[T-Mobile LG G2x] iunlock:
Perhaps you're referring to the Samsung Galaxy S II? If so, I'm right on point with you...

I'm going to pick up the Sensation today...G2X is nice, but it gets boring fast...HTC has always made good hardware. Looks good too...The new interface looks promising as well...way cooler than the bare bone G2X...yea yea root it add custom roms blah blah blah...still that doesn't take away from the fact that the G2X is grandpa in design compared to the new HTC S4G. Let alone the SCREEN....Period.

Selling the G2X while I can to get a decent chunk of change on it. Going to take advantage of it not being available on TM's website. Right now would be the best time to sell..

The way I see it...facts that is...the Galaxy S II, if it ever arrives to TM, will be the ultimate phone hands down...in the mean time the HTC Sensation 4g is the throne holder...G2X isn't too far behind, but overall the HTC S4G is the next best thing...

Samsung Galaxy S II...hurry up!
[Galaxy S II General] hpe:
So, it seems I have finally found out how to adjust the microphone volume on the phone.

I have posted the instructions on my blog. If you try the solution it please respond if it works or not.
[Galaxy S II General] eitama:
This might be veey interesting. I changed 88 to 100 but will only be able to talk to someone tomorrow.

From personal experience both sgs ans sgs2 have low treble input sent to peer. Ots annoying.

Posted from Galaxy S II
[Galaxy S II General] Limpperi:
tried, we will see...
[Galaxy S II General] cmd512:
Interesting, there's an option for speaker receive volume too...
[Galaxy S II General] kei_kusanagi:
I tried it but it didn't work on audio recording (Hi-Q MP3 Recorder).

There is some way to adjust mic volume of voice recording?, My old SGS recordings were a lot louder than on my new SGSII.
[Galaxy S II General] @Class:
Great thank you so much for the post. It helped me out.
[Galaxy S II General] kreoXDA:
MY SGS2 DOES NOT HAVE THIS VOLUME ISSUE! PEOPLE HEAR ME VERY WELL, SOMETIMES THEY ACTUALLY LOWER THE VOLUME IT IS SO LOUD!!!

:)

Seriously, how much better does it get? I am not in a noise free environment at the moment, how big of a gain does this produce? Does this fix work with the genuine wired headphones?
[Galaxy S II General] connectandroid:
i thought this fix was temporary only, after a phone reboot the fix resets to default ?
[Galaxy S II General] ph00ny:
how often do you reboot your phone?
[Galaxy S II General] iznee:
I must admit...in all the smartphone that i have ever used.....This is the only phone that i have never rebooted except when flashing roms/kernels etc... :D
[Galaxy S II General] zkyevolved:
I never reboot! I did today, because I wanted to calibrate the battery for the first time and I let it die. So I let it die after 24 hours of use, and then when it turned on it rebooted :)

I love my phone :D
[Galaxy S II General] marvi0:
It works but sadly as others have already mentioned, after a reboot, you have to re enter the settings, which is the only draw back, and am one of those who reboots the phone on a daily. Is there any way of making this permanent even following a reboot?. I can imagine its probably difficult, but thought I'd ask anywhere. Thanks op.
[Galaxy S II General] eitama:
I'm actually looking for a way to lower the input gain, as my voice comes out distorted on the other side. Any clues? Besides the obvious "Turn 88 into something lower, I tried 70 and didn't work"
[Galaxy S II General] hpe:
I don't know how the values can be saved so that they survive a restart. Personally I only restart my phone when it runs out of battery, or if I've done flashing that requries a reboot. If I need to disconnect from the real world airplane mode is used.

So, has anyone had any luck using this method? Seems to work for me.

That's quite the opposite problem :) Other than what you tried I have no idea. Sounds like a faulty device?
[Galaxy S II General] eitama:
Actually, I tried 20 yesterday, and it did solve my problem!

Now sound is crisp and undistorted!

The question is,

1. How to make it stick reboot.

2. What do the rest of the volumes do? Vol0_1 0_2 0_3 etc, you suggested to edit number 5. Why specifically that one?
[Galaxy S II General] hpe:
1. Still a mystery :)

2. My guess is that there are certain levels of output, and that all of them should be adjusted according to the other to have a linear line. The fact that I wrote that only 5 should be edited was simply because that worked for me.
[Galaxy S II General] arix:
First, great thanks hpe !!

I got my phone 2 days ago and got same problem.

ppl could not hear me well.

I tried your solution, hope it will help (tried 1-2 calls and seems ok).

I have noticed also that when you talk you should be

stable with your hand and your face , I mean,

it should be with fix distance between the mouth and phone, not important the distance but it should be stable during the call, if not the AGC comes up and down and the other side can't hear you well...

About save setting,

Maybe there is ini file or something (rooted phone) that can be changed to keep value after reboot, I have noticed in the 2 days I have the phone that I had to reboot phone after install application to get it works well.
[Galaxy S II General] massimilianonball:
I've follow the hpe solution but i still have volume problem :(

My specific problem is:

On Normal Mic call > very low volume... on my SGS2 with android 2.3.3

But with Speaker call > clear (no problem)

Very strange!! I can't be able to solve this problem.

I'd like to precise that with other voip app like bria or "csip simple" i have no problem, mic volume is perfect..

:mad:
[Galaxy S II General] XpLoDWilD:
Speaker call uses different mic settings (since you've a higher distance between your mouth and the mic while using speaker), so it might just the "normal mic call" volume setting which fails.
[Galaxy S II General] massimilianonball:
I have understand and many thanks for your reply but it's strange that those settings works perfectly with the other voip applications.. :rolleyes:
[Galaxy S II General] XpLoDWilD:
You should try with microphone recorder and such, or even a different dialer app. Maybe that's just the official dialer who is having this issue (using a config file for this sort of things, I never really studied Phone.apk).
[Galaxy S II General] massimilianonball:
I see.. We will wait for cm7 for the sgs 2..

I hope that with that rom this problem will solved..
[Galaxy S II General] arix:
I m not sure 100% yet, but I have noticed that without the silicone case the mic is much better...

Meanwhile I made big holes in the silicone case...

Please try it and let us know...
[Galaxy S II General] massimilianonball:
Thanks forse your reply, but i don't use any kind of silicon protection..

Can i make a big hole on the telephone just around the mic...??? :):)
[Galaxy S II General] tristanmaiolo:
I tried following the instructions on the blog but when i typed in the numbers no menu came up. Is there a difference between aussie versions of the sg2? i know they dont have the nfc chip in them but i wouldnt think the menu options would be any different. Please help cos this is annoying as hell.
[Galaxy S II General] tristanmaiolo:
ok so i managed to get it to work with a few more star and hashes at the end but wen i hit 5 it says caution menu being blocked what now?
[Galaxy S II General] amitambika:
I am getting the same message
[Galaxy S II General] tristanmaiolo:
Just enter in [1] (Voice Calls) and it will let you access themenu I did it all but it didnt fix the problem. I took the phone in to one shop who insisted nothing was wrong with it even after trying it after some harsh words I went to another store and they checked it saw that there was a problem and switched phones and we tried the new one which worked fine. i am guessing a bad batch of phones have been released. They told me it was strange because they haven't had any issues so I am asking people with the same issue to go in and get the phone changed as I don't think Samsung is aware of the problem and as for the first shop they are going to cop a complaint from me over my treatment. They basically said I was lying and that they could change it but they won't! Assholes!!
[Galaxy S II General] benny31:
any reason why that code does not work on my handset other codes do but not that!!!! ???
[Galaxy S II General] amitambika:
Ok the solution to this is that when you get caution message.go to menu button.you will get option of input values.press that and enter anything like 1 or 2.After that you can go further inside the menu.
[Galaxy S II General] dreamer_es:
Hello guys!

I'm having more or less the same problem here but it doesn't get any better bumping up the volume values you talk about. Also the Recorder app and voice search don't get any sound except slightly when I really shout at the microphone hole.

Any ideas of what to do??
[Galaxy S II General] massimilianonball:
I've tried many different voip application and i've see that with sipdroid you can increase the Mic boost.. I've choose an 80% Mic boost and with that configuration the audio in conversation is quite perfect.. So for me there isn't an hardware problem the only solution should be an application or a patch that increase the Mic boost. I hope that someone of the xda developers will make this patch for solve this boring problem :-)
[Galaxy S II General] MarkSkov:
I did have a bit of trouble with low mic volume and got a new phone from my supplier for a separate reason and now it seems to be much better. Was a bit of a problem for me at first because I tend to mumble ;)
[Galaxy S II General] _mex_:
I had the same issues while using some voip clients and finally i found the reason why :)

After spending a lot time on this issue i noticed, that the S II has TWO MICROPHONES. Yes, the phone has one microphone on the top, right to the headphone plug and one on the bottom, right to the usb plug.

Most voip clients are using by default the wrong upper microphone. So raising the microphone gain is just a workaround for this issue.

I did not found a solution yet how to tell the phone to use the other mic.

Just another simple work around is to hold the phone during the phone call turned around in your hand
[Galaxy S II General] _mex_:
I found only one sip client, where i can switch which microphone should be used: csipsimple

After installing, press the settings key -> Settings. Press the settings key again and choose "Expert mode". Now go to Media -> Microphone source and select either "DEFAULT" or "MIC". Seems that this setting depends on the rom you are using.
[Galaxy S II General] EarlZ:
Since the setting change involved is tagged as "Rx" it means receive ( if im not mistaken ) so your bumping the volume that your getting, I think "Tx" should be the ones changed.
[Galaxy S II General] massimilianonball:
So the situation it's a little bit strange because of all those differences between our sgs2 and the other android phones.. I've try the built in sip client and the problem is always the same :-(:-(

So we have to wait for a complete solution from Samsung (about the Mic boost) and from all the developers of voip application (for a customization of the menu of their application for our sgs2).
[Galaxy S II General] holyguyz:
Hi guyz,

I have 2 SGS2 phone with exactly the same firmware. Basically, my wife's SGS2 have a very clear mic volume compare with mine (tested calling each other). My SGS2 having same low mic volume problem (during calls). Beside that, I did try whatever options (i.e. flash to 2.3.4 (tried several roms), Volume+, Volume Hack, phone dialer *#*#197328640#*#*, etc) which still seems not work for me.

Currently, I have sent my SGS2 to service centre to have a check. Hopefully they can fix the problem. I think, high chances could be the hardware problem (could be due to voice cancellation technology).

P.S. Now I have to swap back to my previous old and slow phone while waiting for my SGS2 to be fixed in 2-3 weeks time or more. :mad: Btw, my old phone have much more clear mic than SGS2.
[Galaxy S II General] massimilianonball:
Do you have some (warranty) problem with the service center because of the different (i think unofficial..) Rom that you have flash..??
[Galaxy S II General] holyguyz:
This is my 2nd time sent it for service (retailer service center, not from Samsung), which the problem was not fixed at the 1st time. They have flashed the phone before, i think there shouldn't be any problem with the warranty. Perhaps you might not want to take a risk, you can always reset Binary count with usb jig. Browse around, you should be able to find it.
[Galaxy S II General] massimilianonball:
Yes i should buy a jig.. And i think that i will go to a Samsung service center too.. I'd like to listen their. opinion.
[Galaxy S II General] marvi0:
ok i remeber previously, i was able to enter that code, to change the volume sound, but now when i enter the code, nothing is showing up the screen, am using cyanogemmod, please?
[Galaxy S II General] drreality:
mate, these codes r made by sammy stock roms only!

cm7 is vanilla android with some modifications, so it wont work ;)
[Galaxy S II General] holyguyz:
Hey guyz, finally my SGS2 is back to ROCK!

I just got my 5th replacement unit, because they can't fix the low mic volume problem and the camera mechanism noise. It's defective and nothing can be done.

Now my SGS2 has a very clear mic volume during calls. No more shouting, screaming and complaining. :D Save my voice for longer quality business call.
[Galaxy S II General] euphoria47:
This is the truth. Like one other person in he thread, I had issue with too much microphone gain on the wired headset. Since the gain option had a string value, I adjusted the RX value; at first I put it at 60, but then I decided to remove all of the tape I put over the mic hole on my headset, so it was too loud again. I changed the value to 45 and all was fine again.

My mic volume was so loud that even people with their phone volume at the lowest setting couldn't be on the phone with me, unless I was literally whispering and holding the mic away from my mouth.

Haven't reset my phone since, but assume the setting will be lost when I reboot.
[Galaxy S II General] massimilianonball:
I'm happy to report that with the last version of Leomar75 rom (2.6), the low Mic problem is completely solved...!! I don't know why but now my voice is strong and clear. I'm so happy!! Finally this problem is REALLY solved..!! I must investigate with Leo for know why..

I'll write you what i will found.. :-):-)
[Galaxy S II General] equinox1979:
It would be great if anyone else could confirm that!!

Thanks
[Galaxy S II General] massimilianonball:
Yes.. I'm waiting for a Leo's answer but at the moment he is so busy..

Any one else have tried Leo's Rom in this discussion..??
[Galaxy S II General] henny.van.beers:
All,

I've adjusted the microphone setting according the procedure described by hpe.

I now experience that the speaker is much louder, so I suppose that we should not look for the "RX"-options, but for the "TX"option in the menu.

Also I saw an option called "Diamond Solution".

Does anyone know what this is for and how it could help fix the problem ??
[Galaxy S II General] ronnbon:
Would really like to know that too... :confused:
[Galaxy S II General] blueseeker:
My problem with the low microphone volume is due the "noise cancellation" feature that for an IDIOTIC reason is ON by default which instead should be OFF!!!

Everytime I start a new conversation I must disable the frickin' option. I rooted my phone just because of this, I don't want a new ROM, I just want a phone.apk with this option switched off. I didn't find one that actually worked on my KE7. Still searching ...
[Galaxy S II General] arix:
You can find it here:

http://xdaforums.com/showthread.php?t=1251922&page=2
[Galaxy S II General] holyguyz:
Yes, exactly. I was also facing the same problem before. I tried varies options i.e rooting, flashing custom ROMs (DarkyROM, Litening, VillainROM & etc), different kernels and plenty mic volume boost apps, but still won't work for me.

Noise cancellation is a mobile technology built-in to reduce the unpleasantly background loud sounds during calls. I have 2 units of SGS2 with same preloaded Samsung official ROM. One with no problem at all, but the other one with mic volume problem (my previous SGS2).

Now after I replaced to 5th new unit, it back to normal working condition. No need to enable/disable the noice cancellation button on every calls.
[Galaxy S II General] EightM:
I have a new i777 At&t Galaxy S 2.

I seem to be stumped using the original instructions in the OP's blog. Once I get to the developer option menu, and hit [5] Audio. It doesn't take me to the next sub-menu. I just return back to the same main menu that I was at previously.

All of the other options lead to their respective sub-menu's. It seems to only be the [5] Audio menu that is disabled or broken.

Can anyone help with this? Any ideas on other ways to access these settings?
[Galaxy S II General] nraudigy2:
Mine is at 100% already with 2.3.5. 110 might help little.

I folow this steps but no fix for me,,,poeple say "still mumbling"..

KI3 Firmware Fixes ALL Audio issues if anyone who has the infamous volume issue. Makes your handset,headset, speaker LOUD, that's the way it should of been from the beginning for us how suffered from the volume issue.

Update to KI3 Now.
[Galaxy S II General] lvca:
Fixed!!!

I had the same problem most of you described here. At first no mic volume at all, and after that I had to shout in order for other party to hear me at all. I had tried all the "smart" solution I could find, another ROM, kernel, secret codes, service manual, etc. None of it had worked. And at the end the "stupid" solution worked. I cleand lower mic with pressured air and now I can normally talk over the phone.
[Galaxy S II General] dzontra11:
You cleaned what????More details please?
[Galaxy S II General] lvca:
Just blew the compressed air right through that little hole right next to usb slot where is supposed to be that lower microphone.
[Galaxy S II General] henny.van.beers:
Hi, seems I am a newbee to upgrading my Galaxy S2.

Where can I find KI3 software ?

Can I install it "on top of" my current KI2 version without bricking my phone ?

Will the language still be Dutch ??
[Galaxy S II General] madmaximillian:
Nope no solution found yet. This problem still exists. Completely ridiculous.

Even worse is how amazing this phone is made out to be, yet such a critical and gamebreaking problem like this exists and is wholly unsolveable. How do you people recommend this phone when it's got such an important flaw?
[Galaxy S II General] dzontra11:
Man just read posts.I solve this problem....you need air....:-)
[Galaxy S II General] dzontra11:
In fact yiu need something like this..trust me.
[Galaxy S II General] madmaximillian:
The update hasn't worked for me in regards to the actual "infamous volume issue" - which is low headset volume during calls and media, etc.

People are still reporting this problem exists. I've just received this phone and may have to just ebay it since it's unusable with this problem.
[Galaxy S II General] henny.van.beers:
Yep, I installed the latest release on my SGS II (Gingerbread 2.3.5).

Nothing has changed; the mic is still not working properly.:(

Suppose that I will have to go out and buy a bottle of compressed air.

Any other ideas ???

(oh by the way - I have to change my signature ....)
[Galaxy S II General] holyguyz:
it is more referring to hardware problems. I did try numerious ways (i.e. update to latest official firmware/custom rom, change setting at samsung phone menu, volume hack, disable noise cancellation, etc) to solve the mic problem, unfortunately they won't help.

there's few options:

1. replace microphone module.

2. remove microphone rubber.

3. replace another SGS2 phone (since it's still under warranty).

Mine, replaced to another new unit did solve my problem.
[Galaxy S II General] sxi200:
Wow....what timing! This is the first time I've heard someone mention removing the microphone rubber, which is exactly what I just finished doing.

Here's why I did it. I've had some complaints about my voice sounding muffled at times.

So I had a look into the bottom microphone hole and noticed what looked like something white under it. I thought it might be some dirt so I used a pin to try and remove it but couldn't. Also, when I was putting the pin in it, it only went as far as this white thing. So I pulled the phone apart to see what it was.

It turned out what I could see was the microphone rubber housing. I thought then that the housing is actually blocking the hole which could be the reason I sound muffled.

It looked as if the rubber housing still needed to go down a little so the 2 holes met correctly but every time I pushed it down it came up again.

It pissed me off so I decided to lift it up and remove it completely from the microphone.

I haven't had the chance to test it yet as it early in the morning here, but will post later about how it went/sounds.
[Galaxy S II General] hananakajima:
hi

please i need help with the voice reduction it is always disabled when i have a phone call can u help me?
[Galaxy S II General] dzontra11:
I just use new Sgs2 and problem solved..now i can see mic hole its totaly diferent then on the older g2.....
[Galaxy S II General] holyguyz:
so, how is it? did you manage to solve it by removing the microphone rubber?
[Galaxy S II General] sxi200:
Well I made a couple of calls. Still had complaints about echo which was solved by removing the rubber case and turning noise reduction off on another occasion with the case still on.

Haven't asked about clarity but the person on the other end didn't complain about quality.

I'm catching up with friends later and will swap phones to hear how my phone sounds to the other person. Unfortunately I don't know what I'm comparing it to as I didn't test before I removed the rubber.

Will post further results later tonight.
[Galaxy S II General] holyguyz:
If problem still exist, by any chance since there's still under warranty, just replace it. I was also experience the same problem. Finally I decided to send it back for replacement to another new unit.

Good luck!

Btw, i sent it twice for repair (eventhou still under warranty) and twice the problem was not solved. The third time, they just replaced me a new unit. They said they can't fix the problem and no further explanation.
[Galaxy S II General] Coedy:
Phone your own number and you should be able to leave yourself a voicemail ;), that's how I test mine.

Could you make a step by step of how you did the mic mod? (how to get at it etc)
[Galaxy S II General] sxi200:
Well I can't send it back under warranty as I bought it second hand and don't have the original invoice.

If its not purchased from an authorised reseller Samsung will not help you. A friend tried to do that with an S1 but Samsung were not willing to help, even though he bought it brand new in the box.

Anyway, called my phone using a friends phone and voice came through loud and clear. Hopefully that's fixed it but time will tell.
