A Suggestion

[RickDas]

You can see a very transparent animation when you open or close the app it's look very bad, also sometimes background scaling doesn't work and most important there's a touch delay so, Samsung please improve this things

That transperancy must be due to the quick switch between app icon and app ui in animation

Nope it's note bcz of quickly switching apps it'll happen if u open app normally. I'll show u a ss. Samsung needs to improve it
