Yeah, Samsung is pretty bad (or good, depending on your point of view) when it comes to this stuff. I would never root a Samsung phone because of this mess.

The problem is you're effectively stuck with either Google or Samsung if you want decent performance, update availability, spare part support and the security of not having Chinese spyware embedded on order of the Chinese dictatorship. And Google is known for delivering absolute lemons as hardware, with next to zero support to make stuff worse.
