I’ve used it for many years. Lineageos is a largest rom sure .
The issue is that google fucks with base android more and more. Now they made it that there is that yellow logo on boot - your android is insecure. Then banking apps are not working.

Updating from android to android on lineage was a chore on oneplus 8t.
And I ended up not being able to rollback to stock because I wanted to trade in for A new model.

It just makes it harder to use roms.
