This project is no longer maintained!

The whole project has been rewritten in Rust. The Universal Android Debloat is now a real software with a cross-platform GUI. It is still in a early stage of developpement but most features are there. Please do not open new merge requests and issues on this repo.

Universal Android Debloater

DISCLAIMER: Use this script at your own risk. I am not responsible for anything that could happen to your phone.

Summary

I try to maintain a universal tool which removes bloatwares on any Android phones by using ADB.

The main goal is to improve battery performance and privacy by removing unnecessary and obscure system apps. This can also contribute to improve security by reducing the attack surface. The script has a menu that lets you choose what debloat list you want to use. I strongly encourage you to take a look at the lists because the default selection may not suit you. All packages are as well documented as possible in order to provide a better understanding of what you can delete or not.

This script should be safe with the default selection. The worse thing which could happen is preventing an essential system process to be loaded during boot causing then an unfortunate bootloop. If you used the non-root solution, after about 5 failed system boots, the phone will automatically reboot in recovery mode and you'll have to perform a FACTORY RESET. So make a backup!

If you have a rooted device you can also physically delete the apks. Ironically this solution is safer because the script saves the apks before their removal. In case of bootloop you just need to run the script from a recovery with ADB support (e.g TWRP) and restore them.

In any case, you can NOT brick your device with this script! That's the main thing, right?

Features

• Quick search among all the packages of an android device
• Uninstallation of system/user packages (manually or with the debloat lists)
• Reinstallation of system packages (manually or with the debloat lists)
• ADB backup/restore (not really reliable, see the FAQ)
• Device brand detection and auto-selection of the appropriate manufacturer debloat list
• Logging:debloated_packages.txt, remaining_packages.txt, deleted_apks.txt (for root users)
• Root support
• Installation of alternative open-source apps replacing stock apps (list in the WIKI section) (WIP)

NB : The non-root method is NOT a real uninstallation for system apps (see the FAQ)

How to use it

• Read the FAQ!
• Do a proper backup of your data! You can never be too careful!
• Enable Developer Options on your smartphone.
• Turn on USB Debugging from the developper panel.
• From the settings, disconnect from any OEM accounts (when you delete OEM account package it could lock you on the lockscreen because the phone can't associate your identity anymore)

$ sudo apt install android-sdk-platform-tools qpdf zip

$ sudo pacman -S android-tools qpdf zip

$ sudo yum install android-tools qpdf zip

$ brew install android-platform-tools qpdf bash

> adb devices

$ sudo apt update && sudo apt upgrade
$ sudo apt install android-sdk-platform-tools qpdf zip

adb version

$ wget https://dl.google.com/android/repository/platform-tools-latest-linux.zip
$ unzip platform-tools-latest-linux.zip
$ sudo cp platform-tools/adb /usr/bin/adb
$ sudo chmod 755 /usr/bin/adb
$ adb version

$ adb kill-server

> adb kill-server
> adb start-server
> adb devices

• Download the lastest release of Android Universal Debloater.
• Browse through the debloat lists to be sure the default selection suits you.
• Run debloat_script.sh from a Unix terminal.

$ bash debloat_script.sh

NOTE: Chinese phones users may need to use the AOSP list for removing some stock apps because those chinese manufacturers (especially Xiaomi and Huawei) have been using the name of AOSP packages for their own (modified & closed-source) apps.

IMPORTANT NOTE: You will have to run this script whenever your OEM push an update to your phone as some uninstalled system apps could be reinstalled.
