Generic Android - Custom Rom

[gcarter]

A decade or so ago, was a frequent visitor to XDA Forums to custom mod my HTC phones.

Fast forward to late last year, long story short, picked up a fake Samsung s22 ultra which was a cheap Chinese knockoff with whatever generic android version it has installed
It reports its using Android 12 and that's about it.

In its current state, the performance is very very slow, and can take a couple of seconds to navigate between screens, launch apps etc.
Is there any generic custom roms I could throw at this thing?

EDIT - here's some relevant screenshots

Hello and good morning, @gcarter

Welcome back to XDA! I hope you'll always get the support again you require.
However, prior to your next posting please read the guidances that are stuck on top of every forum like

Note: Questions go in Q&A Forum

If you are posting a Question Thread post it in the Q&A forum. Technical discussion of Android development and hacking. No noobs, please. Device-specific releases should go under the appropriate device forum...

forum.xda-developers.com

and the others. I've moved your thread to Android Q&A unless you want it to be moved to the Galaxy S22 Ultra forum.

Thanks for your cooperation!
