S22 ultra laggy after android 15

[Dragann]

I recently updated my phone to Android 15, and it has been problem after problem. It is super laggy, and the keyboard buttons do not work; it swipes on its own, opens and closes apps randomly, or just will not let me swipe, or swipes crazily on its own. Anyone have any idea what to do? It is getting to the point where it is unusable. Also, the phone worked perfectly before I updated it.
