I own an S10 Exynos version in India. While I was on One UI 1.X, animations were smooth and I didn't see a lot of stuttering across the OS. But a few days ago I update to One UI 2.0 with Android 10. And now, animations stutters so bad. It is just so ...
I was experiencing the same thing. Animation became jittery and performance as well as battery got poor. Factory reset solved it all for me. Now, it's smooth like butter and battery performance is really good.
Final Update:After doing a factory reset and restoring all the data back to the device, I am finally experiencing the smoothness that was promised.No stutter no lagging. Everything is super responsive and very elegant.
