How much space you get depends on your credit score

My LG C3 not connected to internet and using an HTPC and Nvidia shield is working great so far.

It’s not only a carrier issue but it is an issue only with Samsung’s bought through carriers. Samsung obviously allows that or subsidizes them somehow. AFAIK with Samsung and carrier branded devices they have their own update schedules as well that is separate than just updates from Samsung.

Did you get the phone from a carrier? I’ve had 2 Samsung’s both bought unlocked from samsung and those come with no bloatware and for years I never had anything like that happen. My wife has an S23 from TMobile and has lots of unremovable apps and bloat.
