How to use full-screen apps on Galaxy Z Flip 4 cover screen

The Samsung Galaxy Z Flip 4 is one of the most fascinating phones out there. The clamshell form factor is wrapped in nostalgia, while the inner foldable display is a true technological marvel. The Galaxy Z Flip 4’s secondary outer display is functional enough for basic information, but if you want to make the most of it, we have some effective ways to use the Galaxy Z Flip 4’s outer display to run full versions of it applications.

These methods also apply to the Galaxy Z Flip 3, which has the same external display.

In the past we’ve talked about how the amount of information included, viewable on the external display, makes it an excellent tool for a digital detox. However, if you’re on the other end of the spectrum and want to use the external display for pretty much everything from watching Netflix to playing intense shooting games, you have the option to do that too. There are three ways to run full-screen apps on the Galaxy Z Flip 4’s external display, and we’ll walk you through the steps for each method in turn.

How to use full screen apps with Samsung Good Lock modules

The first method to enable the outer display full screen utility is an officially supported method. We use Good Lock, a Samsung app that allows you to download a variety of apps that improve the look and functionality of any Samsung smartphone with the One UI interface. As this is an official method, it is also the safest way to run apps in full screen mode on the Galaxy Z Flip 4’s outer display.

First, follow the steps listed below. Note: Good Lock is a versatile app that helps you customize your Galaxy smartphone, but it also has several other modules. We don’t recommend playing around with them without familiarizing yourself with them first, as they can make permanent changes to your smartphone’s interface.

Step 1: Download Good Lock from the Samsung Galaxy Store. If you can’t find it in your country’s Galaxy Store, you can also sideload it with an APK file.

Step 2: Once installed, open Good Lock and look for a module called MultiStar. You can also download it directly from the Galaxy Store or sideload the APK file.

Step 3: MultiStar is not listed in the App Launcher. So go back to the Good Lock app and Look for the MultiStar module – it should be listed at the top of the Life Up tab.

Step 4: Tap MultiStar to open it.

Step 5: Tap the “I ♡ Galaxy foldable” option at the top of the app. From this menu, tap the option Cover launcher widget Possibility.

Step 6: Tap the “+” icon to add apps you want to do on the Galaxy Z Flip 4 cover screen. Don’t be afraid to add a mix of games and entertainment apps. The menu lists a bunch of recommended apps, but you can Tap the down arrow to open the list of all apps.

Step 7: Tap the Cover widget setting option to activate the function. Activate the Toggle cover launcher and type Rearrange to arrange the order of the cover screen widgets. I left the cover launcher at the top, but you can arrange them however you like.

Step 8: Close the clamshell and wake up the cover disc Press the power button or double tap it. Swipe right to Cover launcher widget on the smaller screen.

Step 9: Now, Select the application you want to run and you will be prompted to unlock the phone with the fingerprint scanner before opening the app. This ensures that no one can access important apps from the deck screen without proper authentication.

Step 10: You are done and you can now use the app as you wish. Due to the cramped display, some aspects of the apps – like YouTube Shorts – may not be fully visible. But interestingly, the tiny display lets you use navigation gestures. Even more interesting is the fact that the display supports multi-touch input and you can use it to play hardcore games as well.

How to use full-screen apps with CoverScreen OS

Although the Good Lock method outlined above is the official way to run apps on your Galaxy Z Flip 4’s outer display, it has certain limitations. Not all apps are supported on the outer display, you can only use up to five app shortcuts, and you can’t use the keyboard on the outer display. To circumvent these challenges, developer jagan2 created an app called CoverScreen OS on the XDA forums. As the name suggests, CoverScreen OS completely overhauls the Galaxy Z Flip 4’s external display UI, rather than working within the confines of a single widget screen.

CoverScreen OS gives you much more flexibility, including the option to reply to notifications directly from the cover screen, use flex mode features on the external display, and enable an edge-lighting option that lights up whenever there’s a new notification . To use CoverScreen OS, do the following:

Step 1: Begin, Download CoverScreen OS from the Google Play Store or from the XDA forums.

Step 2: Start CoverScreen OS and grant the required permissions. This includes permissions to view the app on top of other apps, access notifications, and sleep protection even when the app is not actively used.

Step 3: Before you start, tap the tutorial button on the app’s homepage to learn more about the gestures supported in CoverScreen OS and how they differ from the main display.

Step 4: That’s it folks! You can now fold the Galaxy Z Flip 4 and use apps on the smaller display.

With CoverScreen OS, not only can you use apps or control quick settings right from the outer display, but you can also reply to notifications using voice, a T9 keyboard, or a full QWERTY keyboard, and take calls from VoIP services like WhatsApp. You can also use CoverScreen OS to add widgets intended for the main display on that smaller screen.

How to Use Full Screen Apps with SamSprung Launcher

While CoverScreen OS is an incredibly useful app, it has one major caveat: you have to buy the full version of the app for around $20 ($50 for lifetime access on multiple devices) to enable the best features, and that’s not for everyone will do. We have another alternative, in case you prefer a different route, and that’s the SamSprung TooUI Launcher. SamSprung is a third-party launcher designed for the Galaxy Z Flip 3 and the Flip 4’s external display. With it you can run full versions of apps directly on the tiny display.

Here are the steps to get started with SamSprung TooUI:

Step 1: Download SamSprung TooUI from the Google Play Store or get the APK file from Github and install it.

Step 2: Launch SamSprung and grant notifications, usage access, and access permissions.

Step 3: Now fold the Galaxy Z Flip 4 and you will notice a white line at the bottom of the display along with a small icon in the corner. Swipe up on the line to bring up the SamSprung App Launcher.

Step 4: Now open any app. You will be asked to unlock the Galaxy Z Flip 4 with the fingerprint scanner.

Step 5: If the app supports horizontal mode, it will run horizontally. For other apps that don’t do this (e.g. Instagram), the apps will work in portrait mode. This gives you the best experience of both worlds.

In addition to using apps, you can add widgets and swipe horizontally on the screen to access them. You can also tap the icons at the bottom of the display to toggle quick settings. You can also use a keyboard to type and reply to notifications directly from the external display, but SamSprung’s keyboard app needs to be downloaded separately and will cost you nearly $2.

The Galaxy Z Flip 4’s external display can be charged using these simple and easy-to-use techniques. Although the official method is more complex than the others, it’s free and foolproof. At the same time, you don’t have to worry about your smartphone’s security being compromised. However, if you want maximum utility from Samsung’s foldable smartphone, you can look at both options listed above and decide which one you prefer.
