Choosing Apps for Wide Foldable Screens

Foldable phones with wide, tablet-like displays are great for multitasking and media, but not every app takes advantage of the extra space. This guide explains how to identify apps that look and work well on a wide foldable screen, what to look for in app descriptions, and how to test them before committing.

What You’ll Need

• A foldable phone with a wide inner display (e.g., Galaxy Z Fold, Pixel Fold, OnePlus Open).
• Access to the Google Play Store or the manufacturer’s app store.
• Optional: a second device or a friend’s phone to compare layouts.

Step-by-Step

1. Check the app’s description and screenshots. Look for phrases like “tablet optimized,” “large screen support,” or “multi-window ready.” Screenshots that show a split-screen or a multi-pane layout (e.g., a list on the left and detail on the right) are a good sign. If all screenshots are narrow phone-style, the app likely just stretches.
2. Read recent reviews from foldable users. Search the reviews for keywords like “fold,” “tablet,” “large screen,” or “unfolded.” Users often mention if an app looks stretched, has black bars, or crashes when the screen folds. Sort by newest to get current feedback.
3. Check the app’s update history. Apps that are actively updated are more likely to have been optimized for new foldable form factors. Look at the “What’s New” section – if the last update was years ago, it may not support the latest foldable features.
4. Install and test the app on the inner screen. Once installed, open the app with the phone unfolded. Look for:
   • Proper use of space – content fills the screen without giant empty margins.
   • Readable text – not overly stretched or tiny.
   • Responsive layout – buttons and menus are not awkwardly far apart.
   • No black bars on the sides (unless the app is a game that intentionally uses a fixed aspect ratio).
5. Test multitasking and app continuity. Try running the app in split-screen with another app. Does it resize gracefully? Also, fold the phone while the app is open – does it transition smoothly to the cover screen without crashing or losing your place?
6. Check for app-specific settings. Some apps have a “tablet mode” or “large screen layout” toggle in their settings. Look for these and enable them if available.
7. Consider the app’s category. Certain categories are more likely to be optimized:
   • Productivity: Email, calendar, note-taking, and office apps often have multi-pane layouts.
   • Media: Video streaming apps usually fill the screen well, but check if they support the full aspect ratio.
   • Reading: E-book and news apps often adapt well.
   • Games: Many games are not optimized for wide screens and may have black bars or stretched graphics – check reviews first.
8. Use the manufacturer’s app recommendations. Many foldable phones have a curated list of “optimized apps” in the settings or in a companion app. These are tested by the manufacturer and are a safe starting point.

Common Mistakes

• Assuming all apps scale automatically. Android apps that are not optimized for large screens may just stretch, resulting in blurry text or awkward layouts.
• Ignoring the aspect ratio. The inner screen of a foldable is often nearly square (e.g., 1:1 or 4:3). Apps designed for a 16:9 phone screen may not use the extra width well.
• Relying only on screenshots. Screenshots can be cropped or staged. Always check the actual app on your device.
• Forgetting about the cover screen. An app might work great on the inner screen but poorly on the small cover screen. Test both if you plan to use the app on the go.
• Not checking for app-specific issues. Some apps have known bugs with foldables, like the keyboard not appearing in the right place or the camera app crashing when the phone is folded.

Tips

• Use the “App Continuity” feature. Most foldables have a setting that keeps the app open when you fold/unfold. Enable it in the phone’s display settings.
• Force apps to resize. In the phone’s developer options, you can enable “Force activities to be resizable” – this makes some non-optimized apps work in split-screen, though it can cause glitches.
• Look for apps with a “two-pane” layout. For example, an email app that shows the inbox list on the left and the email content on the right is ideal for a wide screen.
• Check the app’s support page. If in doubt, visit the developer’s website – they often list which devices they support officially.
• Use the “Flex Mode” if available. Some apps (like YouTube or camera apps) have a special mode when the phone is partially folded, putting controls on one half and content on the other.

Troubleshooting

• App is stretched or has black bars: This means the app is not optimized. Try the “Force activities to be resizable” option in Developer Options, or look for a “compatibility mode” in the app’s settings. If that fails, you may need to find an alternative app.
• App crashes when folding/unfolding: This is a common bug. First, update the app. If it persists, clear the app’s cache (Settings > Apps > [App] > Storage > Clear Cache). If it still crashes, report the issue to the developer and consider using the app only on one screen.
• Text is too small or too large: Adjust the system font size and display size in the phone’s display settings. Some apps have their own text size settings too.
• Keyboard covers half the screen: Try using a different keyboard app or adjust the keyboard’s height in its settings. Some keyboards have a “split” or “floating” mode that works better on wide screens.
• App doesn’t support split-screen: Check if the app has a “resize” option in the recent apps menu. If not, you can try forcing it via Developer Options, but some apps (like certain games) will not work correctly.

Frequently Asked Questions

Do all apps work on a foldable phone?

Most apps will run, but they may not be optimized for the wide screen. They might stretch, have black bars, or have an awkward layout. Apps that are not optimized still function, but the experience is often poor.

How can I tell if an app is optimized for large screens without installing it?

Check the app’s Play Store listing for screenshots that show a tablet-like layout. Also, look for the “Designed for tablets” or “Large screen” badge on the app’s page. Reviews from other foldable users are also a reliable indicator.

What is the difference between “scaled” and “optimized” apps?

Scaled apps simply stretch the phone layout to fill the screen, which often looks blurry or distorted. Optimized apps have a custom layout that uses the extra space to show more content, like a two-pane view in email or a wider timeline in a social media app.

Can I force an app to use the full screen?

In the phone’s display settings, you can choose “Full screen” for apps that don’t automatically fill the screen. This will remove black bars, but it may crop the edges of the app’s content.

Why do some games have black bars on the foldable screen?

Games are often designed for a specific aspect ratio (like 16:9). The foldable screen is wider, so the game may not support it and instead shows black bars to maintain the correct proportions. Some games have a setting to “stretch” or “fill” the screen, but this may cut off parts of the game.

Are there any apps that are particularly good on a foldable screen?

Productivity apps like Microsoft Office, Google Docs, and note-taking apps like Notion or Evernote tend to have excellent multi-pane layouts. Video streaming apps like Netflix and YouTube also work well, especially with Flex Mode. Social media apps are improving, but many still show a stretched phone view.
