My S20+ got quick toggle for Bedtime mode.Some new features reportedly include a Bedtime Mode quick setting toggle, faster app opening speed, faster camera, faster pop-up menus, faster fingerprint reader, improved heat management, and slight improvements to some stock apps (Clock, Contacts, Samsung Internet, Weather). Your smartphone might have already received this update and it is hard to see some of those changes, so you should not get too excited about this new version of One UI.
