Do you feel that the volume output of your Galaxy S4 is not loud enough? If yes, today we got an effective workaround for you. The problem of low volume is universal to most Samsung Galaxy devices. If you are at a calm place, low ringtone volume is not a problem at all but when you are out in a market or a crowded or noisy place and you are unable to hear the notification sounds, it does create problems.

We certainly do not want irritatingly loud volume but it should at least be audible enough so that we do not miss a call or attend to an incoming notification. Earlier, we shared a trick on how to boost volume on some older Galaxy device like S3 and Note 2. The method works on the Galaxy S4 too but the volume gain configuration is a little different.

If you browse the system/etc directory on your device, you will find 2 files, namely “default_gain.conf” and “Volume.db”. These files contain the configuration of volume intensity values that determine how loud the sound output of your device will be. By editing those values using appropriate method, you can significantly increase or decrease the speaker volume of your Samsung Galaxy S4.

Since the procedure given below involves modifying system files on your Galaxy S4, it is just imperative that you have root access on your device. If you have yet rooted your Galaxy S4, we have rooting tutorials for almost all variants of the device.

How to Root Samsung Galaxy S4 (All Models)

Tips and Tricks for Galaxy S4 Users


Please note that though I have tested this method of increasing volume on my Galaxy S4 GT-I9500, I do not guarantee that it’ll work on all versions of the device. Further, do not try the procedure on any your Galaxy S4 with any ROM other than one that is based on stock TouchWiz.

Section I: For Galaxy S4 GT-I9500

This section is only for Galaxy S4 international model owners.


  • A rooted Samsung Galaxy S4

  7. Finally, reboot the phone.

Done! Now you should experience enhanced and louder speaker volume on your Samsung Galaxy S4.

Do it Yourself:

In case you feel the volume too loud for you, you can edit the volume values yourself. The volume gain configuration in the file provided above has following values:

General Volume (Normal, Speaker) increased from 112 to 132.
Ringtone Volume (Ringtone, Speaker) increased from 112 to 132.
Earpiece Volume (Incall, Earpiece) increased from 128 to 132.
Speakerphone Volume (Incall, Speaker) increased from 144 to 154

Here is an example of how you can modify the volume gain values as per your requirements:

Original Code:

Modifier "Ringtone" {
SupportedDevice {
Enable {
{ "Speaker Digital Volume", 112 },
{ "SPKOUTL Input 1 Volume", 32 },
{ "SPKOUTL Input 2 Volume", 32 },

Modified Code:

Modifier "Ringtone" {
SupportedDevice {
Enable {
{ "Speaker Digital Volume", 142 },
{ "SPKOUTL Input 1 Volume", 32 },
{ "SPKOUTL Input 2 Volume", 32 },

  1. is it possible to edit the microphone gain aswell? I’m having a problem while recording videos and sounds, the audio is almost missing or very low to be heard after install some custom roms (CM13 and Resurrection Remix).

  2. i’m on android 4.4.2 with a note 3 and there is no snd_soc_msm_2x_Fusion3 folder whatsoever, any ideas what to do now?

  3. Rakesh, when I am doing the volume mod for Android 4.4.2 on my Galaxy S4, do I need to follow the steps for using CWM recovery. So far I have downloaded one of the volume mods ( mod). I extracted the snd_soc_msm_2x_Fusion3 file and replaced the one on my phone. I rebooted the phone but don’t see a difference. I have a rooted 4.4.2 NC1 Galaxy S4 with stock rom. I’m not trying to do custom roms at this point, only interested in increasing volumes (mainly Bluetooth), so I haven’t gone through the trouble of downloading Safestrap. I was just wondering if this was required or if what I have done should complete the procedure.

  4. Thanks Rakesh. Worked perfect on my rooted I9195 JB stock rom following your Section II instructions.

  5. thanks rakesh i just tried installing megabass zip file but that doesnt work either. i tried and am still reading posts from numerous sites. its brand new s4 mini i9195 with 4.2.2 on it. its all rooted with granted permission. i do appreciate ur time in trying to help. the worst bit is the speaker for ringtone is on back of phone so when i put my phone down on side etc it muffles the sound on top of that they give u a sound that is low in volume. previously asked samsung which twit <– being polite here but thats not what was said to samsung designed this.

  6. I have followed the above steps n its working but the speaker volume is too loud!! like it can be demaged n sound quality is not good ! HOw to edit the speaker values ????

  7. Joined just to comment on this mod it works flawlessly on moderate very impressed. Now my headphones finally have some sound to them. The speaker doesn’t distort on max either, don’t know why Samsung would limit the speaker sound like that though I do understand why they would limit the headphone sound (to protect your ears) but it also helps for when I’m plugging it into my car/house stereo so I’m not turning them up so loud to compensate.

  9. None of the above mentioned applications have been helpfull thus far. I have installed root checker and it seems eventhough I can view the root files, the rooting was not completed successfully as root checker displays “no root”. I have tried using srs rooting agent but still no love. I did however notice that i was reciving a warning message during the rooting process… “an application has tried to access the system and has been blocked”. It seems like the app “knox” has been blocking my rootinh agent from successfully rooting Android 4.3… Any sugestions? It seems that the application cannot be removed…

  10. Mod, strangely enough I am using Root Browser to manage my files still I can not seem to find the Volume.db. Stranger still I can not change any permissions or over write the default config.

  11. I have downloaded and extracted the default zip and tried toe replace but system is failing to replace default. Also can not edit manually… also no volume.db available

  12. Erofs read only file system error.. please tell me how can I paste the downloaded default gain file into root /etc/.. im using es root expl app to root the file.. but I have no access to overwrite the file it is warning me EROFS..

  13. Hi .. I am unable to find volume.db file on etc/volume.db.. but I got default gain.conf file. And when I try to paste default gain file with root browser or root explorer it says operation failed.. help me.. thanks in advance..

  14. right thanks. so after u edit the entry under headphones. i changed it to 132,then saved in notepadpluss++ .. then what do i do? as didnt make a difference

  15. I download already the root checker and when i hit it. It says that my phone has not proper rooted but my phone works at all

    best ragard’s


  16. I was following the instruction you posted in net and i downloded all the suggested application below like root browser and ES file explorer manager but i dont know if where i could get some other requirement like default gain zip and default gain backup zip..since i buy my gs4 international model i dont evev try to do root it. So does it mean that my phone is not rooted yet.
    best ragard’s


  17. Extract the zip. Inside you will see folders and inside them the volume hack files. Just copy/replace the original file on your phone using a root explorer. Fix permissions and reboot. Do not forget to backup the original before replacing.
    Also, some custom ROMs already have volume mods integrated and this might be one of the reasons why you are not noticing any difference.

  18. How do I do this manually on the SCH-I545 or at least verify that it was done correctly? I can’t seem to get it to work (Hyperdrive ROM).

  19. works great, i changed the general volume speaker to 120 because the 132 was too distorted at the highest volume.

  20. Yes, you can do it by modifying the gain values in the “default_gain.conf”. Open the zip (not extract) on your computer, install Notepad++ and edit. Press Ctrl+F and type “Headphones” then edit each entry as per your need.

  21. Read the installation instructions please before asking anything. It clearly says you have to flash the zip file using custom recovery like CWM or TWRP.

  22. Hi I have custom recovery (TWRP) installed on my Galaxy S4 but when I hold down the Volume Up+Home+Power buttons together for about 5-6 seconds till the “Samsung Galaxy S IV” logo blinks for 2 times.Then release the power button only and wait till you see the recovery menu like the pic that you have but it is like the pic that I have attached.

    Please can you tell me what to do for this to work.

    Many Thanks

  23. I have not tested that personally but if the files are the same, and I guess they should be, it should work. Try it but do not forget to backup the ROM first. 🙂

  24. If you can see this file “snd_soc_msm_2x_Fusion3” in system/etc folder on your phone, it’ll work for sure. Use a root explorer and see it.

    Let me know.

  25. I didn’t try loud for that very reason, there have been a few tweaks floating around XDA. The loud ones available there produce a bit of distortion as well.

  26. I’m using the moderate one, definitely raised the volume…. moderately, haha. Anyway, worked well. Thx again. I used TWRP as recovery also, by the way, if that matters.

  27. I just looked through almost every folder on the device. Can’t seem to find it. I’ll keep looking and post here if I find it.

  28. Hmm, the file system is different on US variants. Check the Preload directory. Also browse from other directories on root. The is is present on all Galaxy devices, the location might differ though.
