I've just updated from the December update to the January One UI 3 update and I feel a change in gesture animation.
On December update when you swiped up to go home it was quite slow (in a good way), minimal bouncing effect, smooth and refined, it felt like an iPhone swipe up gesture animation.
On Jan update it feels more faster and bouncy, it doesn't feel as smooth and refined anymore and doesn't feel like an iPhone smoothness. I feel like this new animation feels like the one found on One UI 2.5
Of course everyone has personal preference. If any Samsung software engineer is seeing this I'd like to say I quite liked the One UI 3 December update's gesture animation, felt quite smooth!
