Have you tried another ROM, restore backup etc. In short, what measures have you taken on your own to troubleshoot this problem.
- yes, the phone uses another means/ Mic when you are using loud speaker

I've had this problem since about 2 months after i received the phone, I posted the question here last year but no one knew. hopefully you can get a answer!!! I'm just so used to using my phone on loud speaker now every time somebody calls haha.

Unfortunatly i was out of the country when it happened so i was never able to claim warranty on the phone or anything so i've had to live with it.
I have tried everything i can think of to try and fix it. Different ROMS, diferent kernals, different modems. nothing has fixed it.
One thing to note, is that when i have headphones in, the mic is fine. Would the be some trickery i could pull to make the phone always use the loudspeaker microphone, even when in handset mode.
current rom is paranoid android 1.99 w/ dorimanx kernal.

i think that lower mic is used when speaker is off , but in speaker phone it uses the the upper mic.

Sorry about that.
Your own case looks like a definite hardware issue. Too bad you are out of country but if you can still visit any Samsung service center, you might be lucky. Those guys are always very nice and helpful to customers in my country even if you are out of warranty.

I've not flashed a newer ROM to see if is that yet as its my wife's phone and I've not had time to back it up before I flash.
I have the same phone and not had this problem
I've also posted in the neat ROM thread and no one has had the same issue
So if there is two mics do you think it could be broken

Since its your woman's phone and you can't probably flash a new ROM at this moment, fine.
I'll say, let's assume it's as hardware issue.
I'll advise flash back your stock original or officially update firmware, And just send it to service center for repairs like normal warranty claim.
Good luck

Serious microfone problem

Hi all
Am I the only one experiencing microfone problems on my new galaxy S3?? Im on my third I9300, because of this issue...
People complaining about that the mic vol goes up and down...
I'm also facing similar issues. I'm going to get mine replaced also.
First of all guys make sure 100% it's not the mic. Record some song and see if you still have the problem. I was facing similar issues with the mic going up and down durring calls.
In my case it was the simcard. Don't ask me why, because the same simcard was working fine in another phone, but after getting a replacement everybody said that they can hear me a whole lot better.

I am going through the very same issues.
I had a mic problem with my first S3 during phone calls. It was really annoying me because I couldn't do anything about it everyone was saying they couldn't hear me etc.
The sim I am using is an British UK O2 micro simcard that I used in a iphone 4, cheap samsung, and samsung S2 previously with no problems at all.
I then returned the phone to the T-mobile shop retailers, they said it was rare and not a common fault.
My new one is doing the exact same thing, I didn't update it nor is there a new update.
Can someone please help. Thank you.
I am getting the same issue but not everytime. I am sure that it is not the fault in mic that is causing this problem, as i recorded my voice (using both mics, the one at the top and at the bottom) and it was crytal clear.
turn off Noise Cancelling... fixed my problems
same problem
Had the same issue ,also with the s 2 , but the trick then (witch also worked now ) was to turn off the noise cancellation .
During a call just take the phone away from your ear and under the callers picture there u will find the option to do so
I have literally just started having the same issue today.
Am on FoxHound Rom 1.4 with Siyah Kernel. Had no problems, even made calls last night, perfect.
Then I tried switching Fast Dormancy on, flashed stock kernel and this morning I find when I made calls to Orange customer services, they were saying they couldn't hear me.
Tried testing it myself, and no matter who I call no-one can hear me.
I've tried:
re-flashing rom, kernel
Tried latest stock roms such as I9300XXBLG8_I9300OXABLG8_I9300XXLG8_HOME.tar.md5, none have made a difference. Even Roms I had backed up in clockworkmod that were working perfectly, like CM10 preview and CM9 have stopped working.
I've tried disabling Noise reduction, which has had no effect. Tried factory reset, flashing modems, kernels, roms, stock roms, nothing has made a difference. I can record video, google talk, anything else fine, just not get anything from the mic when making phone calls.
Tried putting a friends 3 SIM in, and the same thing, so it's definitely not network related either. I definately hope it isn't a hardware fault, as I bought mine on ebay and it isn't insured. Was kinda hoping for more than 2 mores usage out of a phone :crying:

! HELP ! Audio (Headset) output problem

Hi all , since yesterday I noticed on my i9100 a very strange problem with my audio output. Let me describe the problem: When I plug the original headset from the S2 box , I hear the sound is like under water and when i plug in a normal earphones without a microphone (with two rings only) there is no sound. I dont know what should I do , I mean , I tried to flash some other firmware like the Sammy XWLPG but nothing changed. Btw I am running the latest CM9 nightlies with latest Siyah kernel and i never noticed such a problem before. After all I think its a hardware problem but the phone is branded to T-mobile and it would take 1 month i think when it comes back from the Samsung service center. Thank you for answers.
Just give your phone to SSC, not T-Mobile. It will be faster.

[CM9 RC2] Mic not working whilst on speakerphone

Hi XDAers,
I believe since rooting (it might have occurred some time after) my Samsung Galaxy SII GT9100, I am not able to use my speakerphone as the other party to the call can't hear me. This problem is the same whether I use the regular phone, Skype, Viber or any other communication program. I have no problems with the mic when the phone is not on speakerphone, and I can use any recording application successfully.
I originally rooted my phone, flashed LighteningROM, went back to my service providers ROM (though rooted), and just today switched to CM9. I'm not sure exactly when the problem started occurring, but it was AFTER flashing to LighteningROM and before flashing to CM9. Is there any way to debug the error? Could it be due to flashing a bad radio or the like?
Any help would be greatly appreciated.
Speakerphone uses the top mic, not the bottom. Is the top mic clear and uncovered that you can see? If so, it may either be a hardware issue with the upper mic, or the rubber housing on the upper mic in the internals of the phone may not be seated properly, and is blocking sound to it.

The top mic seems to be uncovered. I believe I once read that Sound Recorder and applications alike use the top mic as well? If this is the case, why is the mic working in these applications?

Wasn't my intention to "get you" - hope you didn't take it the wrong way! I've just flashed back to stock ROM, but the problem persists. It appears people CAN hear me, however I am so low, they say it's worse than if I whisper with speakerphone off. Looks like it has to go back?

When I said "you got me", it's another way of saying "I don't know". I took no offense.
And yup, if you don't wanna mess with opening up the phone yourself, and you still have warranty, I'd flash back to stock, reset the flash counter, and send it in.

Did you ever get this working with your S2? I'm having the exact same problem. I flashed the stock 4.1.2 Jellybean via Odin and my stats are as follows:
Kernel: 3.0.31-Siyah-s2-v6.0b5+
ROM: I9100XWLSW
ROM Codename: REL
Radio Version: I9100XXMS2
Should I try flashing a different stock ROM? Does each one bring a different radio that may make a difference? Thanks.

Cannot be heard over internal mic

A weird thing happened to me:
After installing CM11,no one can here me over the internal mic,and I can only be heard when I use the speaker.
Sometimes,I can be heard very low,sometimes regularly,and sometimes not at all.
All other mics and speakers work just fine,as I can hear everything,from music to videos,but face the exact same problem when recording audio(when on heavy metal vocal lessons ),and when trying to send a voice message over What's App.
Have tried flashing older Jelly Bean roms,using Odin,and have temporarily been able to solve the problem,only finding out the problem persists after a random number of days,differs from rom to rom.
Have been to 3 labs here in Israel,and every time the claim is that the phone is fine,or that it's not a mic problem,but an audio chip one,which is pretty expensive to solve.(not that I mind spending on it,as buying a new decent phone here is double to three times the repair)
The thing is,every time I flash a new rom,a new modem,add a DSP manager,the phone is just fine,at least for a couple of hours,to a few days.
Been thinking it's a software,rather than a hardware issue,so am here to consult with you.
Should I:
1.Flash a stock rom again,but try one that's been altered for the Israeli user?
2.Flash CM12 Beta,in hopes a lollipop would keep fix it....
BTW:
Is flashing with Odin like wiping the system and data partitions?
I've been using numerous roms over the years,from ICS to Kitkat.
Never ever have I faced such a weird problem......
Thanks in advance and best regards,
Yohai.
I'm also having the same issue....
Some others also have the same issue...See the link below:
http://forum.xda-developers.com/galaxy-s2/help/confused-t2777776
I did forum search...Many seems to have this issue...And the problem is still un solved
I also checked if its hardware...But the phone repair guy is saying everything is fine with the mic...
Someone needs to seriously check this problem...
Currently on NEAT ROM v6.4 (4.1.2)...Few hours of usage, the mic is still working...

I don't know a stock rom that has been modified by an israeli user. You should try flashing neatrom lite first by Sale. CM12 beta won't improve anything (although it might). Most problems regarding to phone calls are to do with flashing 4.4.4 roms, most of them are caused by not flashing roms properly. Reverting to older version of android will (most of the time) solve your problem.

Did the issue happen with stock samsung rom? If no, you might have to use that.
SOLUTION!!!
Today,I went to a lab,which came out to be not the cheapest,but the most professional:
Seams out,the problem was with the mic itself,and the best solution was to replace the entire charging flat.(the mic is just a part of it,and in order to avoid future problems,it is best advised to replace the flat itself,not just the soldered mic)
After going to eat and returning an hour later-problem solved!
This just shows you,how some "professional" labs are hiring retarded technicians.
All you have to do is listen,and think SIMPLE!!!
Cheers and thanks for answering!!
In hope of contributing something to XDA's community,
Yohai.

One query
Charging flat means - the board containing the mic, charging socket etc..?
And what's the price for that?

Flat=Board,yeah.
Here,we call it a "flat",I guess 'cause it's a flat board.....
The price?150 NIS,others charge about 90-129 NIS.
How much is it in $?
150 NIS= about 42$
I'm beginning a course,next week,which will qualify me as a Mobile Technician.
Sadly,I couldn't replace the flat myself,as I have no knowledge on how to do it,but if I knew,the board itself would have cost me about 30 NIS+VAT.
See the big difference?
Knowledge=Money,my friend.
Peace!

[Poll] Starting to hate the G2

Okay guys, this entire month I have been considering getting rid of my G2. Will try to keep the story short.
About 4 months ago, I sent my G2 (D802) to repair center. Issue was: at times, people could not hear me during calls. They ended up giving me a completely new G2 few months ago. This week alone, I have experienced at least 5 times where people could not hear me. Only workaround when this happens is to turn on speakers (however, everyone next to you will hear the conversation which it is not exactly great).
Getting sick of it. Calls. I repeat, CALLS I can not even make properly with this phone. Everytime I pick up the phone/call someone, I have to wonder if they will be able to hear me.
Currently I am on completely stock unrooted 20H KitKat, I have tried lollipop firmware but the issue remains. Happened on KitKat 20D too. There's a chance the issue is not on Jelly Bean but I have not tested that because I don't really want to be on JB.
I assume I am not the only one on this boat seeing as the issue is reported by a lot. Share thoughts, possible solutions, etc.
@eepyikes @vPro97 join the discussion.
What kind of cover do you use?
_____________________________________Read more write less and be smart
Are you covering your mic with your finger maybe?It happens easily on g2.
No cover is being used. Pretty darn sure I am not holding anything over the mic. But I'll pay more attention to that from now on.
Look at how many people have reported this issue...

I have the same 'hate' to the gps of this phone but..this phone is great all is working great and fast after 1y and 4m..only the gps is super weak.
had you think that maybe your signal/phone provider is to blame? if signal is weak you should try another sim card or another place

Nah. Changed provider about two months ago. Same same.
I have an issue when people are not able to hear me, and it always happens if i want my hands to be free and phone is held between my ears and shoulders(Maybe some issue with noise cancelling or misaligned microphone). Otherwise it just works fine.
This may help you....
If you have turn on "Ok Google "detection from any screen!
I have faced similar problems...I thought that was hardware issue but When I turn off that feature My G2 was back on form and now they can hear me properly
Or another way to get rid away of this **** is to try custom rom also......
i have that problem with ANY stock or stock-based rom..... which is why i got fed up and installed CM12 permanently...... the "ok google" detection thing didn't work for me.... i tried taping the top mic but then i ran into random issues where the mic fails if loudspeaker is on.... no such problems with CM...

I asked in one thread if CM/AOSP ROMs had the same issue. Never got the answer until now. Thank you. This is probably the only solution.
Personally, I usually prefer stock based ROMs but that is about to change.
Note: disabling "ok Google" to fix it is only a myth. It does not help. Tried that and so did many others.
Sent from my LG-D802
and to be honest because of this i hope CM doesn't get the 2nd mic working. lol
It's the Google now detection, open Google now, goto settings and turn off From any screen
Maybe there is some dust or some other stuff in the small holes where the mic is which is making your voice more quiet or almost completely mutes the sound you are trying to record.
You should try and DISABLE Voice enhancement at Settings>Networks>Call..
it helped my whatsapp voice messages to be played clearly
Have had 5 G2s for different reasons and never ran into a Mic problem.
Have even used various Roms from stock JB to KK to Optimus G3.
Am on Tmobile and used nothing but D801s.
All have been white.
Not sure if that helps
There's hope for you if you're able to sell and replace your phone with another used G2 in mint condition
My experience is, once you've done a repair and things look botched, change the phone.
Sent from my SM-N910H using XDA Premium HD app
Have you tried increasing the volume of the mic by editing the mixer_paths.xml.
Sent from my LG-D802 using XDA Free mobile app
I had the same problem after i've bought my G2 last year. Even asked in offical german LG forum but got no answer.
Solution for me was flashing custom kernel (dorimanx). Since that time i've alway been on custom rom (stock and aosp) and never had that problem again.
Wich rev do you have?
