Mobile app development

There was a time when owning a smartphone was associated with luxury. Only rich ones could afford them.

But at the start of the 21st century, the smartphone market exploded with dozens of new brands, not only making the price range affordable but also introducing some exciting new features.

Foldable smartphones instantly grabbed the attention of people. Foldability was a unique feature, people could treat their phone like a brochure or leaflet while reading something on it.

And despite the constantly evolving technology and new trends, foldable devices are still here. Samsung, most notably, produces such phones that people still enjoy using and holding in their hands.

If you’re a mobile app developer, you’ve got to think differently when creating an application for foldable devices. Here are some of the factors and alterations to consider in this regard:

1.Create a Resizable App

Since you’re developing an app for foldable smartphones, you must consider the size of such phones. Their screens are significantly larger than traditional phones. Also, these phones are equipped with multi-window mode.

So it’s your responsibility to design an app that’s compatible with both sizes of a screen as well as the multi-window mode. Do some research and find out a simple line of code to make your app resizable according to the mode in which it’s opened.

2.Consider the Two States of the Phone

It’s important to account for the two states of the phone. They both are different from each other. A simple phone will not have a folding feature while the foldable one will work differently.

The foldable phones can be used with both folded and unfolded screens. While designing the functionalities of your app, consider the foldability feature of an app.

Normally, foldable screens have a lot of space on the screen compared to unfoldable ones; the latter is quite rigid. A user has more freedom and space to work with when he’s on a foldable screen.

Be creative and think out of the box. Introduce features that will give the foldable smartphone users a feeling of pride.

3.Make Your App Capable of Handling Multi-Window Mode

A multi-window mode is a mode in which two apps run simultaneously on the same screen. This is only possible on foldable screens — and this is what makes them different from the traditional screen.

But there’s one aspect you need to take care of while designing your app — make it capable of handling multiple apps at the same time. Consider the space your app will occupy, the multi-tasking capabilities of a device, and changes in the app accordingly.

4.Screen Continuity

As said before, there are two states of such phones — folded and unfolded. As a developer, it’s your job to make this experience a seamless one for the end-user. Minimize the number of interface layout shifts to prevent any interruption in the user experience.

5.Adjust Screen Ratio

Foldable devices have different screen ratios, that’s because some have short and bulkier screens while some have long and thin screens. It’s the developer’s responsibility to design an app that fits both types; the app must adjust itself on all foldable screens.

To do it, implement minAspectRatio and maxAspectRatio and find out if the screen is compatible with the device or not.

6.Ensure 100% Quality

Most importantly, you should ensure that your app caters to all smartphones, not just the foldable ones. As we have multiple smartphone brands all across the world, they keep coming up with their own types of smartphones.

It’s the mobile app development company’s responsibility to make sure that the functionality of the app remains optimum, irrespective of the fact the device it is operated on.

Therefore, it’s recommended to plan before you implement. Figure out how many devices your app is supposed to support. Do your research about the screen ratio and resolutions of different foldable phones.

There’s not much you can do about the future technology, but you can take the oldest ones into account before developing your next app.

During the development phase and after completion of a project, run your app on different foldable screens and analyse its performance. You will learn where you need to improve to make your app perfect for all screens and devices.

7.Take Feedback & Improve

Rarely will you reach the most perfect version of your app in the first attempt. You have to keep iterating to meet the increasing requirements of the users. With every new phone launch, developers bump into new challenges.

So the only way to create viral apps is to take feedback seriously and improve your app. The same goes for the apps designed for foldable screens. Keep an eye on the market trends, note specifications of the latest specifications, and reviews on the Play store, so you know how to improve your app further.

Final Thoughts

Mobile app development is a skill that requires both technical expertise and knowledge, as well as creativity. And when it comes to foldable smartphones, you have to be careful because of the varying screen sizes and the user requirements.

A foldable phone user is likely to use multiple apps at the same time, so your app must be optimized for speed. Likewise, it should render a seamless transition experience for different screen modes.

While designing your next mobile app, keep these tips in mind to cater to the needs of all users.
