Remove bloatware on Galaxy Devices
How to remove bloatware and make any Galaxy or Android device fasterDroid Views

Samsung Galaxy smartphones and tablets can now run faster thanks to the release of a debloater script by the industrious XDA member blaz1nr.

The debloater script tool has been tested with several Galaxy devices to ensure maximum compatibility. It allows you to remove all those unwanted apps and native add-ons from Samsung, and consequently make your device run faster.

The debloater script reportedly allows users to reduce the size of the ROM by up to 400MB by removing bloatware including apps like Gmail, Google+, S Voice, Amazon app and Facebook messenger, besides a bunch of carrier-based bloatware added by AT&T's Uber and Home.

Galaxy users can back up their important data and settings on the device via custom recovery tools such as CWM or TWRP recovery before using the debloater tool, so that one can restore the device to original state and then reinstall the affected or missing apps easily from Google Play Store.

The debloater script is known to delete some useful apps alongside the unwanted ones. Hence, if you want to prevent such a happening you must edit the script manually as follows:

  • Extract the zip file of debloater tool to a separate folder. You will see a single folder called "META-INF" after extraction.
  • Open the folder and look for the updater-script. You should see the delete-recursive command for all apps that are meant to be removed by the script (by default).
  • If you want to add an exception for a certain app on your phone that you don't want to delete, just add a # tag at the beginning of the command line as shown in the example below:

For example: Change the line from: delete_recursive("/system/app/Gmail2″) to #delete_recursive("/system/app/Gmail2″);

  • Repeat this step for all apps that you want to retain. Then save the updater-script file, and create a zip of the META-INF folder again in a similar format like the original you downloaded.
  • Alternatively, just open the updater-script file in the META-INF folder and open it with Notepad++ file editor on PC, and then save it.
  • Choose Yes when prompted to save the modified zip file that includes the modified updater-script with necessary commands for bloatware removal.

IBTimes UK reminds readers that it will not be held liable for any damage to device during or after the debloater tool installation. Users are advised to proceed at their own risk.
