Just installed beta 2 on my s20 ultra and here's what I've noticed its new
AOD is smoother
When going to recents the "no recent apps" text now animates to the right
When playing songs there is now much better spacing between media controls and the toggles
Theres is now shadow underneath the recent apps
For me the animations are much more smooth
Haven't used it much but will keep you guys updated! If you guys find anything please share!
