How to Effectively Develop Apps for Foldable Smartphones?

Developing apps for foldable smartphones requires careful consideration of the unique features and capabilities of the device screen.


When initiating the design of a mobile app for foldable smartphones, consider these five essential aspects.

  • Two Screen State

Two Screen State

Designing for foldable smartphones involves accommodating two primary screen states:

In its usual folded state, the device behaves like a traditional smartphone, with a single screen. It’s crucial to ensure that the app’s layout and content remain coherent even when the screen is folded. 

In the unfolded state, the app should take full advantage of the expanded screen of real estate. This presents an opportunity to provide users with enhanced multitasking, more information visibility, and an immersive experience. 

Multi-screen app development requires anticipation of how users will interact with the app as they switch between these two states. 

  • One or Two-hand App Design 

With foldable phones, users might interact with the device using one hand in the folded state and both hands in the unfolded state. The app design must ensure essential actions and controls are easily reachable and accessible in both usage scenarios, optimizing convenience and comfort for users.

  • Multi-Display Support

The primary goal of foldable devices is to offer users larger screens and enhanced multitasking capabilities. App design should align with this purpose, allowing users to surf through features that enable seamless multitasking, split-screen views, and efficient content navigation that enhances the foldable device user experience. 

  • Muti-Resume


Multi-resume is a feature introduced in Android 10 and later versions that optimizes app multitasking on foldable devices. Before Android 10, running two apps simultaneously would pause the activity in the background. With multi-resume, apps can run independently in split-screen mode, maintaining their active state even when one app is in the background. 

  • Screen Continuity 

This pivotal feature in foldable devices ensures a smooth transition and consistent experience when an app is moved between different screen configurations.

For instance, when an app is opened on the cover display of a foldable device and then unfolded to reveal the larger main display, screen continuity ensures that the app seamlessly transitions and adjusts its layout, content, and functionality to fit the new screen dimensions, providing a cohesive user experience. 

4 Challenges to Acknowledge Before Developing Foldable Device App
