Display is very laggy, snappiness lost.||| button doesn' switch between apps

[userlQNSpIGilk]

The snappiness of my S21 Ultra is all gone. The window animations, transitions etc are all very slow now. Previous pressing the app ('|||') button twice would allow me to switch between apps, doesn't work anymore. Disgusting performance downgrade.

I have the same issue. Those three vertical lines are a hit or a miss. Does not work always for me. Have to try multiple times before it allows you to switch.

It's a beta, expect behaviour like this ... if you do a search, you'll see many many many other folks with the same issue.

Have you booted to the Maintenance screen and Wiped the Cache Partition?.

if not, search for my post in Tips:

Apps crashing on your beta - try this

There's an extra step in there.

Next thing, go to Developer Options and set the following to 0.5 (see the second screenshot)
