I just discovered this amazing app! It lets you remove (or just disable) preinstalled apps like Facebook, Netflix, etc. and system apps like samsung knox apps, diagnostic, bixby, and even One UI (but you must have installed other launcher). You can’t brick your device, worst case it falls into a boot loop and after 5 reboots it will factory reset.
Debloating your device will make it faster, more private and more secure (less atack surface).
The gold standard is to flash a new ROM, but a lot of people dont’t want to, or cannot because either the phone won’t allow (Samsung etc) or it is too daunting. Next we had ADB commands via terminal (hello hours in the terminal). UAD in isolation might seem daunting, but compared to the alternatives, it it is a heaven sent gift, and I’m not even religious.
