You won't have to buy a Galaxy Z Fold 3 or Flip 3 to get their software upgrades. Samsung is rolling out a One UI 3.1.1 update that brings many of those phones' multitasking and app resizing features to the original Fold, Fold 2, Flip and Flip 5G.
The Fold line unsurprisingly benefits the most thanks to its larger, tablet-like screen. Features like Multi-Active Window (up to three apps at once) and App Split View (seeing extra content for an app) make that folding display much more useful. You can also force apps to resize and rotate on your Fold, pin your favorites with the Taskbar and mirror your internal display on the cover screen.
Not that Flip owners are out of luck. Drag & Split lets all Samsung foldable owners create a new window for an already-open app, and you can invoke Flex Mode to bring up media controls when the phone is partially folded.
Most of these features are deploying now, although you'll have to wait an extra week if you're using the first Galaxy Fold. Not that you'll likely mind. This could significantly improve the usefulness of your older foldable, and suggests Samsung is eager to earn the loyalty of early adopters — if just to increase the chances that you'll buy another Fold or Flip when you're due for an upgrade.
