How to Turn Off Camcorder or Video Recorder Sounds on a Sprint Samsung Galaxy S2 or S3

I have a Sprint Samsung Galaxy SII that I use on my favorite provider, Ting, and have learned a few things about turning off annoying sounds that are typically not user-adjustable on Sprint phones.

Update: if you do not wish to root your device or want to mute other sounds, check out my guide on muting any sounds with Tasker.

This tutorial was prompted by questions asked on another post, How to Turn of Galaxy S2 Camera Sounds.  This adjustment requires that you have a rooted device, but if your device is already rooted it is a very simple fix.

First, if you do not already have some sort of root file browser, download one - I am using root browser lite in this tutorial - but anything that can change file permission will work fine.

Now open the root browser and navigate to system → media → audio → ui as shown below:

Once you are in the "ui" folder look for two files, "Cam_Start.ogg" and "Cam_Stop.ogg" as shown below:

These are the sound files that make the noise when recording video.  Long press Cam_Start.ogg first and then press "Permissions" as shown below. Once you have selected permissions, UN-check all of the permissions as shown below and press OK:

Repeat this process for "Cam_Stop.ogg", again turning off all of the permissions. Once you have turned off all the permissions the Cam_Start.ogg and Cam_Stop.ogg files should look like this with no read or write permissions:

That should be all you have to do to turn off the video camera sounds. You can learn more about how to turn off the regular Galaxy S2 camera sounds, and how to turn off the boot and power down sounds if you really want to stop all the annoying noises this phone makes :)

How to Mute Boot and Shutdown Sounds on Rooted Sprint Samsung Galaxy S2 or S3

This guide will show you how to easily mute the startup and shutdown sounds on a rooted Sprint or Ting Samsung Galaxy S2 or S3.

Update: if you do not wish to root your device or want to mute other sounds, learn how to silence any sounds on any device with Tasker.

This is a very easy fix if you have already rooted your phone. If you have not yet rooted, I would highly recommend it as you can root the stock roms very easily. I am not going to cover rooting in this post as it is extensively covered by many other people - just google "how to root [your phone] [your software version]" and you will find all the information you need. See the beginning of this post for brief instructions how to root the latest (and final) release for the Sprint Galaxy S2.

So, now that your phone is already rooted, this is the by far the best method to mute the boot up and power down sounds. The screenshots shown below were taken with a Galaxy S2, but should be nearly identical with the Galaxy S3 (let me know if they are different). 

First, if you do not already have some sort of root file browser, download one - I am using root browser lite in this tutorial - but anything that can change file permission will work fine. 

Now open root browser and navigate to system → media → audio → ui as shown below: 

Now find PowerOff.wav and PowerOn.ogg as shown below:

Long press on PowerOff.wav and then select "Permissions." Once you have selected permissions, UN-check all of the permissions as shown below and press OK. The first time you do this your phone will ask if its okay for the app to have root privileges - grant them, and it won't bother you any more. 

Repeat this process for PowerOn.ogg, again turning off all of the permissions. Once you have turned off all the permissions the PowerOff and PowerOn files should look like this with no read or write permissions:

That is it! No more annoying boot and shutdown sounds on the rooted stock ROM.

If you would like to learn more about silencing the Sprint Galaxy S2, I wrote posts on how to silence the camera and video camera as well.

How to Silence or Mute Camera Sounds on Sprint Galaxy S2 Epic 4G Touch Jelly Bean GB27

I have a Galaxy S2 on Ting and recently upgraded to the latest Jelly Bean software. This software update to Jelly Bean 4.1.2 will be the last major upgrade for the Sprint Samsung Galaxy S2. In order to upgrade you have to do so manually, it will NOT be sent OTA to your device, so this is a good time to root as rooting the S2 is about as easy as manually upgrading :)

The camera sounds on the Sprint Galaxy S2 and S3 can be very annoying and very loud if you are in a quiet environment.  This method requires rooting your phone but rooting this device with the stock ROM is extremely easy and adds multiple advantages such as ad blocking, ability to get rid of all the sprint bloatware, and better backup (for example using titanium backup root). 

Please note that this tutorial is for the Sprint Samsung Galaxy S2, but if you have a rooted Sprint Samsung Galaxy S3, the latter section of this post when we start to use the root browser should be the same.

Update: if you do not wish to root your phone, have another device, or want to mute any other sounds, learn how do so with Tasker.

There are plenty of resources our there on how to update to a rooted version of the stock Jelly Bean ROM so I will not go into detail, but will provide links along with the basic steps outlined below:

• As always, backup all your important data to a SD card or your computer before doing anything! 
• Make sure you have the Samsung mobile phone drivers installed for your phone.
• Download the rooted version of the stock ROM (the .exe file) and once it is downloaded right click on it, run as administrator, then extract.
• Open the Odin-OC folder you just extracted and then open the application in that folder named "SPH-D710_GB27_1014481_Rooted_Restore.exe"
• Now grab your Sprint GS2 and turn it off. Then simultaneously hold down the power and volume down buttons. Your phone will ask you if you want to continue by pressing the volume up button, do so, and your phone will enter download mode.
• Plug your phone into your computer via USB and a yellow box should show up in the Odin application (if it doesn't try another USB port and make sure you have the drivers installed). 
• Press "Start" and let it install the rooted Jelly Bean ROM on your phone (it will take a little while).
• If follow the instructions above you shouldn't have any problems, but if you need a more detailed look you can check out this video (ignore his links they are outdated).

Now that you have an updated and rooted phone lets give you the option of turning off those annoying camera sounds. The screenshots are from a Galaxy S2, but should be nearly identical on a Galaxy S3 (if not let me know).

• You will need a file explorer/manager that can obtain root access. Root Browser Lite works and is free, but you can choose any. Download your file explorer app of choice.
• Go to /system/csc/ (shown below)
• Open feature.xml with a text editor (RB Text Editor should be already installed) (shown below)

• Scroll down to the <!-- Camera --!> section
• Find "<CscFeature_Camera_ShutterSoundMenu>false</"
• Change to "false" to "true" (without quotation marks) so that it looks like this:
• <CscFeature_Camera_ShutterSoundMenu>true</ 
• Press "Save" and exit out of the text editor and root browser.
• Restart your phone.

Now when you open the Camera app, click on the gear icon, scroll down to the "Shutter sound" option that has appeared, and turn it off! That should be all. Now you can turn the camera sounds off whenever you want.

I have also written about how to mute the camcorder sounds and mute the startup and shutdown sounds if you are interested.
