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).
What’s wrong with Samsung Knox?
Know is an MDM. (Device management software)
It has root level access to everything on your device AND built in tools to allow it all the be remote managed.
