Don't get me wrong, I love my S23U 512 and I don't regret buying it but I encountered some bugs that Samsung should iron out hopefully in next FW, I don't know if you have the same:
-Sometimes recent apps won't open
-Android Auto connection unstable by USB cable at the start, it need 3-4 unplug/re-plug to work (but rare bug)
-Enabling eye comfort shield reduce drastically the colors saturation
-Changing wallpaper won't give me the option to select color palette automatically like it used to do with s22U, now I have to de-activate color palette and re-activate it for the new color palette to show after changing a wallpaper
