Galaxy Z Fold8 Good Lock Settings: 8 Features You Should Try First

Introduction

The Galaxy Z Fold8 already gives you much more screen space than a conventional smartphone, but Samsung’s Good Lock can make that extra space considerably more useful.

Instead of focusing only on cosmetic customization, you can use Good Lock to improve multitasking, add more practical edge gestures, fine-tune audio, customize Quick Settings, and change how the home screen and recent apps behave.

There’s even a Display Assistant feature called Screen Curtain that can keep compatible content running while effectively blanking the display. That can be useful when listening to media through a browser or running an app that normally needs to remain active on-screen.

The key is knowing which Good Lock modules are actually useful. Here are the Galaxy Z Fold8 settings I’d start with.

Galaxy Z Fold8 Good Lock Settings: 8 Features You Should Try First

1. Display Assistant: Keep Apps Running Without Leaving the Screen Fully On

Display Assistant is one of the first Good Lock modules worth exploring because it changes several behaviors related to the Fold8’s display.

One useful option is screen timeout customization by app. Instead of using the same timeout everywhere, you can give certain apps more time before the screen turns off.

That makes sense on a foldable. You might want a longer timeout while reading a document, following instructions, or using the unfolded phone on a desk, but there’s little reason to keep the display awake as long when you’re checking messages.

Another useful option lets you temporarily keep the screen awake for an extended period without permanently changing your normal system timeout.

Screen Curtain is the feature to know about

The standout feature, however, is Screen Curtain.

Screen Curtain effectively blanks the display while allowing supported apps and processes to continue running. Samsung community documentation describes it as putting the display into a low-power state while keeping the active app running.

This creates some interesting possibilities.

For example, if you’re playing YouTube through Samsung Internet rather than the dedicated YouTube app, Screen Curtain may allow playback to continue while the visible display is effectively turned off. It can also be useful for other streaming, setup, or long-running apps that you don’t need to watch continuously.

There’s an important distinction here: Screen Curtain is not the same thing as locking your Galaxy Z Fold8 normally, and it shouldn’t be treated as a replacement for YouTube Premium’s official background-play functionality.

It also won’t necessarily behave identically with every app. App-level restrictions, DRM, media policies, and future software updates can affect what continues running.

If you use Screen Curtain frequently, assigning it to a Side button shortcut can make it much faster to activate.

Consider lowering refresh rate for simple apps

The Galaxy Z Fold8 supports an adaptive refresh rate of up to 120Hz on its displays. That’s great for scrolling and animation, but not every app benefits equally.

Display Assistant can be used to restrict selected apps to a standard refresh rate. Apps such as Contacts or other mostly static utilities are reasonable candidates.

Don’t expect a dramatic transformation in battery life from this setting alone, though. Think of it as a small efficiency tweak rather than a major power-saving feature.

2. MultiStar: Make Better Use of the Fold8’s Main Display

If there’s one Good Lock module that feels particularly appropriate for a Galaxy Z Fold, it’s MultiStar.

Samsung designed the Fold8 around multitasking. One UI 9 supports two-way and three-way split views, and the Fold8’s unfolded 4:3 display gives apps substantially more room than a normal phone screen.

MultiStar gives you more control over that experience.

Force more apps into landscape

Some Android apps still don’t handle landscape orientation particularly well.

MultiStar includes Fold-specific controls that can make apps rotate into landscape even when their normal behavior is more restrictive.

That can be useful when the Fold8 is sitting horizontally on a stand or when you want two apps to share the wide main display.

Just remember that forcing an unsupported orientation doesn’t magically redesign the app. Some interfaces may still look awkward.

Speed up split-screen and pop-up windows

You can also configure faster ways to launch Multi Window.

One useful approach is to keep Samsung’s two-finger split-screen gesture for normal multitasking and configure an additional shortcut for Pop-up view. That gives you quick access to both window styles instead of assigning multiple gestures to the same task.

Enable Multi Focus

Multi Focus is particularly useful if you routinely keep two active apps on the main display.

Normally, changing focus from one window to another can cause the background app to pause or reduce its activity. Multi Focus is designed to help multiple apps continue operating when you switch focus.

It’s useful for combinations such as a browser and messaging app, reference material and notes, or other workflows where you don’t want one side of your workspace stopping every time you touch the other.

App behavior can still vary, so it isn’t a guarantee that every application will continue running indefinitely.

3. QuickStar: Fit More Controls Into Quick Settings

The Galaxy Z Fold8 gives you a lot of display space, but the default Quick Settings arrangement may not use that space exactly the way you want.

That’s where QuickStar comes in.

QuickStar lets you modify parts of the Quick Settings and status-bar experience, including how densely controls are displayed and how the panel responds to swipe-down gestures.

For Fold8 users, a few options are particularly useful.

You can reduce button spacing to fit more controls on-screen, adjust the size of certain panel elements, and configure where you need to swipe to open Quick Settings directly instead of opening notifications first.

On the unfolded Fold8, that last option can be surprisingly convenient. You can dedicate part of the top area to notifications and another part to Quick Settings, reducing extra swipes.

Some current QuickStar versions also provide additional customization for panel components and slider information. The exact options can change with Good Lock and One UI updates, so your menu may not look identical after a future update.

The goal shouldn’t be to cram as many icons as possible onto the screen. Put the controls you actually use every day within one swipe.

4. RegiStar: Turn the Side Button Into a Better Shortcut

RegiStar is one of those Good Lock modules that doesn’t look essential until you start using its shortcuts.

It can customize parts of the Settings interface and assign additional actions to hardware interactions.

One of the most useful options is customizing a Side button press-and-hold action.

Instead of being limited to Samsung’s default behavior, you can configure the action to launch a function or open an app you use frequently.

The best choice depends entirely on your routine. A note-taking app makes sense if you constantly capture ideas. A password manager, smart-home controller, or another frequently used utility may be more valuable for someone else.

RegiStar is best when you use it to eliminate a repetitive action rather than simply adding another shortcut you’ll forget about.

5. SoundAssistant: Get Much Better Audio Control

SoundAssistant is one of Good Lock’s most useful modules, even if you don’t care about visual customization.

Samsung says SoundAssistant has been one of Good Lock’s most widely used tools, and its biggest advantage is simple: it gives you much finer control over audio behavior.

Set different volume levels for different apps

With individual app volume controls, you can configure volume behavior on an app-by-app basis.

That’s useful if one application is consistently too loud compared with another or if you want media and other apps to behave differently.

Change the volume step

The normal volume buttons can sometimes feel too coarse when you’re trying to find exactly the right listening level.

SoundAssistant lets you adjust the volume step between 1 and 10, giving you finer or faster volume changes depending on your preference.

Smaller increments make sense when you often listen through headphones or speakers and want precise control.

Play audio from multiple apps

Another useful option is Multi Sound.

It can allow audio from more than one app to play instead of having one app automatically interrupt the other.

This won’t be useful for everyone, but it fits the Fold8 surprisingly well. If you’re already running multiple apps side by side, being able to control how those apps handle audio makes the multitasking experience more flexible.

6. One Hand Operation+: The Fold8 Needs Better Edge Gestures

The Galaxy Z Fold8 may be lighter and easier to handle than older Fold generations, but its unfolded display is still large enough that constantly reaching across the screen isn’t ideal.

One Hand Operation+ solves that problem with customizable gestures from the left and right edges.

Each handle can respond differently depending on whether you swipe straight inward, diagonally upward, or diagonally downward. You can also assign different actions to short and long gestures.

There’s no single layout that works for everyone, but a practical setup could include:

• Swipe inward for Back
• Diagonal swipe for Quick Tools
• Long swipe for a screenshot
• Another gesture for Auto rotate
• A browser-related shortcut on the opposite edge

The real advantage isn’t any specific shortcut. It’s putting actions that normally require reaching across a 7.6-inch main display within easy reach of your thumb.

You can also change the gesture recognition area, handle position, and sensitivity until accidental triggers are minimized.

There is one current issue worth knowing about. Samsung has acknowledged recent compatibility problems involving One Hand Operation+ and Edge Panels, with a fix expected through an update. If Edge Panel gestures suddenly stop behaving normally after enabling the module, check for the latest One Hand Operation+ update before assuming something is wrong with your Fold8.

7. Nice Shot: Make Screenshots Easier to Manage

If you take a lot of screenshots, Nice Shot is a small Good Lock addition that can save more time than you might expect.

One particularly useful option adds a Delete button to the screenshot toolbar.

That means if you capture the wrong screen—or take a temporary screenshot you only need for a moment—you can delete it immediately instead of opening Gallery later and cleaning up unwanted images.

It’s a minor feature, but those are often the Good Lock settings worth keeping. You configure them once, and they quietly remove unnecessary steps from everyday tasks.

8. Home Up: Make the Fold8 Home Screen Work Your Way

Home Up offers far more customization than most people need, so it’s better to start with a few practical options instead of changing everything at once.

Loop your Home and Apps screens

Page looping allows you to move directly from the final page back to the first page rather than swiping all the way back.

It’s especially useful if you keep several pages of apps or widgets.

Customize folder behavior

Home Up can also change how folders appear and where they open.

A centered folder can be easier to reach consistently, while variable folder sizing prevents a folder with only a few apps from taking up more space than necessary.

Try different Recent Apps layouts

Home Up lets you change the appearance of the Recent Apps screen.

There isn’t a universally better layout here. Try the available styles and choose the one that makes switching apps fastest for you.

Customize the Taskbar

The Taskbar is one of the most important productivity features on a Galaxy Z Fold, and Home Up provides additional customization options for it.

If you regularly switch among the same few apps while the phone is unfolded, spend some time configuring the Taskbar rather than relying entirely on the default arrangement.

That’s where Home Up becomes more than a cosmetic customization tool—it can reduce the number of steps needed to move between apps.

Conclusion

You don’t need every Good Lock module to get more out of the Galaxy Z Fold8.

For most Fold8 owners, I’d start with MultiStar for multitasking, One Hand Operation+ for gestures, SoundAssistant for audio, and Home Up for the launcher and Taskbar.

Then add Display Assistant if Screen Curtain or per-app display controls fit your routine, QuickStar if you regularly use Quick Settings, and RegiStar if you want more useful hardware shortcuts.

Screen Curtain is probably the most unusual feature in this group. Being able to effectively blank the display while keeping compatible content running can be genuinely useful, particularly with browser-based media, but it isn’t a universal background-play workaround and shouldn’t be confused with actually locking the phone.

That’s the bigger reason Good Lock works so well on the Galaxy Z Fold8. The Fold8 already has the hardware for serious multitasking. Good Lock simply gives you more control over how that hardware behaves.

And with a phone that starts at $1,899.99 in the U.S., spending a few minutes configuring the software is one of the easiest ways to make better use of what you paid for.
