Ear Piece speaker on TB

I don't know if I'm the only one but I am on my 3rd going on 4th Thunderbolt. The problem is the ear piece speaker as soon as I use speaker phone once or twice it seems to kinda blow out I guess and everything is a lot lower even with everything turned all the way up and some of the sounds that come out of that speaker are so low or totally gone after that happens. Like the lock and unlock sounds cant be heard anymore unless you have the phone to your ear and even then its a really dim barley noticeable click. And when on calls everything is lower out of that speaker even with the volume turned all the way up. And its only with that speaker the back one is perfect.
no problems
yea I just don't know everytime I use speaker phone a few times it seems to happen on a every single one I have had. I've gone to 3 different verizon stores so its not that its one particular store. I'm going later to get another one and the rep at the store said she would give me $20 credit towards a blue tooth speaker if I wanted so I guess I'm gonna do that. I don't know if its just these speakers cant handle full volume on speaker phone?

noise cancellation problem ???

Hi there,
i have been noticing a very strange behavior in my phone these past two days...
my phone is on this firmware I9100XWKE7_CPWKD1_XXKE4 rooted with insecure kernel...
nothing fancy just regular apps
i noticed that when i call or some body called me the mic dosent work at all ...
he cant hear me
switching to speaker ... every thing is fine
rebooting --- no effect
connecting to the charger and then disconnecting the problem is gone -tested once-
Skype testing service ... the same problem the mic only work when in speaker phone
so after this i started thinking it is a software rather than firmware
any ideas ???
encountered the same problem with my gf's lg optimus 7. the mic was defective, there was a short circuit of some kind. had it replaced ( the mic) and everything worked good.
maybe there was some water or some sort of liquid that reached the internals.
nope no liquids ...
this is really annoying this is my 2nd phone the first one had a very loud noise on vibration
gonna do factory reset now
but it appears that when you scream really loud the phone will pick something probably from the noise canceling mic ...
i am out of uk now so going to samsung is not an option right now
so after a factory reset ... it appears that the mic is broken it dose pick very loud sounds though

Microphone help please!

My Microphone gets muted every now and then. I doesn't matter what Rom I'm using it does automatically. Talking on the phone people couldn't hear me. On sense when i would put the speaker on they could hear me fine. Once I reboot it works. I'm on CM7 anyone know why this happeneds?
Could be a hardware issue. If you're using speakerphone, then your voice goes through the microphone at the top of the phone in front of the headphone jack, in regular mode it goes through the bottom mic...not sure if this helps any...
Help is definitely needed
I also have this issue. Once I rooted my Thunderbolt is when the issue started. Just as described the microphone will randomly mute itself, but if the call is place on speakerphone the person on the phone can hear me. Also if I reboot the phone the issue seems to be temporarily resolved. Any suggestions on how to permanently fix this issue would be greatly appreciated. Thanks in advance.
Besides a factory reset, not much I can think of. If it still happens, get a replacement from verizon..

others cant hear me during call\Mic not turning on?

This issue has suddenly appeared. I have tried stock rom (nordic) CM9 and different aosp roms and also different modems, but the problem always returns after half a day or something.
So I can factory reset my phone, make a couple of calls and everythings fine for awhile but then suddenly no one can hear me during calls. I mean there is no sound at all, dont think the mic is turned on. The sound can start to get poor (like im on speaker and far away from the phone) til it doesnt work at all.
I have testet the microphones using voice recorder and taking a video and everything works fine, so i refuse to belive that the mic is faulty. Although its even weirder that the problem still persists after multiple full wipes (format system, cache, data, dalvik) different roms. Probably flashed stock rom with odin 3 times now and the problem is still there. I am now running fully stock non rooted, ive reset the custom binary counter and im ready to send the phone in for repair.
Unless the community can help me out ? any replies are appreciated!
Thanks!
Note that I can still hear the other person but he cant hear me. Switching to speaker and it all works fine ?!?!
What happends when i switch to speaker? does the phone switch microphones aswell? I understand that theres a mic on the top and bottom.

Yes. Regular voice calls use the lower mic, speakerphone uses the top mic. So it sounds like either something is blocking the lower mic, or the lower mic has failed. If you're comfortable opening the phone up yourself, you can try re-seating the rubber housing that is on the lower mic yourself. If not, take it to a service center.
Returned from repair
So guys I received med phone back from repair yesterday and the following parts have been replaced:
Module-RCV+MOT+MIC+E/Jack FPCB (GT_I9100)
ASSY ETC-SUB FPCB (GT_I9100)
And guess what, the problem still persists, my first phone call worked fine, but then the second call failed just like before?!?!!?
Is it possible that there is another hardware fault thats causing this?

Bump..... anyone???
Hmm. Maybe the rubber housing on the mic slipped after the first call, and is now blocking the mic. Or the part failed again. Or did you maybe put a case on the phone after the first call?

Galaxy S2- Microphone Goes Silent During call (hardware problem)

Microphone goes silent during call (hardware problem)
Hi guys, I had this problem for a long time, i want to make the story very short. My microphone becomes silent after 1 minute of use. I used the stock voice recorder to check it without the need to call someone. People get annoyed because they can't speak to me. Sometimes the microphone is silent from the very beginning of a conversation. I hear them well but they can't hear me. Once i've changed the mic flex cable/usb port plate and it looked like it worked fine for about a month. Then the problem came back. Could it be the motherboard? Did anyone experience something similar? I had to repair my camera right after buying it second hand. The technician told me the phone was in touch with water after he replaced the back camera.
bump. Just to add, weirdly my speakerphone doesn't work during calls, i don't hear people when its on, and my GPS is useless, it never finds any location. Could it be the motherboard? Pls i need your help.
