Galaxy S3, How to modify a file?

[The Evil Overlord]

Hello to all my loyal acolytes

I, your supreme lord of delusional grandeur have returned.

 

Ok, ok, I have a problem, I own a Samsung Galaxy S3.

</end thread>

 

 

Not really.

 

I was comparing the headphone output of My S3 to my Wife's iPhone 4, turns out the iPhone is much louder.

After trying various volume booster apps in play store, I found they did next to nothing.

After spending the day (I may as well have) searching for a way to manually boost the volume, I discovered that the default.gain.conf file needs to be modified.

(the file is under system>etc>) I have tried various methods and file explorers to mod the file, (all it needs from what I've read is to change the value from 50 to anything up to 67) To no avail.

 

I tried rooting the device in the hope to change the attributes to the file, nothing. after getting frustrated to the point of smashing the thing to bits, I decided to recover the phone back to stock ROM.

 

Has anyone here figured out a way to mod this file?

 

I cannot do it through windows as I cannot access those folders regardless of what I do, rooted or stock, (I've tried showing hidden and system files and all that)

 

I know it's not exactly the end of the world as we know it, but if someone has managed to do this, could you spare a minute to help?

OK, not sure how much help this is, but My S2 and Note2 run custom firmwares.  As such there are tools for these firmwares that allow you better access to the hardware - ad one such benefit is being able to ramp up the amplifier :)

Where do you see the file default.gain.conf? I can try a couple of things on my side if I knew where to look. And actually this could be useful for me as well, I've realised that the S4's volume is not too great either, especially when walking around outside. I need to turn it basically to the maximum to hear anything.

That's just it, I tried rooting it, didn't help, I can only guess you're better at it than me

I didn't necessarily mention rooting - I said I run a custom firmware - and should note a custom kernel.  This is what allows me to alter such things.

 

And nah, not better than anyone mate - I just followed tutorials ;)

can you point me to the tutorial?

[Dick Montage]

Afraid not, as I was at home (different PCs) and for different phones.  However, find yourself a firmware/rom that bundles the Perseus kernel.  It will also include STweaks which will allow you to up your amplifier.  Mine allows up to 70% louder :)

Sorry Int, didn't see your post

 

If you get File Manager, or another that you prefer from play store, and set it to view system files, you can navigate to the OS files from it :)

No, I got that bit. I was more asking for the path to the file. There are quite a lot of system folders to trawl through and I'm feeling lazy. :laugh:

ahh, ok if using file manager, press the up button, until you can go no further

from the root directory, navigate (scroll) to system, then from system to etc, from there look for a file called default_gain.conf

looks like it's protected by the kernel (whatever that means) according to another forum

 

might need the help of a wizard at this point

Kernel is the lowest level of OS that talks to the hardware (basic dumb explanation).

 

Hence needing a kernal (and related apps) that allow it to be altered.

Head over to XDA, to the S3 forum. 

 

Link to the Forum where you'll find kernels for the S3

 

Link to the forum where you will find MODs, including volume boost mods

 

XDA is the most complete place for tweaking your Android device.

Thanks man :)

You both deserve the solved mark but alas, I can only mark one of you as solved

[Dick Montage]

Meh, didn't even know about that feature, so don't really care.  Just hope you get your phone sorted.  I know how damn annoying it can be :)
