The Galaxy S26 Ultra and Galaxy Z Fold8 Ultra can both handle demanding multitasking, but they are designed around fundamentally different workflows. The S26 Ultra gives you a powerful conventional smartphone with Samsung DeX when you need a larger desktop-style workspace. The Fold8 Ultra gives you an 8-inch internal display that lets you run multiple apps side by side without connecting to another screen. For people who regularly read, message, research, edit documents and manage information simultaneously, that physical screen difference is the Fold’s most important advantage.
The question is therefore not whether the Fold8 Ultra is more powerful. Both are flagship devices, and the S26 Ultra also supports DeX. The more useful question is whether your daily tasks benefit enough from a tablet-sized workspace to justify carrying a more specialized foldable. If most of your multitasking means switching between two or three apps, the S26 Ultra can be sufficient. If multitasking means keeping several sources visible at once, the Fold8 Ultra changes what is practical on a phone.
The biggest difference is the screen, not the processor
The Galaxy S26 Ultra has a conventional large smartphone display.
The Galaxy Z Fold8 Ultra has two usable screen configurations:
- a 6.5-inch cover display
- an 8-inch internal display
Samsung specifically positions the Fold8 Ultra’s 8-inch screen around Multi Window, document work and side-by-side applications.
That changes the meaning of multitasking.
On the S26 Ultra, you can move rapidly between applications.
On the Fold8 Ultra, you can often see those applications simultaneously.
That distinction is easy to underestimate until you use it for information-heavy work.
Galaxy Ultra vs Fold multitasking at a glance
| Multitasking factor | Galaxy S26 Ultra | Galaxy Z Fold8 Ultra | Why it matters |
|---|---|---|---|
| Main mobile workspace | Conventional smartphone display | 8-inch unfolded display | Fold gives substantially more room for simultaneous apps |
| Split-screen work | Available through Samsung’s software features | Designed around large-screen Multi Window | Fold makes side-by-side use more practical |
| Multiple apps visible | Possible, but constrained by phone dimensions | Two- and three-way layouts are more usable | Fold reduces constant app switching |
| Quick everyday tasks | Simple and familiar | Cover screen provides phone-like access | Ultra is easier when you only need one app |
| Samsung DeX | Supported | Supported | Both can become desktop-style workstations with a compatible display |
| External-monitor workflow | Strong | Strong | DeX reduces the Fold’s unique advantage when a monitor is available |
| Document/spreadsheet work | Good for viewing and editing | More comfortable on the 8-inch screen | Fold provides more usable workspace |
| Messaging while researching | Frequent app switching or constrained split view | Side-by-side layouts are more practical | Fold keeps context visible |
| Portability | Conventional smartphone | Phone when closed, tablet-like when open | Fold trades simplicity for flexibility |
| Multitasking advantage | Fast app switching and DeX | Large-screen simultaneous workflows | Different approaches rather than simply more power |
Samsung’s current One UI and DeX features vary somewhat by application and software version, so not every app supports every multitasking arrangement.
What multitasking actually means on the Fold
The Fold8 Ultra is not simply displaying a larger version of the same phone interface.
Its large internal screen gives Samsung’s Multi Window system room to place applications beside one another.
Samsung says the Fold8 Ultra supports side-by-side workflows and app pairs, allowing combinations such as Calendar and Messages to be reopened together.
That makes the Fold particularly useful when one application provides information for another.
For example:
Research: browser on one side, notes on the other.
Travel planning: maps alongside messages or booking information.
Business: spreadsheet alongside email or a team chat.
Writing: reference material beside a document.
Content creation: editing application alongside a script, reference image or browser.
The benefit is not that the phone can technically keep multiple apps open.
Modern smartphones already do that.
The benefit is that you can keep the relevant information visible while working.
The S26 Ultra is better at switching; the Fold is better at seeing
This is perhaps the simplest way to understand the distinction.
Suppose you’re writing an email based on information in a web page.
On the S26 Ultra, you can open the browser, read the information, switch to email, write, switch back, check the source and return to email.
The process works.
On the Fold8 Ultra, you can potentially keep the browser and email visible at the same time.
The number of taps decreases.
More importantly, your working memory has less to do because the reference material remains on screen.
That can make a bigger difference than raw processor performance for knowledge work.
Three-app workflows are where the Fold starts to justify itself
Two-app split-screen multitasking is useful on many large smartphones.
Three simultaneous applications are much harder to make comfortable on a conventional phone.
Samsung highlights two-way and three-way Split View on the Fold8 series, with layouts designed around the wider display.
Consider a work scenario involving:
- a browser
- a document
- a messaging application
On a conventional smartphone, this becomes a sequence of switches.
On the Fold, all three can potentially remain available in a single workspace.
That does not mean every three-app configuration will be comfortable.
The more windows you add, the less space each application receives.
But the Fold gives you enough physical screen area for the option to become genuinely useful rather than merely technically possible.
App support still matters
There is an important qualification.
Samsung’s multitasking features do not magically redesign every Android application.
Some applications respond well to resizing.
Others have limited layouts.
Samsung itself notes that certain side-by-side Multi Window functions work only with supported applications.
This means the Fold’s potential depends partly on the software you use.
If your daily applications are well optimized for tablets and foldables, the advantage can be substantial.
If your workflow relies on applications designed exclusively around a narrow phone interface, the benefit is smaller.
Before buying a Fold primarily for work, it is worth checking the applications that actually occupy most of your day.
App pairs are more useful than they sound
One of the less glamorous Fold features can have a disproportionate effect on repetitive workflows.
Samsung allows supported applications to be saved as an app pair so that they can be launched together in split view.
That is useful if you repeatedly perform the same combinations.
For example:
- Email + Calendar
- Browser + Notes
- Teams + OneDrive
- Messages + Maps
- Spreadsheet + Calculator
Instead of rebuilding the workspace each time, the pair becomes a reusable workflow.
The value is greatest for people whose work follows predictable patterns.
The Fold also changes how you move between phone and tablet modes
The Fold8 Ultra can start an application on its 6.5-inch cover display and then open to the 8-inch internal display while maintaining the task. Samsung specifically describes this transition as a way to continue working without losing your place.
That gives the device two useful personalities.
Closed:
phone
Open:
compact tablet
You don’t have to commit to the large interface for everything.
A quick message can stay on the cover display.
A spreadsheet can move to the internal display.
A long document can be opened fully when you need more space.
That flexibility is central to the Fold’s productivity proposition.
The S26 Ultra has one major counterargument: DeX
It would be misleading to portray the S26 Ultra as a device without serious multitasking capability.
Samsung DeX allows compatible Galaxy phones, including the S26 series, to connect to a monitor or TV and provide a desktop-style interface. Samsung says users can work across multiple applications in resizable windows and use a keyboard and mouse.
That changes the comparison.
If you already work at a desk with a monitor, keyboard and mouse, the S26 Ultra can become a surprisingly capable workstation.
You do not necessarily need a foldable to get desktop-style multitasking.
But DeX requires a different setup
This is where the Fold retains its advantage.
DeX typically means having access to:
- an external display
- compatible connection or wireless display support
- keyboard
- mouse, if required
The Fold8 Ultra can provide its large multitasking workspace in your hands.
Samsung also supports DeX on the Fold8 Ultra, so the Fold can scale from its internal screen to an external monitor when needed.
That gives the Fold two levels of productivity:
8-inch mobile workstation
and
desktop-style DeX workstation
The S26 Ultra primarily gives you:
large smartphone
plus
DeX when connected to a larger display.
DeX makes the Ultra more competitive for office work
If you spend most of your workday at a desk, the Fold’s internal display advantage becomes less decisive.
Connect either phone to a suitable monitor and the workspace expands dramatically.
Samsung says DeX supports resizable windows, drag-and-drop operations, keyboard shortcuts and mouse navigation.
In that environment, the physical difference between the S26 Ultra and Fold8 Ultra becomes less important.
Your monitor is doing the heavy lifting.
The Fold becomes more valuable when you need to perform the same kind of work without the monitor.
The Fold is especially useful for mobile professionals
Consider someone who spends the day moving between:
- meetings
- airports
- client sites
- cafés
- public transport
- hotel rooms
A conventional smartphone plus laptop is still a powerful combination.
But the Fold offers an intermediate option.
You can review a presentation, respond to messages, inspect a spreadsheet and research a topic without opening a laptop.
Samsung explicitly positions the Fold8 Ultra as a mobile workstation that can consolidate phone, tablet and PC-like capabilities through its large screen and DeX support.
That does not make it a complete laptop replacement for everyone.
It does reduce the number of situations in which you need one.
Document work is where the 8-inch screen earns its keep
Long documents are difficult on conventional smartphone screens.
You can read them.
You can edit them.
But the amount of content visible at once is limited.
The Fold’s 8-inch display provides more vertical and horizontal room for documents, PDFs and spreadsheets.
Samsung specifically identifies document review, spreadsheet work and photo examination as use cases for the larger display.
For someone who frequently reviews contracts, presentations, reports or financial documents while traveling, this can be more important than processor benchmarks.
The difference is primarily information density.
You can see more without constantly zooming, scrolling or switching views.
Spreadsheets reveal the difference particularly well
A spreadsheet is one of the worst workloads for a small phone screen.
Rows and columns quickly become compressed.
The Fold’s larger display does not turn it into a full desktop spreadsheet environment, but it gives you more room to inspect data and navigate the document.
That makes it useful for:
- checking figures
- reviewing tables
- approving documents
- making small edits
- monitoring dashboards
For complex spreadsheet construction, a laptop or desktop remains more practical.
The Fold’s advantage is being able to do useful spreadsheet work when you don’t have one.
Messaging becomes more useful alongside another app
The ability to keep a messaging application visible while doing something else is one of the most practical uses of the Fold.
Imagine planning an event while keeping a group conversation visible.
Or checking a client’s message while reviewing a document.
Or following directions while keeping a conversation open.
On a conventional phone, the two activities compete for the same screen.
On the Fold, they can coexist.
This is where Samsung’s Now Nudge feature also becomes relevant.
Samsung says Now Nudge can recognize certain contexts and suggest actions, such as adding a meeting or dinner plan discussed in Messages to Calendar, while keeping the original conversation visible.
The useful part is not the AI label.
It is the preservation of context.
AI can reduce some multitasking friction
Samsung’s newer foldable software increasingly treats multitasking as a workflow rather than simply a collection of split-screen commands.
Now Nudge is an example.
Instead of manually deciding which second application to open, Samsung says the system can suggest a relevant next action based on what you’re doing.
There are limitations.
Samsung notes that Now Nudge requires a Samsung account, works with supported applications and does not guarantee accuracy.
So it should be viewed as an assistance layer rather than an autonomous productivity system.
The underlying advantage remains the Fold’s screen.
AI can suggest the next application.
The large display gives that application somewhere useful to live beside the current one.
The S26 Ultra remains better for simple tasks
There is a cost to having a device built around a large internal display.
You have to open it.
For many everyday tasks, that is unnecessary.
Checking:
- a notification
- a short email
- a message
- a calendar appointment
- a quick web result
is perfectly comfortable on a conventional flagship.
The S26 Ultra’s straightforward design therefore has an efficiency of its own.
If your definition of multitasking is mainly rapid switching between apps, the Fold’s additional screen may provide less benefit than you expect.
Multitasking is not the same as having more RAM
It is tempting to judge multitasking by memory capacity.
That is only part of the story.
More memory can help a device keep applications available in the background, but the productivity advantage of the Fold comes primarily from display area and software layout.
A phone can have plenty of RAM and still be awkward for simultaneous work if the screen is too small.
Conversely, a large screen does not guarantee good multitasking if applications do not support resizing.
The best experience comes from the combination of:
hardware + display + software + application support.
The Fold’s larger display can reduce context switching
This is perhaps the most important long-term benefit.
Every time you switch from one application to another, you have to reconstruct some context.
Where was that figure?
Which message contained the address?
What did the webpage say?
Which paragraph was I editing?
Keeping relevant applications visible can reduce those interruptions.
This is why the Fold’s multitasking advantage is more significant for information-heavy work than for ordinary smartphone use.
The more your work depends on comparing information from several places, the more useful the large screen becomes.
But more windows can also create clutter
There is a point where multitasking stops helping.
Three applications visible simultaneously can be useful.
Four or five can become visually crowded.
A larger display provides more room, but it does not eliminate the human limits of attention.
The Fold should therefore not be treated as a reason to keep every application open.
Its real value is choosing the two or three pieces of information that need to remain visible together.
Good multitasking is about reducing unnecessary switching, not maximizing the number of windows.
The Fold can be more useful for research
Research is one of the strongest use cases.
You might need:
- a browser for source material
- notes for recording information
- messaging for communicating findings
On a conventional phone, this means repeated switching.
On the Fold, supported layouts can keep the relevant applications together.
Samsung specifically describes researching and planning as use cases for the Fold8 Ultra’s multitasking system.
For students, journalists, analysts and professionals who regularly gather information from multiple sources, this is one of the Fold’s more meaningful advantages.
It is also useful for content creators
Content creation frequently involves several forms of information at once.
You might need:
- a video editor
- a script
- reference footage
- cloud storage
- messages
- a browser
The Fold’s display makes it easier to move between these elements without abandoning the main task.
Samsung also highlights photo editing through the Fold8 Ultra’s large-screen workflow and DeX.
For serious video editing, desktop software remains substantially more capable.
But for quick edits, publishing and mobile content management, the Fold can reduce the need for another device.
Where the S26 Ultra can actually be preferable
The Fold’s multitasking advantages do not mean everyone who multitasks should buy one.
The S26 Ultra makes more sense when your workload consists primarily of:
- short app sessions
- rapid communication
- notifications
- conventional email
- single-document editing
- occasional DeX use
- quick information checks
It is also simpler to operate one-handed.
And if you already carry a tablet or laptop, the Fold’s built-in large display may duplicate hardware you already own.
The laptop question is crucial
The Fold’s value changes depending on what it replaces.
If you already carry:
phone + tablet + laptop
the Fold may reduce the need for the tablet in some situations.
If you carry:
phone + laptop
the Fold may occasionally reduce how often you need the laptop for lightweight work.
If you carry:
only a phone
the Fold can provide capabilities that a conventional phone simply cannot reproduce as comfortably.
The question is therefore not only whether the Fold is better at multitasking.
It is whether its multitasking capabilities replace another device or merely duplicate one you already carry.
DeX makes the Fold closer to a complete mobile workstation
The Fold8 Ultra can connect to an external monitor and run Samsung DeX, creating a desktop-style environment with resizable windows and conventional peripherals.
That means the Fold can operate at three levels:
Closed: quick phone tasks.
Open: tablet-like multitasking.
Connected to a monitor: desktop-style workspace.
The S26 Ultra can also move between phone and DeX modes, but it lacks the Fold’s middle tablet-sized state.
That middle state is the Fold’s defining productivity feature.
What to check before buying
Before paying the Fold premium specifically for multitasking, test your actual workflow.
Check your essential apps
Do your email, messaging, office, cloud-storage and business applications support the layouts you need?
Try your most common two-app combination
If your everyday workflow is browser plus email, or document plus messaging, see how comfortably those applications work side by side.
Test three-app workflows
If three-way multitasking is central to your work, make sure the specific applications you use behave properly when the screen is divided.
Decide whether you need DeX
If you regularly have access to a monitor and keyboard, the S26 Ultra’s DeX capability may already cover much of your desktop-style workflow.
Think about what device the Fold replaces
If it can reduce how often you carry a tablet or laptop, its large screen becomes easier to justify.
If it simply adds another large screen to an existing collection of devices, the value proposition changes.
Consider how often you actually multitask
A Fold is most useful when simultaneous visibility is a recurring need, not an occasional novelty.
The Fold is worth it when the screen changes your workflow
The Galaxy Z Fold8 Ultra’s multitasking advantage is real, but it is highly dependent on how you work.
Samsung has built the device around an 8-inch display, Multi Window, app pairs, Now Nudge and DeX. The company specifically describes workflows involving research, spreadsheets, documents, messaging and content creation.
The Galaxy S26 Ultra remains a capable multitasking device. It supports Samsung DeX and can turn into a desktop-style workstation when connected to a compatible display.
The crucial difference is what happens before you reach a desk.
If your work involves repeatedly comparing information, responding to messages while viewing documents, researching while taking notes or managing several applications at once, the Fold8 Ultra’s 8-inch screen can fundamentally reduce the friction of those tasks.
If you mostly switch between apps one at a time, the conventional S26 Ultra may already provide everything you need.
**The Fold is worth considering for multitasking not because it can run more apps, but because it can keep the right apps visible at the same time. That distinction is what determines whether its foldable design becomes a daily productivity tool or simply an expensive larger screen.**
