Yes I did post this in the device specific forum, but no one seems to have any idea. But it has me very confused, So I thought I would bring it to the general community.
So I acquired a ET4G the other day from a friend who had dropped it in some water. He did an insurance claim so he has his new one and gave me this one to play with. Everything works fine except the mic and the notification light was stuck on.
I completely disassembled and cleaned the circuit board and contacts. Now the notification light works properly and the mic works when recording video.
There is no mic in skype, calls, searching, anything except video recording that I've tested so far.
Sooo, Does video recording use a separate mic , if not does anyone have any ideas?
It's running CM9 right now but shouldn't make a difference. I have already flashed it to stock and back to make sure it wasn't a software issue.
Any ideas would be appreciated

Hello XDA!
First, some background: A few weeks ago, my phone went for a swim. I let it dry for a few days and turned it back on, but the phone wasn't very reliable (time would run slow, half the time I couldn't make calls, and the 3G wouldn't work at all). The touchscreen however was perfectly fine. So I found an eBay auction where it seemed like everything worked except the touchscreen. I bought it, and transplanted my touchscreen onto it.
Unfortunately, while most things work, I don't have any audio coming out of the front speaker, meaning I can't hear people when I call them or they call me, and if I call them, I can't hear the ringing that goes on before the person picks up. I read on some forums this was potentially a software issue, so I reflashed the latest RUU, and got nothing. I flashed KaosFroyo v24 and still have nothing.
My current work around is to wear my headphones all the time with it (which isn't TOO inconvenient, since I listen to Pandora a lot). The microphone works. The speakerphone works (since it goes through the speaker in the back).
Does anyone know if it's possible to transplant that speaker as well? It seems unlikely since I'm pretty sure it is attached to the motherboard...
Thanks!
Hello guys,
My problem I am experiencing is with the microphone that picks up sound for videos and voice recording. In calls, it is fine, as the gs2 has 2 seperate microphones? One for calls and other for videos/voice recording.
Anyway, the problem started around 2 months back, it then disappeared after blowing into the microphone hole at the bottom. Now recently, it randomly began to not work again, so the same old static/screetching when recording was present, it even started to not record anything at all so I tried to vaccume it to get dust out, and it then started to record static and very distorted audio.
I left it a day, and WALLA! works, but now it has gone back to not recording any audio at all...
I'm not sure if this is hardware or software related?
Any light to be shed on my problem/suggestions would be really great, its still under warranty as well by the way.
Regards,
Carlos
It sounds like it may be damaged. I'd send it back for repair/replacement.
Incidentally, the SGS2 does have 2 microphones, but one of them is used for noise cancellation. It uses the same mic for both calls and recording. If it's 100% fine for every single call, but bad on video/audio recording then it may be that the recording level is a lot louder than the usual in-call level, and that's why you're getting different results.
Incidentally...

One of my biggest bug-bears!!!
http://tinyurl.com/3qcr7nd
I've recently noticed that I don't get sound when making a phone call unless I change to speakerphone. I don't make many calls so I don't know exactly how long it's been happening, but I first noticed it a couple weeks ago. I know that the other person can hear me fine when I'm on either setting. I've also switched ROMs, from Alien to the new CM7 beta, with no change.
Has this happened to anyone else? Is it most likely a hardware problem? I've never dropped my phone or anything, and it's only 3 months old. Does anyone know of an app that can test the normal phone speaker, because all other sounds have been working fine.
Thanks for any suggestions!

My guess is it's a hardware problem. I would have it checked out by your mobile phone company.
You can also look up "hardware test" in market and you will find apps there you can use to test your hardware. Sorry not to recommend one. There are many there if you look them up.
Sent from my Atrix XDA Premium App
Thanks for the response. I looked for an app already and didn't find anything useful. There were tests for just about everything else; touch screen, sensors, GPS, etc., and only two that I found that had an audio test at all. However, neither of them allowed me to specifically test the "phone" speaker.
I just think it's weird that all other sounds work fine. I'd really rather test it before I send it in to Motorola.
Thanks again!
This was a common issue on the Motorola Defy's. I had to send mine to Moto for repair. If you're within a year, AT&T will replace it.
I am having this exact same problem with homebase. but mine is intermittent it will work straight after a reboot
More sound issues
In my case I just updated from Froyo to Gingerbread, everything was working perfectly, when suddenly i stopped listening to the earpiece, the loudspeaker still works during calls,
On the other hand, if I try listening to music or any other sound, the loudspeakers dont work... any ideas of what could have caused the problem? It feels like some sort of driver issue, because while trying our the earpiece and loudspeaker during a call I was able to listen to one second of conversation through the earpiece...
i do have exactly the same issue...
putting pressure just beneath the fingerprint scanner, makes the earpiece work for an instant ...
its definitely a hardware issue...
m really fed up with dead spots on touchscreen n this earpiece issue....

Same problem here?
Does any1 have any fix..Help needed!!!
Hello XDA,
I recently purchased a new android phone off ebay (it's Motorola Razr xt912).
It turned out the front mic doesn't work at all. It doesn't matter wether I use stock android or my CM installation. It didn't stop working, it never worked since I got the phone.
First I noticed people couldn't hear me when I was making calls, so then I tested the mic with a recording application which allows to choose the source mic. While I was able to record sound using the rear mic without any problem (in the app and also using the camera app), I never could get any sound at all from the front mic, regardless of application or OS used. Therefore I think it can be concluded that it's a hardware issue.
I don't really know what to do about this, I could contact the seller on ebay, but unfortunatelly in the meantime I managed to scratch the back of the phone a bit (there is a small but clearly visible scratch on the back) so I'm not sure they'd be willing to replace my phone.
It occured to me that maybe I could somehow coerce the phone application to use the rear mic, is this possible? If so, how could it be done?
If not, what else would you advise me to do?
If need be, I suppose I could take the phone apart. I have succesfully repaired multiple pieces of electronics in past (multiple PSPs, ebook, etc...), however this phone is really tricky to open and work with and I'd really rather look for another solution prior to attempting to fix it myself on hardware level.
Any help is appreciated.

You clearly know that it is a hardware problem.
How can you expect the front mic to function using apps?
Use Voice Search and try to record through front mic.
There is an app which has an option to change the mic from where it must be recorded.
https://play.google.com/store/apps/details?id=yuku.mp3recorder.lite
I suggest you try to get the full version and moreover I never used that app before. So you are on your own.
If it still doesn't work, I suggest you to get that piece of hardware fixed in service centres rather than trying it out yourself.
I noticed this from the very beginning but it never actually bothered me that much to do anything about it. The Microphone has a very low Volume, for the Hotword Detection I actually have to put my Mouth in front of the screen to work. Also noticeably in Videos or Voice Recordings, or Skype Chats. I found this topic over at Reddit and seems like I'm not alone http://www.reddit.com/r/Nexus9/comments/2rgsnk/nexus_9_microphone_sensitivityvolume_very_low/
I wonder if anyone here has the same issue and if it is actually a Hardware or a Firmware Problem.
i just posted my thread before seeing yours... : http://forum.xda-developers.com/nexus-9/help/sound-low-videos-t3005703
same prob
Friend of mine who also owns the N9 is having this issue too. What Rom are you on, Stock or Custom?
