For multitasking on the Galaxy Z Fold8, unfold the phone, open two complementary apps in Multi Window, and save combinations you use often to the Edge Panel. Keep quick replies and short interactions on the cover display; use the larger main display when you need to read, compare, or move between apps.
Choose the right display for the task
The Galaxy Z Fold8 has a 5.5-inch cover display and a 7.6-inch main display. Samsung describes the cover screen as suited to quick interactions and the unfolded screen as a larger workspace. Their listed aspect ratios are 10:16 for the cover display and 4:3 for the main display. Those differences make the cover convenient for short replies, while unfolding gives more room for browsing, notes, email, documents, and video calls. Samsung UK’s Fold8 tips and Samsung Mobile Press list the display sizes.
How to use Multi Window on Galaxy Z Fold8
Multi Window lets you use apps at the same time. Start with two apps that belong together, so each stays available without repeated switching.
- Unfold the phone. The main display is the better choice when you need multiple windows to remain visible.
- Open your first app. Choose the app you will spend the most time in, such as a browser, document, or video call.
- Add a complementary app using Multi Window. Samsung’s examples include a browser beside Samsung Notes, a document beside email, or video beside chat. The exact controls and labels can vary by software version; use the Multi Window controls shown on your device. Samsung Newsroom Indonesia and Samsung US Support describe simultaneous app use.
- Adjust the window divider. Give more space to the app you are actively reading or editing. If either window becomes too cramped to use, return to a two-app layout or switch between apps instead.

Research and note-taking
Keep a browser open beside Samsung Notes. You can consult a webpage while recording the details you want to keep, rather than moving back and forth between the two apps.

Drafting and responding
Place a document beside email when you need to check a message while writing. This pairing is useful when the task requires frequent reference, not simply because two windows are available.
Watching and chatting

When a third app helps
A three-app layout can be useful when all three windows still have enough room for the task. Android Central describes dragging apps from the taskbar into a two- or three-app layout and adjusting the dividers. Treat this as version-dependent guidance: taskbar gestures, labels, app support, and available arrangements may differ with software updates or between apps. If your device offers the taskbar drag-and-drop controls, try adding a third app only when it remains practical to read and use. Android Central’s Fold8 walkthrough covers that approach.
Do these 3 things before closing this tab:

If you often use the same two apps together, save their Multi Window combination to the Edge Panel. Samsung Business Insights says saved pairs can be launched from the panel with one tap. This is most helpful for routine combinations—such as browser and notes or document and email—that you reopen often. Samsung also describes dragging content between emails, documents, and presentations, which can help when the task involves moving information rather than merely viewing two apps side by side. Samsung Business Insights outlines these workflows.

For a desk setup, consider DeX
Samsung describes DeX as an optional desktop-style workflow that uses an external display. For that setup, the phone can connect through an HDMI-to-USB-C cable, and a Bluetooth keyboard and mouse can be paired. These accessories are options for using DeX, not prerequisites for Multi Window on the phone. Samsung does not validate specific accessory models in the cited guidance, so check compatibility for the display and accessories you intend to use before buying them. Samsung Business Insights’ DeX overview describes the workflow.
