Hello. Have problems when calling, I can hear the other person, but not the viceversa. So I think is the microphone.
Can someone tell me where is the microphone located ?
It can be changed ?
Where can I find one to buy or something compatible ?
Thanks !

you can prob find it here
Thanks a lot, I looked and the best information was "bottom", this was predictable because you speak in it and can be somewhere else but bottom.
I am not worried about the finding problem, but if you can tell me if it is hard to change, you can change it without breaking any wires and after you need to put it again to their places ? I am asking because I don't have the tools for this kind of operation.
Nobody changed the microphone to a Blue Angel ? At least I need a genuine Blue Angel microphone ?
Regards!
Hey there, You just need a T6 Torx screwdriver to get into the case and the microphone is a small metal unit that slots into the case and has two wires leading to it.
I took a BA apart for the first time this week and it's really easy. Swapping the microphone is as easy as undoing 6 screws, splitting the case then swapping the microphones.
If you're stuck for a replacement then let me know - I'm currently ripping apart a BA with a motherboard fault. The Mic is known to be good.
Cheers!
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
Somehow ( don't ask ) I've manage to broke my desire's microphone. It's a tiny rectangular , shielded , smd mic. As I've heard it has a digital output on the chip . Does anybody know what type is it or the producer , or where can I find it ? I'm willing to buy even a broken MB with the mic on it .
Thanks ,

Might be worth contacting someone like this http://www.globaldirectparts.com/HTC-Desire-Replacement-Repair-Parts-s/6282.htm they seem to have plenty of spare parts and might have a mic kicking around. Failing that it's either spares or repair on ebay (they don't seem to have many and are still quite expensive for a broken phone) or there may be some folks here with broken desires willing to donate to restore one back to its former glory
Thanks for the reply . Finally I've found a broken motherboard and swap the mics. It wasn't easy...
Ive managed to do the same thing... how the hell did you get that thing of and replace it?
Hey guys need some help, need to fix the microphone for a friends phone and i cant find any on Ebay or Google, so if someone can help me find the part, i will be greatfull
thanks
Look for the smallest eletret SMD microphone. That should fit. If it is just the microphone and not the circuitry.
Mouser and Digikey have a bunch and I bet you can find a one-off at octopart.
I was replacing the screen assembly on my M9 and I inadvertently ripped the flex cable for the top speaker.
I tried searching google for any combination of One M9 speaker flex earpiece and came up with just the speaker itself. I even tried to google the numbers I found on the cable itself (though the tear was right in the middle, so number might have been missing) to no avail.
If anyone has any idea how I can get ahold of the flex cable that runs under the top speaker housing, please let me know and thanks in advance!
