I was very happy when I switched to Android (Samsung to be precise) from good old Symbian 2 years ago. The new land of the free felt like a heaven but one thing that I have been missing since then is the low volume problem on all my Galaxy phones (Galaxy S, S2, S3, Note 2). If you are not at a calm place, you are likely to miss a call because you cannot hear the ringtone. As you know the freedom in the world of Android means getting root privileges on your phone. If you have this, you are like to find a workaround for all your problems.
I have been using a volume boost hack on my S3 for a few months now and it really works. The method has been devised by Meltus from XDA, so all credits and props to him for this amazing solution. If you are not happy with the low volume intensity of your Samsung Galaxy phone, you will notice a surprising increase in the volume loudness. I have tested it on the international Galaxy S3 GT-I9300 and Note 2 GT-N7100 both and it works like a charm. It might also work on phones like Galaxy S2 and Galaxy Note.
The method described here is considered risky and is not meant for noobs. It might soft brick your phone. Proceed only if you know how to restore a soft-bricked device. Further, loud volume might damage the speakers of your device, especially if you increase volume loudness value above 60. Better copy the files just as they are for a good-going. The method requires root access on you phones. Make sure you have rooted your phone. Do not try this method on Samsung Galaxy phone with AOSP, or any other custom ROM that already has volume boost hack.
If you wish, you can edit the volume gain values of your phone by editing the default_gain.conf file with a program like Notedad++. Look below to know what values you need to change. Just edit the file, save changes and replace the original file in System/etc folder using a root explorer.
The volume boost hack files can be installed using two methods, depending on the type of file you choose. First, you can copy/paste the 2 files provided below using a root file explorer. Alternatively, the volume increase hack file can also be flashed through a custom recovery like CWM or TWRP.
If you have not yet rooted your phone, do it now using our handy tutorials from below-

Personally, I prefer the Root Browser app but you can download and install any root file explorer app. Here are a few nice apps:
This method requires the presence of a custom recovery like ClockworkMod Recovery on your phone. If you have it, download the preferred file from below and do the steps given after a jump:
60_sound_mod_update.zip (boot sound on, camera sound off)
63_sound_mod_update.zip (boot sound on, camera sound off)
backup_sound_mod_update.zip (Original file for restoring purpose)
Installing the zip:
Download the preferred ROM and Google Apps (if applicable) from below and follow the instruction below carefully. But as I said above, your phone must be rooted and CWM Recovery installed on it.
When your phone boots up, check the volume of your Samsung Galaxy phone. Do you feel the volume is louder now? Do not forget to share with us in your comments! Cheers!
