App design guide for foldable phones

Overview

Galaxy GameDev Partners

Within the next few months, mobile devices will be introduced with new form factors. First of these form factors that will be offered in the market are foldable phones. Soon, various types of form factor devices will be released.

For upcoming new form factors on devices, the teams at Samsung and at Google Android hope that app developers will look first at this design guide as the first step.

App continuity

Users will be able to control multiple displays on one mobile device. The apps will be displayed on different screens to suit the user's preferences, as they will be switched between the screens. As a result, apps are needed to be prepared to switch between multiple screens using different screen attributes (resolutions, densities, and etc).

Users also can unfold the device to have an immersive experience with the current task. Therefore when user unfolded the device, the current task must continue seamlessly into an unfolded display.

Multi-window

A bigger screen real estate on foldable devices renders multi-tasking into an engaging experience.

Android 7.0 supports displaying more than one app at the same time. In addition, when switching to a large screen such as a foldable phone case, users can use two or more apps on split-screen mode. There may be instances that the app may stop functioning whenever moving the focus from one to the other. To mitigate this, you will need to check the documentation on supporting the app with multi-resume in multi-active window mode of the device.
