So , i think everyone knows i hate the new update, so I won't go on about it. I have however learned that on my S24 ultra if you used themes from galaxy most will not work properly on the ui7 update, causing glitches. Delete old themes and use new from the store and I guarantee things will run smoother. Check in my themes for icons wallpapers that are no longer supported in ui7. Hopefully this helps a little guys .
