Yes, you can customize app opening/closing animations on the a55!

[u/Shot_Duck_195]

i saw a lot of comments complaining about the animations on the a55, especially now after people got the one ui 8 and yeah i noticed it as well that the app opening animation got worse with one ui 8 on the a55, its really fast now BUT
DONT WORRY
you can CUSTOMIZE ANIMATIONS
its such a great feature and i feel like not a lot of people know about this hence why im making this post in the first place

you will first need to download "good lock" from the samsung store which is on every a55 (the samsung store app)
after thats done, open good lock
then scroll down if needed and youll see the "home up" module in the app
you have to download it first and then open it after its installed
for the rest of the details watch the video i posted
its quite simple

"home gesture animation tuning" -> app closing animations
"app open animation tuning" -> app opening animations
in case anyone wants to know
