Debloating apps

UAD (Universal Android Debloater) is an ADB tool that can effectively remove system apps without root.

UAD cannot uninstall system apps but can disable them instead, preventing them from ever being loaded into memory. Doing so will help make the phone faster by stopping redundant background services.

Because UAD does not actually uninstall apps it is very safe as you can restore apps from the interface as well. But it still can brick your device if you do not exercise caution.

Installation

If you do not yet have ADB installed, see the setting up ADB page.

To install UAD, see the Getting started page from the UAD Github.

Debloating

This section covers packages specific to the phone and ones likely unlisted by UAD. Use the UAD tool and reference their website for all other debloating information.
