Rotate All Apps

One of the best advantages the unique form factor of a foldable smartphone offers is the detailed experiences it provides users whether they are viewing an app in portrait or landscape orientation. Understanding that there’s nothing more frustrating than when a certain app is only available in portrait mode, Samsung has fine-tuned the latest One UI upgrade to make switching your phone from portrait to landscape smoother than ever.

With the new Rotate All Apps feature, your apps will smoothly transition to the proper UX to match the portrait or landscape aspect ratio. When the feature is toggled on in ‘Labs’, even vertically fixed apps can be rotated 90 degrees.

Step-by-step guide: Go to Settings > Click Advanced Features > Go to Labs > Click on Auto rotate apps > Choose between two options: Keep app’s orientation or Match phone’s orientation

With customizable aspect ratios, you can maximize the benefits of your foldable smartphone’s Infinity Flex Display. Say you are scrolling through your friends’ latest social media posts and want to view them in full screen, without the black bars on either side, only to find that the size of the app is fixed. One UI 3.1.1 now lets you change the size of the app so that you can fully immerse yourself in their photos and videos. To get the most out of Samsung’s expansive foldable displays, simply enable this feature in ‘Labs’.
