SO Today I finally got update on note 20 ultra in Canada, after updating everything feels super buggy, slow, frame drops to 60hz constantly and lags. It was super frustrating. So I finally factory reset my phone and guess what so many issued got fixed and the ui feels much smoother. I recommend every single user who get one ui 4.0, just dont forget to factory reset. You'll see day and night difference!
Don't know how many times, I along with others here on Samsung Members, have repeatedly posted that we always perform a Factory Reset after any Android version update.
