Samsung also announced that S10 users will get lots of new features in an update - S20 features maybe?
Of course not every feature will be ported, but some will, like Single take photos or Pro video (yes, it's back!)
Flex mode APIs will be released soon so developers can build apps using flex mode.
The S20 comes with Live Caption and is the first non-Pixel phone to come with it.
The Mi 10 Pro was revealed too. It has all of the features of the regular Mi 10, but adds a bright display (brighter than the iPhone 11 Pro Max), 10x hybrid zoom, and a depth sensor. Again lifted from the Galaxy S20 series.
