Not all of it is carrier related. I had an S21 unlocked (from US) and it still included Facebook and their garbage services, Netflix, OneDrive, etc. Also all of Samsung’s first party bloatware and nonsense is prevalent regardless. Not to mention Samsung selling data and their tracking, crippling your phone if you root it or install a custom OS (and in the US outright preventing it entirely), etc. Can’t recommend them or their phones at all, but its unfortunate because they have great hardware, just terrible software.
Yeah, that wasn’t my experience in Australia. Every Samsung I ever had had google apps and Samsung apps preinstalled. None of the rest. And all those baked in apps were easily disabled if they couldn’t be deleted (I couldn’t delete YouTube, but I could disable it so I could run Vanced and not have the normal YouTube app be the default). I suspect that even though you bought a unlocked phone, it came with a bunch of shit baked in cos you are in the US. There’s a lot of shit that is copacetic there (more generally speaking than just phone related) that doesn’t fly in the rest of the world.
As I said, there are other reasons not to use Samsung devices, but all these stories I’ve gotten in this thread have not matched up with the experience I had in over 7yrs.
