UI Design Guidelines
Apps in General
Allow the app to be used in landscape orientation for basic app usability in the Horizontal Swivel Mode. However, if an app can’t be easily used in landscape orientation due to a hardware component’s location such as the fingerprint sensor or NFC, an exception can be made.
Do / Do Not
When swiveling up the device to a T-shaped position, users should be able to expand an app and use the Main screen horizontally along with the Second Screen to maximize usability. In the case of apps related to creating or viewing content, allow the app to expand to the Second Screen to utilize the extra space.
Example 1: Creating content, Example 2: Viewing content, Example 3: Covering content minimally
Expandable App > Second Screen
When designing an expandable app, the UX/UI can be freely designed to suit the app's features and characteristics. For example, a controller can be set to be conveniently used in one hand. When watching content on the Main screen, related content or additional details about the video can be shown without getting in the way of a user watching.
