Hello, I have a pixel 5a. Right after updating to 12 I noticed a feature included that will definitely have me dropping all google phones unless I can be remediate it. This is the problem: previously opening an app, any app and then closing an app, any app, the app would just close and it's associated icon would just quietly go back to it's position on the screen without this newly-introduced zooming/shrinking back into place (like all iPhone icons do). It gives me eye fatigue and is annoying that every app I now open, when I close it it does this fancy sweeping back down into position. I think this is called animation and it is horrid. Disabling all animation in the developer options does not turn this off.
Is there some secret way to turn this off as I cannot find any setting in the settings to do so.
Thanks.

 

Thanks both @Dannydet and @Hadron - I changed to Nova and problem solved!
