I’ve been every day driving a book-style foldable cellphone for the previous few months now, and I don’t wish to return to a standard candybar cellphone. Watching movies, studying manga, and shopping the online are all rather more snug to do on the inside display screen of a book-style foldable than on a candybar cellphone. Sadly, my expertise with the software program on the 2 book-style foldables I’ve used thus far — the Samsung Galaxy Z Fold 5 and the OnePlus Open — hasn’t been good, and it’s not due to something Samsung or OnePlus has completed.
I’m certain you’ve heard reviewers say that many apps aren’t “optimized” but for foldables, however what precisely do they imply by that?
Broadly talking, there are 4 classes of software program points that I’ve recognized whereas utilizing book-style foldable telephones. These embrace dimension, structure, consciousness, and benefit. I’ll clarify what I imply by every of those and in addition discuss how Google and OEMs are working to handle them.
My first concern: Measurement
If you happen to evaluate the variety of candybar Android telephones which can be in the marketplace versus the variety of large-screen Android gadgets (which incorporates tablets, foldables, and Chromebooks able to working Android apps), you’ll discover that the previous far exceeds the latter. That’s why it’s no shock that the overwhelming majority of builders give attention to optimizing their Android apps for candybar telephones first. If they’ve the time and sources, they might optimize their app for bigger screens, however many builders don’t.
Builders that don’t or can’t optimize their apps have two choices: Block the app from working on gadgets with bigger screens or lock the app into portrait orientation. The primary choice would shut out some potential customers, so many builders select not to do this. The second choice lets these customers entry the app, though they might must flip their machine 90° to really use it. Apps like BeReal, Authy, Venmo, Zipcar, Lyft, Delta, Chase, and Amex lock themselves to portrait orientation, for instance.
It’s clearly not ultimate that there are such a lot of apps that aren’t optimized for panorama orientation, however forcing builders to tweak their apps to assist what could also be a comparatively small variety of customers isn’t one thing Google can justify. As an alternative, Google discovered an answer that lets OEMs override an app’s orientation choice whereas nonetheless displaying the app in its meant facet ratio.
At a system stage, OEMs can override an app’s orientation choice, permitting them to be proven in panorama mode. By default, this locations the app in a letterbox surrounded by grey bars, however you possibly can stretch the app to fill the display screen if you would like. In Samsung’s One UI, that is completed by going to Settings > Superior options > Labs > Panorama view for portrait apps. In OxygenOS/ColorOS, that is completed by going to Settings > Fundamental display screen > Show dimension. Lastly, in inventory Android, that is completed by navigating to Settings > Apps > Side ratio.
Whereas overriding the orientation choice and facet ratio of an app solves some issues, it results in different issues or just doesn’t tackle some current points. These points must do with the app’s structure.
My second concern: Format
By structure, I’m referring to the position of UI parts inside an app, reminiscent of buttons, tabs, textual content, and pictures. Many apps designed for candybar telephones use a backside navigation bar, i.e., a row of buttons on the backside that lets customers navigate to completely different screens within the app. These buttons are shut sufficient collectively on candybar telephones that they’re simple to achieve with out stretching your thumb, however they’re tougher to achieve when the app is stretched to fill the display screen on gadgets with a lot wider screens. The answer to this downside is for the app to change to a facet navigation rail when it’s opened on a tool with a bigger display screen.
Listed here are some screenshots displaying Gmail on a candybar cellphone with a backside navigation bar, Gmail stretched to fill the display screen of a book-style foldable however with a backside navigation bar, and at last, Gmail optimized for big screens with a facet navigation rail:
In-app navigation isn’t the one structure problem to think about. Ebook-style foldables, when unfolded, have sufficient display screen area to accommodate two panes of content material, but most apps solely present a single pane of content material at a time. Typically, this ends in textual content and pictures being unnecessarily stretched to suit your entire width of the inside show, reminiscent of within the case of the X app.
Making a two-pane structure requires some work on the a part of the app developer, in fact. Many Google apps, reminiscent of Gmail, as proven above, have a two-pane structure, however most apps from different builders don’t.
Some OEMs have applied options that pressure choose apps to open in a two-pane structure, however this solely works with apps which have a multiple-activity structure, because the system basically forces these apps to assist Android’s “exercise embedding” function. Nonetheless, these sorts of options must be particularly coded to assist sure apps, so that you’ll discover that one OEM’s OS can pressure a two-pane structure in a single app whereas one other OEM’s OS can not. A key instance of that is X, which could be compelled right into a two-pane structure on the Honor Magic V2 however not on the Samsung Galaxy Z Fold 5 or OnePlus Open.
Inventory Android, sadly, has no resolution to this downside. Google’s reply is to offer builders the instruments they should create a two-pane structure, no matter whether or not their app follows fashionable Android growth (MAD) tips.
One other layout-related concern is that, even when the app on paper does all the proper issues to assist large-screen gadgets, it doesn’t present customers that optimized structure by default. These Gmail screenshots I shared earlier have been all taken on the OnePlus Open, first on the outer show, second on the inside show in its default portrait orientation, and lastly on the inside show when flipped over to panorama orientation. The OnePlus Open, in addition to the Galaxy Z Fold 5, has a a lot narrower inside display screen facet ratio in comparison with the Google Pixel Fold, which suggests its pure orientation when unfolded is portrait.
This implies you don’t must flip the cellphone 90° to cope with portrait-locked apps, however it additionally implies that apps with a big display screen optimized structure, like Discord and Gmail, received’t present you that structure until you flip the cellphone 90°.

My third concern: Consciousness
This subsequent concern is much more minor in comparison with the earlier two, however it’s one thing that’s occurred to me usually sufficient that I must deliver it up. There are some things that apps must do to develop into “foldable conscious,” and considered one of them is to deal with the change in show dimension that occurs when the person folds or unfolds their machine.
Sadly, I’ve observed that some apps, like Discord, don’t deal with this configuration change gracefully. For instance, I’ve usually discovered that the ship button is hidden off-screen once I fold the machine whereas Discord is open. To resurface this button, I’ve to shut out of the app after which reopen it.
Many foldables even have a hinge angle sensor that apps can take heed to to regulate their UI primarily based on the folded state of the machine. Only a few apps reap the benefits of the hinge angle sensor, although. YouTube is one instance of an app that does. When the machine is half-opened, YouTube’s Premium controls are proven on the backside half of the display screen whereas the video is proven on the high half.
My final concern: Benefit
Talking of apps making the most of options solely discovered on foldables, the final concern I wished to spotlight is that only a few apps are making the most of the truth that foldables have two shows. The Pixel Fold’s Twin Display screen Interpreter mode helps you to present translated textual content on the outer show and the unique textual content on the inside show. This function wasn’t accessible on the Pixel Fold at launch, nevertheless, because it depends on new capabilities launched in Android 14.
Fortuitously, Android 14 makes it attainable for different apps to make the most of each screens on a foldable, so hopefully extra apps get up to date to reap the benefits of this distinctive facet of foldable telephones.
Ebook-style foldable telephones tick all the proper packing containers for me, and regardless of these points, I don’t see myself carrying an everyday candybar cellphone as my private machine anytime quickly. As soon as book-style foldables drop in worth and develop into extra mainstream, I’m hoping their elevated reputation will encourage builders to optimize their apps.
Till then, in case you’re seeking to choose up a book-style foldable just like the Galaxy Z Fold 5, Pixel Fold, or OnePlus Open, then you have to be conscious of the problems I discussed on this article and the potential workarounds which can be accessible or are in growth.
