recognition) don't work (skype and phone can work in loud speaker mode, or use the BT earset; Shazam does not seem to be able to do so).
Most parts come from Ebay; I also had issues with Amazon (both marketplace and premium).
No local store can sell HTC parts.
The national official website can change parts if I send them the phone, but refuse to sell them seperatly. I refuse to send my phone, because it would take 2 weeks, and they would probably erase the FLASH.
Where can I buy good quality HTC parts for this phone ?
It's a shame for such an expensive phone to be so fragile. Many people complain about broken mic after a few weeks. Vib also broke for me. And after changing them, half new parts brake after 1 month. Plus, the bicolor LED is really missplaced: just in the middle of a stupid grid, have to turn the head around the phone to check if it's on or not (I drilled a hole in it to see the LED from all angles).
I dont think there was an issue initially when I got the phone 2 months ago. Now when you take videos there is a horrible screech on the the video. And people claim they can barely hear me during calls. I have seen the others complain in youtube but no fixes. btw I have another phone that does the terrible screeching during video recording but its a cheap ass umidigi. Yes I have done a factory reset. how about a usbc mic that mounts flush to the bottom of the phone, anyone know of anything like that?
For USB C I have no idea if there is, I would think so. What you could try is using a TRRS tie-type microphone through the 3.5mm jack. That's the only one I can think of. Did you ever wet your cell phone? Still it would seem strange to me.

not that i know of(wet) but i read that many people say its just a ****ty phone. wtf did i not see these reviews! definately done with lg's now. my g5 was kinda good but the GPS sucked, known hardware issue.
It's known that the microphones for recording video are bad (for music, anyway, voices seem okay, except perhaps a bit sibilant). I've never had complaints about how I sound during phone calls.

I have had the All Generations G except the Optimus G and G7 (I currently own G8s ThinQ) and I never had that problem you mention. It will be something of bad luck in your case because I have not been notified of annoying noise in calls.

yeah i actually loved the g5 but couldnt play pokemon go, lol well sometimes it was an advantage with a glitchy gps i could be quiet far from a pokestop and hit it....however if i was right no top of it not so much. there are lots of comments on this site about the g5 and "fixes" for the gps which rarely worked.
fixed it. First I remove the charge port board it contains the mic. I tried recording with the board removed, noise still present, damn its the mic on the main board. After trying to figure out how to disable the mic, couldn't. I opened it again and held my solder gun on the mic long enough to melt the solder and remove the mic. problem solved. I guess these "advanced" mics were fighting each other for control, lol.
