  3. I really like how much my ringer volume has actually increased.

    Just two qualms really;

    I didn’t really want to get rid of the camera sound.

    I also didn’t want to get rid of the touch sound (plays a sound when making a screen selection).

    Can anyone help me get these two features back without actually removing the increased speaker volume?

    I am new to Android so forgive me for being dumb.
    I downloaded the and installed it via ClockworkMod (CWM)

    If anyone can help me out, I will be very grateful to you 🙂

    Thank you in advance.

  4. Jayce,

    let me first express my gratitude for the helpfull info I’ve already received by reading many topics on your website; the explanations you give are very clear even for a beginner like me.

    Ok. Regarding the audio output of the Galaxy S3; I have a rooted GT-I9300 Int’l with stock kernel and JB. I tried all the options that are suggested by you and XDA Developer sites. I even tried to change the file myself with a text editor but to no avail; the file doesn’t permit any changes. For that matter; I can’t even delete it!!!
    I also copied the file to another directory, then changed permissions, edited the file to my liking and tried to copy back to the system/etc dir: nothing changed.
    I also did the flash, but got an abort message. I have BusyBox, Rom Toolbox and SuperSU installed, but none of them can help me. I’m desperate coz some of my older music files have quit a low output and almost not to listen to…
    Why can’t I overwrite the default_gain.conf file while others have it working?

    Hope you or anyone else who reads this can help me out?


  5. What I’ll do first is to use ES File Explorer. But I’m not sure what you mean by “grant SuperSU access”. Isn’t automatically done when you use a root explorer?

  6. Jayce,

    something strange is happening. When I open ES File Explorer SuperSu tells me “ES File Explorer has been granted la la la”. Meaning that it has root access etc. When I then go the settings, ES asks me to remember the “allow” access and when I enter yes, it takes a while and tells me “sorry test failed, this feature can not run on your phone”.
    Very strange, since I’m able to do just about everything with my phone.. For example, I have Omega Kitchen files and am able to install the boot animations, custom notification etc. You can’t do that with a non-rooted phone, can you?
    I tried for an update on SuperSu, but I have the latest version (0.99).
    Any suggestions?

  7. I followed your suggestion and checked root access with Root Checker and it gave me the result I already knew: I have root access!
    I’m also able to open the default_gain.conf file with the text editor built-in in Rom Toolbox Pro. But whe I try to open the file with the ES File Explorer editor, it comes up with the following error:

    Failed to open the file (

    Maybe this you a clue?

    ps When I open ES File Explorer I miss the usual confirmation from SuperSU: “application has been granted Superuser permissions for an interactive shell”

    It looks to me that SuperSU doesn’t recognize ES?

    Still hope that somebody can come up with a solution.


  8. Hi Jayce,

    I managed to edit the file! But not with ES. Instead I used AntTek explorer and that worked.

    Although now I have to say that I don’t notice any difference in volume…

  9. hi

    sorry i know this is old. but please help, my samsung galaxy s3 sch-s968c has no e default_gain.conf. what can i do?


  10. Hi, will the speaker of the Samsung Galaxy S3 be damaged when the volume is set to maximum (default) before the overwrite? What about after the overwrite, will that cause speaker of the S3 to shorten the life? Thanks
