Let’s have a look at some of the improvements and advantages that foldable smartphones provide to app development:

  • Extra screen estate: The fundamental concept behind foldable gadgets is to provide consumers with an interactive experience by utilizing a huge screen. The foldable technology combines two screens into one large one.
  • Small size: Users must now pick between a small form factor and a large screen. They receive everything in one gadget with foldable devices. Foldable smartphones can deliver twice the screen size of a standard cellphone.
  • New content types: Creators will be able to develop new forms of content that take full advantage of the greater screen size as a result of the additional screen.
  • Additional features: Modern smartphones have a small screen size that makes it difficult to fit all of the necessary functionality. Foldable devices will enable the development of multi-screen apps that will offer users additional functions on a single screen.

Foldable tablets and smartphones will one day dominate the market of such gadgets, bringing with them a plethora of new options.

Challenges of foldable smartphone app development

Before diving into the details of developing an app for foldable smartphones, it is important to know the challenges you will face as a developer. To create a high-quality and user-friendly foldable application, consider the following factors:

  • Superior Quality

    Nobody is claiming that developing applications for foldable devices is a piece of cake. Remember that foldable phones must have several orientations and a different aspect ratio than regular smartphones.

However, user expectations have not changed. They expect a bug-free environment when using your programme. As a result, you must understand how to design apps for foldable smartphones; else, your app will fail.

  • More Testing

    Foldable solutions offer a variety of use cases and settings. To ensure that there are no flaws lurking in the background, you must test every feature and every usage scenario. More hours and money will be spent on QA and testing the multi-window software as a result.
  • Higher Development Cost and Time

    If you decide to develop a mobile app for a foldable device or modify an existing one, you will be entering a new market. You must design, create, and test your app for a variety of modes and use scenarios. With additional work comes increased expenses and development time.
  • Changes to be made

Following the release of your app to the markets, you will need to make a variety of adjustments depending on customer input. This is especially critical if you currently have an app and want to make it a foldable device compatible.

To overcome the aforementioned challenges of developing foldable mobile apps, it is recommended that you hire professional developers. 

How to build Apps for Foldable Smartphones?

The building of apps for foldable gadgets differs from that of standard websites. It must be kept in mind at all times, from design to development and testing.

Two Screen Tests

Two Screen Tests

Foldable smartphones have two states of the screen: folded and unfolded screen.

When folded, a foldable gadget resembles a standard smartphone or tablet. Users engage with the smartphone and its functions in the same way.

An ordinary smartphone becomes a large-screen device when unfurled. The additional area delivers an immersive experience as well as numerous hurdles for feature development.

The screen’s condition affects the entire user experience. Users typically engage with their smartphones with one hand. They will need to interact with both hands in the unfolded condition. As a result, the location of user interface elements will need to be adjusted correspondingly.

Multi Window State

Multi Window State

As previously said, the primary goal of foldable smartphones is to give customers larger screens and improved multitasking. Users may interact with a few multi-window apps in some cases, so keep this in mind when designing and developing an app for a foldable device.

Screen Continuity

Screen Continuity

For end users, the transition from folded to unfolded should be automatic and seamless. The app’s location and status must be restored. You must limit the quantity of interface layout changes; otherwise, such changes will disrupt the user experience.

Multi-window functionality is well-known in foldable devices. Prior to the release of Android 10, only one app could be restarted when the phone was locked. The most recent versions of Android allow users to run many apps concurrently. All open apps can restore their state without causing others to freeze. When developing apps for foldable gadgets, keep this functionality in mind, which enables multi-window mode.

Factors to consider while foldable smartphone app development

Here are the elements and changes to consider while creating apps for foldable phones.

1. Make it Resizable

One distinguishing aspect of foldable smartphones is that their screens are substantially larger than those of conventional smartphones. Furthermore, most foldable smartphones have a multi-window mode.

As an application developer, you must ensure that the software you create is compatible with both screen size and multi-window mode. The simplest method is to use the code “resizeableActivity=true.”

This code essentially tells the system that your software supports multi-window and resizable screens. As a result, this code assists an app in being compatible with a variety of screens. Foldable phones, freeform windows, and desktop screens are examples of this.

2. Account for the Two States of the smartphone

The most noticeable distinction between a conventional and a foldable phone is that some foldable phones have two modes of operation: folded screens and unfolded screens. This will have an impact on the app’s functionality. Consider the features you want to display on which screen. 

For example, the unfolded screens of foldable phones provide a lot of working space. You can utilize it to give a more enriched experience. Allowing users to navigate with many fingers at the same time is preferable here. It is critical that you design an app that functions well on both screens. 

3. Adjust Screen Ratios

The form factors of foldable cell phones will most likely vary greatly depending on the manufacturer. While some manufacturers prefer extraordinarily high, long, and thin screens, other phones may have bulkier and shorter panels.

It is critical that you test your app for different screen ratios. This will ensure that your software works on as many devices as possible.

4. Ensuring Quality

Each manufacturer is now developing its own form of the foldable phone, just as there are many different types of smartphones available now. Again, app developers must ensure that their apps’ functionality remains optimal independent of the type of foldable on which they are run.
