It arrived this morning, downloading now.
Funnily enough the description makes a lot of the fact that this is One UI 6 and all of the new stuff, doesn't even mention that this is the upgrade to Android 14. Guess Samsung still want you to think of "Samsung" rather than "Android". #samsungpriorities
One odd glitch: after applying the update everything looked unnatural and over-saturated, even though the display mode was set to "natural". Toggling over to vivid and back to natural fixed it. Wonder whether there will be other things where they've applied Samsung's defaults even though they've apparently left the setting unchanged?
