My device is Sprint Samsung Galaxy S III

Model number: SPH-L710

I want to do this, because I want to stop the camera shutter sound. And I don't want to root my device.

If you could do this then the entire security framework of Android would basically be broken, since you could modify system files anytime you wanted. You'll have to modify your device (temp or permanent root or a custom ROM/boot image with root) to access /system. –  eldarerathis Dec 7 '12 at 18:59

Well, the system protects a lot of personal/valuable information by restricting access to certain features and files. For example, your text messages, call logs, emails and the like are all stored on disk somewhere. If you could write to /system without restriction then you could modify or replace the portions of the OS that enforce these rules, bypass all of these restrictions, and access all of the data on the phone; this would mean that apps on your phone could do the same thing, and potentially steal your personal info or use your phone in unsavory ways without your knowledge. –  eldarerathis Dec 7 '12 at 19:07

Also note that it is illegal in some places to mute the camera shutter sound. –  Matthew Read Dec 7 '12 at 19:19

@LiamW We do have a closed question about it, but I don't know much more specifically. –  Matthew Read Dec 7 '12 at 19:24

Why don't you simply ask "How can I disable/turn off/stop the camera shutter sound on may Galaxy S III?" and wait till the answers come in? XY Problem –  Flow Dec 7 '12 at 19:47

There is absolutely no way to do this without root, and for a good reason.

If an app was do do this imagine the havok that would ensue?

You will have to root your device, either temporarily or permanently, to do this.

Which mean I can't turn off the camera shutter sound???!! –  user1843769 Dec 7 '12 at 19:09
    
@user1843769 Without rooting, correct - although some devices have the ability to do it without modifying system values. –  Liam W Dec 7 '12 at 19:10

You could physically remove or block the speaker. That would prevent the camera from making a noise (no, plugging in headphones won't prevent the external speaker from making a shutter sound).

Aside from that, you really do have to root your device. Or at least put a custom rom on your device (which usually requires root or an unlocked bootloader, not to mention that almost every custom rom has root enabled by default).

You could create an updater-script to access the system and mute the shutter sound, without rooting your phone. http://www.freeyourandroid.com/guide/introdution_to_edify

You should include an update-binary and an empty line at the end of the updater-script.

If they aren't rooted, how do they flash? They won't have a custom recovery. –  Liam W Dec 7 '12 at 20:29
