I have an S21 FE, which despite its name is only a year old.
Updates are not timely. We often get updates a month behind, sometimes even two. I remember in early Jan we were still on the Nov security patch. Google is faster, and often Oneplus is faster. They are probably 2nd or 3rd for update timeliness. Better than Moto, at least.
Bloatware...depends on your definition. I consider their stupid Google app copies of everything bloatware, but maybe not everyone does. Most cannot be uninstalled.
Other bloatware...I seem to remember it had FB, LinkedIn, and some Microsoft apps. Last time they also wanted to install TikTok.
That said, I was able to disable everything via adb and got it to a state I like, so it is possible. But it would be nice to be able to do so without resorting to adb.
I like the phone fine, but my next phone will not be a Samsung.
