My first android was an alcatel with android 3. I loved it, but it was quite bad in many ways, even for the time. It took android a long time to mature.
Let’s hope mobile Linux won’t take as long.

This isn’t the case on their flagships in the EU (not sure which is the reason).
I have never had Facebook or other crap preinstalled since my Samsung Note 10.
That said, samsung best be avoided anyway.
