Use Galaxy S II I9100 Volume Key As Camera Shutter / Capture Button

samsung-Galaxy-S-2When the news of a successor to the original Galaxy S I9000 surfaced, Samsung fans were optimistic and wishful that the new Galaxy S II I9100 would not only bring about the a much needed camera flash, but a dedicated camera button as well. With 4.3 inch Super AMOLED Plus screen, a dual core CPU, an 8MP AF camera with flash and the support for 1080p video recording, the Galaxy S II was the God of all phones. Wait a second, where’s the camera button!? Damnit Samsung, not again! So if you still decided to own one of these little pocket monsters despite the lack of a dedicated camera button, there is something you can do about it now, thanks to XDA-Developers forum member IILaryII, and the concept of hardware key mapping. IILaryII has come up with a mod that lets your phones Volume button act as a camera button.

According to the developer, the idea was to use the power button as the trigger, but he was unable to avoid the power menu popup. Not affluent in Java he says, but we don’t mind the Volume keys either, so hats off to him nonetheless! The volume keys only act as a camera trigger in camera mode, not the camcorder for now due to some issues.

With the mod installed, holding the Volume key would allow the camera to focus and releasing the key would take the snapshot. If you just tap the Volume key, it will simply take a snapshot without waiting.

The mod is simply the original camera app for the Galaxy S II that has been modified by the developer. All that needs to be done is to replace the original camera.apk with the modded one.

Want to run with this? We’ll tell you how.

Disclaimer: Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.



  1. To begin, download the modified camera app from the link above and extract it to find a file named camera.apk.
  2. Copy the file to your SD card, run the root explorer app on your phone and navigate to /system.
  3. Mount the partition as R/W. If you’re using Root Explorer tap the Mount R/W button.
  4. In /system go to /app and rename camera.apk to camera.apk.das.
  5. Once the file is renamed copy the modified camera app to /system/app/.
  6. Now re-mount the /system partition as R/O and reboot the device.

All done! Upon reboot, the mapped volume key should work in camera mode as a trigger, try it out. If it did not work and the keys still serve the zoom function, it means that the the original camera.apk was not replaced correctly. Try deleting the original file from the folder and then add the modded one. Be sure to make a backup of the original one before deleting it.
