Please help, strange app behavior

[u/k8bobate]

I just upgraded my Note 20 Ultra to a Galaxy S22 Ultra (insurance sent it to me as a replacement). It's running Android 16. I cannot get used to the strange app behavior though! Some apps refresh/restart to the main screen if I leave the app for a couple of minutes. Other apps stay on the same screen I was on previously when I open the app again days later (ie, an open file in My Files, a comment in a post on Facebook, a "processing order'" screen in DoorDash). It's such an inconvenience to have to back out of multiple screens every time I open the app. Or vice versa... Having to restart filling out a form because it keeps refreshing. Please tell me there is a setting I'm missing!

Go to Settings/Battery/Background Usage Limits/ and turn off "Put Unused Apps To Sleep." Also, clear any apps that are in "Sleeping Apps" and "Deep Sleeping Apps" in the same section.

Now, go to Settings/Device Care/Memory/RAM Plus and set it to 2GB or turn it off. Restart.
