I've got the same problem on my 1+ Nord. There's lag and stuttering on scrolling in all apps. It's really quite obvious and not a fussy thing that only some would notice. It's in your face, which makes me all the more annoyed by the way most reviewers didn't mention it. Even MKBHD gave the Nord a runner-up mention in his latest "Best Phones 2020" piece. I don't understand. Very Disappointed. The recent 10.5.5 did not help. Hopefully android 11 will help... when we get it... someday.
