Fix For Low Microphone Volume On The Samsung Galaxy S II
by Hans Petter Eide
Since I received my Galaxy S II a month ago, people have been complaining that they can barely hear me in calls. I first found out that turning off the noise reduction (by pressing the menu button while in call, and then pressing “Noise Reduction Off”) partially solved the problem, but this naturally also meant that the noise reduction feature was gone.
So I started click around the menus on the phone trying to find a way to fix this. At last it seems that I have found a solution:
- In the phone dialer type in *#*#197328640#*#*
- A menu should now be shown. In the menu, press [5] AUDIO
- …then [1] NB (VOICE CALL)
- …then [1] HANDSET
- …then [1] VOLUME
- …then [1]SRC SPEECH RX Volume
- …then [5]5_lvl: 88 (note that you might have another value than 88 on your handset. Write down this value in case you want to revert to it later)
- The window that is now shown should have a line saying “Input?”. To input a new value press the menu button, then “Key Input”. Write 110 as the new value and press “OK“.
- You have now adjusted the microphone volume when noise reduction is disabled, and it is time to do the same when noise reduction is turned on.
- Press the menu button, and then “Back”. Do this four times in total, until you get back to the menu that the text “NB (Voice Call)” in the first row.
- Now, press [7] HANDSET(2MIC) and repeat steps 4 to 8 listed above.
I have had no complaints about the microphone volume after I completed these instructions. Hopefully it applies to you as well! The only downside with this trick is that it won’t survive a restart of the phone. A tip if you want to be unreachable without turning it off is by setting it in “Airplane Mode”. In this mode the phone barely consume any battery if it is not used.
Disclaimer: Although it is highly unlikely that it should happen, I take no responsibility if these steps should brick your device.

Thanks for this, should like to know how to make this permanent – but for now a nice workaround =)
I guess it is possible to make an application for rooted devices that alters the file used to set this setting. This application could be run on every startup, and one would at least have a simulated permanent solution :) I doubt that I’ll have time to look into this, but maybe someone else does?
I’ll hope this will be fixed in the future.
Seems to be working!
Thanks for this solution!
Seems to be working also for me!
Before “fix” it was 50/50 problem with low microphone.
Thanks :)
Just update my SGS2 to 2.3.4 at XDA. It’s seems like not solve yet. The mic volume is still too low.
Hi and thanks a lot for the trick! Do you know if there is a more permanent version?
I first found out that turning off the noise reduction (by pressing the menu button while in call, and then pressing “Noise Reduction Off”)
I dont get this option of noice reduction while pressing menu button during call why ???
mine is out of the box Gs2
Wills: Yes, unfortunately that seems to be true.
Ced: Over the weekend I will look into if it is possible to develop an application that edits the value when the device boots. It will require at least root access, and most likely BusyBox.
Lalit: Have you upgraded your firmware lately? Connect the phone to your computer, and open the Kies application. You should then see a notification that a new firmware is available for download.

On a regular basis check the pc’s entire method. I enjoy to perform scans overnight because they decelerate your personal computer and could acquire a short time. Only when section of your pc program seems to be attacked, it is possible to scan the particular believe element only. In case you are by using a free of charge program, make certain it eliminates the particular viruses it’s discovered. A few of these free plans will recognize the actual dangers however need choose the program in order because of it to eliminate the problem. I think these particular applications should be removed and also exchanged by packages who have full performance.
