Samsung DeX for Business: The Complete UK Guide to Using Your Phone as a Laptop

Last updated: April 2026

Most UK businesses are still buying separate laptops, desktops, and phones for every employee. For many roles, that is an unnecessary expense. Samsung DeX turns a compatible Samsung phone into a full desktop computer experience, complete with resizable windows, a taskbar, keyboard and mouse support, and access to the same apps your team already uses. One device. Two modes. Potentially thousands of pounds saved across a fleet.

As an OFCOM-regulated comparison service with a 4.3/5 Trustpilot rating, we have been helping UK businesses choose the right mobile technology since 2008. As a Samsung partner, we have seen first hand how DeX is changing the way businesses think about hardware. This guide covers everything you need to know about Samsung DeX for business: what it is, how it works, which devices support it, what it can and cannot do, and whether it makes financial sense for your organisation.

What Is Samsung DeX?

Samsung DeX (short for Desktop Experience) is a feature built into Samsung's Galaxy smartphones and tablets that transforms the Android mobile interface into a full desktop computing environment. When you connect a compatible Samsung phone to an external monitor, either through a USB-C cable or wirelessly, the phone's display changes from a mobile layout to a desktop layout. You get a taskbar along the bottom, resizable application windows, right-click context menus, drag and drop file management, and full keyboard and mouse support.

It is not screen mirroring. When DeX activates, the phone generates a completely separate desktop interface on the external display while the phone screen continues to function independently. You can take a call or reply to a WhatsApp message on the phone while working in a spreadsheet on the monitor. Two screens, two interfaces, one device.

Samsung first introduced DeX in 2017, and it has matured significantly since then. In 2026, DeX is a polished, stable platform that genuinely works as a desktop replacement for a wide range of business tasks. It is not a gimmick or a tech demo. It is a production-ready tool that thousands of businesses worldwide already rely on daily.

How Samsung DeX Works

Wired Connection (USB-C to HDMI)

The simplest way to use DeX is with a USB-C to HDMI cable or adapter. You plug the USB-C end into your Samsung phone and the HDMI end into any monitor, television, or projector. DeX launches automatically. Plug in a USB keyboard and mouse (either directly into a USB-C hub or via Bluetooth), and you have a complete workstation.

The wired connection provides the best performance: zero latency, full resolution support (up to 4K on supported devices), and a stable connection that will not drop. For fixed workstations where an employee sits at the same desk each day, wired DeX is the recommended approach.

Wireless DeX (Miracast or Smart TV)

DeX also works wirelessly on any Miracast-compatible display or Samsung Smart TV. You simply swipe down on the phone's notification panel, tap the DeX icon, and select the target display. No cables, no adapters. Within seconds, the desktop environment appears on the external screen.

Wireless DeX is ideal for meeting rooms and presentation scenarios where you want to walk in, connect, and present without fumbling with cables. The trade-off is a slight increase in latency compared to wired mode, which is barely noticeable for presentations and document work but can be felt in fast-scrolling or video playback.

DeX on a Laptop (Windows or Mac)

Samsung also offers a DeX app for Windows PCs and Macs. With this, you connect your phone to a laptop via USB-C, and DeX opens as a window on the laptop's desktop. You can drag and drop files between the laptop and the phone, use the laptop's keyboard and trackpad to control the phone, and run phone apps alongside laptop apps. This is particularly useful for transferring files or accessing phone-only apps from a larger screen.

The Desktop Environment

Once DeX is active, the experience feels remarkably close to a traditional PC:

Taskbar: A persistent bar at the bottom of the screen shows running apps, pinned favourites, the system tray, and the clock. It functions just like the Windows taskbar.
Resizable windows: Every app opens in its own window that you can resize, minimise, maximise, snap to the left or right half of the screen, or drag anywhere on the desktop.
Right-click menus: Connect a mouse and you get full right-click context menus throughout the interface.
Keyboard shortcuts: Standard shortcuts work as expected. Ctrl+C, Ctrl+V, Alt+Tab, and others function just as they would on a PC.
File manager: Samsung's My Files app provides a desktop-class file browser with folder navigation, search, and network drive access.
Multi-monitor awareness: Some newer devices support extended display across two monitors, though this is still evolving.

Business Use Cases for Samsung DeX

Hot-Desking Without PCs

This is the use case that gets the most attention, and for good reason. In a hot-desking environment, employees do not have assigned workstations. They arrive, find a free desk, and start working. Traditionally, this requires either a pool of shared laptops (with all the security and hygiene concerns that entails) or a virtual desktop infrastructure (VDI) that is expensive to set up and maintain.

With DeX, every desk needs only a monitor, a keyboard, a mouse, and a USB-C hub. The employee arrives, plugs in their Samsung phone, and instantly has their personal desktop environment: their apps, their files, their email, their browser history. When they leave, they unplug and take everything with them. No shared hardware. No VDI licensing fees. No IT setup required at each workstation.

Reducing Hardware Costs

For roles that do not require heavy computing power, DeX can replace a desktop PC entirely. Consider how many employees in a typical business spend their working day in a web browser, Microsoft Office, email, and perhaps a CRM or accounting package. Reception staff, call handlers, basic admin roles, booking coordinators, customer service agents. These roles do not need a dedicated PC with a discrete graphics card and 16 GB of RAM. A Samsung phone running DeX handles all of these tasks comfortably.

The cost saving is significant. Instead of buying a phone and a desktop (or laptop) for each employee, you buy one device. We break down the specific numbers later in this guide.

Field-to-Office Flexibility

Field workers, surveyors, sales representatives, and engineers often need a phone on site and a computer back at the office. With DeX, one device covers both scenarios. An electrician uses the phone to photograph a job, access wiring diagrams, and log time on site. Back at the depot, they plug the same phone into a monitor and complete paperwork, raise invoices, and file reports from a full desktop interface. No syncing. No transferring files between devices. Everything lives on one device.

Presentations and Meeting Rooms

Walk into any meeting room with a screen or projector. Connect wirelessly via DeX. Present a slide deck, demonstrate a product, walk through a spreadsheet, or show a website. No laptop required. No hunting for the right dongle. No worrying about whether the meeting room PC has your files on it.

For businesses with multiple meeting rooms, DeX eliminates the need for a dedicated presentation PC in each room. Just a screen and a wireless connection is all you need.

Temporary and Pop-Up Workstations

Businesses that set up temporary workstations at events, trade shows, construction site offices, or seasonal locations benefit enormously from DeX. Instead of transporting laptops and worrying about theft, damage, or setup, you send staff with their Samsung phones and a few inexpensive monitors. Full workstations in minutes, packed down in seconds.

Business Continuity and Disaster Recovery

If your office suffers a flood, fire, or power outage, your employees still have their Samsung phones. With DeX, they can set up a complete working environment at any location with a monitor: a co-working space, a hotel business centre, a colleague's home. Your data, apps, and workflows travel with the device. There is no dependency on office-based hardware.

Compatible Samsung Devices

DeX is available on a wide range of Samsung Galaxy devices. As of April 2026, the following current-generation devices support DeX:

Flagship Phones

Samsung Galaxy S26 Ultra — the most powerful DeX experience, with the Snapdragon 8 Elite 2 processor, 12 GB RAM, and support for up to 4K output. Ideal for power users and senior staff.
Samsung Galaxy S26+ — same DeX capability in a slightly smaller form factor. Excellent for most business roles.
Samsung Galaxy S26 — full DeX support with flagship performance. The best balance of price and capability for business fleets.

Foldable Phones

Samsung Galaxy Z Fold7 — a particularly strong DeX device because of its large inner display. You can use DeX on an external monitor while using the unfolded phone as a secondary screen or trackpad. See our full guide to the Galaxy Z Fold7 for business.
Samsung Galaxy Z Flip7 — supports DeX, though the smaller battery and compact form factor make it better suited for occasional rather than prolonged DeX use.

A-Series (Mid-Range)

Samsung Galaxy A56 — DeX support with mid-range performance. For businesses deploying large fleets where not every role needs flagship power, the A-series offers DeX at a substantially lower cost per device.
Samsung Galaxy A36 — entry-level DeX support. Suitable for basic desktop tasks like email, web browsing, and simple document editing.

Tablets

Samsung Galaxy Tab S10 series — DeX on a tablet is particularly compelling. The tablet itself can serve as the monitor (with a keyboard case), or it can output DeX to an external display. For employees who need a larger portable screen without carrying a laptop, a Galaxy Tab with DeX and a keyboard cover is an excellent alternative.

Essential Accessories for DeX

Getting set up with DeX requires minimal additional hardware. Here is what you need.

USB-C to HDMI Cable or Adapter

The most basic requirement for wired DeX. A simple USB-C to HDMI cable costs between £10 and £20 and is all you need to connect your phone to a monitor. Look for a cable that supports 4K output if your monitor supports it.

USB-C Hub or Docking Station

For a more complete workstation setup, a USB-C hub adds HDMI output, USB-A ports (for keyboard and mouse), an Ethernet port (for wired internet), and a USB-C power pass-through (so your phone charges while in DeX mode). A good hub costs between £30 and £60. Premium docking stations with multiple display outputs and SD card readers are available for £80 to £150 but are overkill for most business DeX setups.

Samsung DeX Station or DeX Pad (Legacy)

Samsung previously sold dedicated DeX docking stations. These are no longer manufactured but still work if you have them. A standard USB-C hub does the same job and is more versatile, so there is no reason to seek out the original DeX Station specifically.

Bluetooth Keyboard and Mouse

Any standard Bluetooth keyboard and mouse works with DeX. Samsung's own Smart Keyboard Trio 500 is compact and designed for DeX, but any brand will work. For businesses deploying multiple DeX workstations, bulk-purchasing affordable Bluetooth peripherals keeps costs low. Expect to pay £20 to £40 for a decent keyboard and mouse combo.

Monitor

Any monitor with an HDMI input works with DeX. You do not need a special Samsung monitor or a touchscreen display. For businesses setting up dedicated DeX workstations, a basic 24-inch Full HD monitor costs £100 to £150. If you already have monitors from retired PCs, they will work perfectly with DeX.

Wireless Display Adapter

If your meeting room screen does not have built-in Miracast support, a wireless display adapter (such as a Microsoft Wireless Display Adapter or similar) adds wireless DeX capability for around £40 to £60.

Apps That Work Well in DeX Mode

One of the most common questions about DeX is whether business apps actually work properly in desktop mode. The answer, for the vast majority of business applications, is yes.

Productivity Suites

Microsoft Office 365 (Word, Excel, PowerPoint, Outlook): Fully optimised for DeX. These apps detect DeX mode and automatically switch to a desktop-style interface with ribbon toolbars, full formatting options, and multi-window support. This is the same experience you would have on a Windows PC for most everyday tasks.
Google Workspace (Docs, Sheets, Slides, Gmail): Works well through both the Chrome browser and the dedicated Android apps. The browser versions provide the most complete desktop experience in DeX mode.
Samsung Notes: Optimised for DeX with a desktop layout. Particularly useful with S Pen-compatible devices.

Communication and Collaboration

Microsoft Teams: Fully functional in DeX mode, including video calls, screen sharing, chat, and file collaboration. Video conferencing works using the phone's camera and microphone, or you can connect external peripherals.
Zoom: Works in DeX mode for meetings, webinars, and screen sharing.
Slack: Fully functional with desktop-style navigation and multi-window support.
WhatsApp Business: Works in DeX for managing business messaging from a larger screen.

Business Applications

Salesforce: The Salesforce mobile app works in DeX, and the full web version runs well in Chrome in DeX mode. For CRM access, DeX is a perfectly viable alternative to a laptop.
Xero and QuickBooks: Cloud-based accounting packages run smoothly in Chrome through DeX.
HubSpot, Pipedrive, Monday.com: All accessible through Chrome in DeX mode with full functionality.
SAP Business One: The web client works through Chrome in DeX for basic transactions and reporting.

Web Browsers

Samsung Internet and Google Chrome: Both provide full desktop-class browsing in DeX mode. Chrome in DeX mode requests the desktop version of websites by default, so you get the full site rather than the mobile version. Extensions work in Samsung Internet. Tabbed browsing, bookmarks, developer tools, and all standard browser features are available.

Remote Desktop

Microsoft Remote Desktop, Citrix Workspace, VMware Horizon: If you have applications that must run on a Windows server or virtual desktop, you can access them through remote desktop clients in DeX. This extends DeX's usefulness to cover legacy Windows applications that have no Android equivalent.

What DeX Cannot Do: Honest Limitations

Samsung DeX is impressive, but it is not a replacement for every PC in your business. Being honest about its limitations helps you deploy it in the right roles and avoid frustration.

Heavy Computing Tasks

DeX is powered by a smartphone processor. While modern mobile chips are remarkably capable, they cannot match a dedicated desktop CPU and GPU for intensive workloads. Tasks that push beyond DeX's comfortable limits include:

Video editing: Basic trimming and simple edits work, but professional video editing with multiple layers, effects, and 4K rendering is not practical.
CAD and 3D modelling: AutoCAD, SolidWorks, and similar engineering software require dedicated desktop hardware. DeX is not suitable for these workloads.
Software development: While you can do light coding in DeX, running IDEs, compilers, and local development environments is impractical compared to a proper development machine.
Large dataset analysis: Crunching massive spreadsheets with tens of thousands of rows and complex formulas will slow down in DeX compared to a desktop with dedicated RAM and processing power.

Application Compatibility

While most major business apps work well in DeX, some niche or industry-specific applications may not be optimised for the desktop layout. A small number of Android apps stubbornly remain in a phone-sized window even in DeX mode, which is usable but not ideal on a large monitor. This is becoming less common as more developers optimise for large screens, but it is worth testing any critical business applications before committing to a DeX deployment.

Peripheral Support

Most USB peripherals work with DeX through a hub: keyboards, mice, USB drives, printers (with appropriate drivers). However, specialised hardware like barcode scanners, receipt printers, or custom USB devices may require testing to confirm compatibility. Bluetooth peripherals generally work without issues.

Multi-Monitor Support

While DeX supports external display output, true multi-monitor support (extending across two or more external displays) is limited to select newer devices and is still maturing. For roles that depend on multiple screens, a traditional PC setup remains the better choice for now.

Offline Capability

DeX itself works offline, but many of the cloud-based apps that make DeX most useful (Office 365, Google Workspace, Salesforce) require an internet connection. If your employees work in locations with unreliable connectivity, ensure that the apps they need have adequate offline functionality.

Cost Savings Analysis: DeX vs Traditional Desktop Setup

This is where DeX gets genuinely exciting for finance directors and operations managers. Let us work through the numbers for a realistic UK business scenario.

Traditional Setup: Phone + Desktop PC

For a standard office role (admin, reception, customer service, basic data entry), a typical hardware allocation might look like this:

| Item | Estimated Cost | |---|---| | Samsung Galaxy S26 (business contract handset) | £0 to £10/month on contract | | Desktop PC (entry-level business spec) | £400 to £600 | | Monitor, keyboard, mouse | £150 to £200 | | Windows licence (if not included) | £100 to £150 | | PC setup and maintenance (IT time, per device) | £100 to £200/year | | Total hardware cost per employee | £750 to £1,150 upfront + ongoing |

DeX Setup: Phone Only

| Item | Estimated Cost | |---|---| | Samsung Galaxy S26 (same business contract) | £0 to £10/month on contract | | USB-C hub/docking station | £30 to £60 | | Monitor (reuse existing or buy new) | £0 to £150 | | Bluetooth keyboard and mouse | £20 to £40 | | Total hardware cost per employee | £50 to £250 upfront |

The Savings

For a business with 20 employees in roles suitable for DeX (not every role will be, and we have been clear about that), the hardware saving alone could be between £10,000 and £18,000 when replacing desktop PCs. Add the ongoing savings from reduced IT maintenance (no PC updates, no desktop antivirus management, no Windows patches to manage) and the total cost of ownership drops further.

Over a three-year hardware cycle, a 20-person DeX deployment could save £15,000 to £25,000 compared to a traditional phone-plus-PC setup. For larger organisations, the numbers scale proportionally.

There are also softer savings that are harder to quantify but very real: reduced desk space (no PC tower), lower electricity consumption (a phone uses a fraction of the power of a desktop PC), simplified IT inventory, and faster provisioning of new employees (hand them a phone, plug it in, and they are working).

Security: Samsung Knox in DeX Mode

One of the most important questions for any IT manager evaluating DeX is whether it compromises security. The answer is that DeX inherits all of the security protections that Samsung Knox provides on the phone itself.

Knox Protection in DeX

When your phone enters DeX mode, it does not bypass or weaken any security features. Everything that Knox protects on the phone is equally protected in desktop mode:

Knox Vault: Hardware-isolated storage for biometric data, encryption keys, and credentials remains fully active and protected.
Real-time Kernel Protection: Continues to monitor the Android kernel for tampering.
Secure Folder: If your business uses Knox Secure Folder to separate work and personal data, the separation is maintained in DeX mode. Work apps and data stay in the work container.
Device encryption: All data remains encrypted at rest, whether the phone is in mobile mode or DeX mode.

MDM Control Over DeX

If you manage your Samsung fleet through an MDM solution (Microsoft Intune, Knox Manage, VMware Workspace ONE), your policies extend to DeX mode automatically. You can:

Control which apps are available in DeX mode
Restrict USB storage access when in DeX mode
Enforce screen lock policies when the phone is disconnected from the monitor
Remotely wipe the device, which also wipes the DeX environment
Monitor compliance status regardless of whether the device is in phone or desktop mode

BYOD and DeX

For businesses operating a Bring Your Own Device policy, Knox's work container becomes even more valuable with DeX. An employee can use their personal Samsung phone in DeX mode for work, with all business apps and data securely isolated in the Knox work container. When they disconnect from the monitor, their personal apps and data remain completely separate. The employer cannot see personal data. The employee cannot accidentally mix work files with personal files.

Network Security

In DeX mode, the phone uses whatever network connection is available: Wi-Fi, mobile data, or wired Ethernet through a USB-C hub. All existing VPN configurations and network policies apply in DeX mode, so your data travels through the same secure tunnels it would on a laptop or PC.

Apple Has No Equivalent Feature

It is worth stating clearly: Apple does not offer anything comparable to Samsung DeX. You cannot connect an iPhone to a monitor and use it as a desktop computer. Apple's approach is to sell you separate devices for separate use cases: an iPhone for mobile, an iPad for tablet computing, and a Mac for desktop work. Each device is excellent, but each is also a separate purchase.

Apple's Stage Manager on iPad brings some multi-window and external display functionality to the iPad Pro and iPad Air, but it is not available on any iPhone. Even on iPad, Stage Manager does not match the full desktop experience that DeX provides on a Samsung phone. You cannot use an iPad in Stage Manager mode as a true PC replacement in the way that DeX turns a phone into a workstation.

For businesses evaluating iPhone vs Samsung, this is a meaningful differentiator. If reducing hardware costs and simplifying device management are priorities, DeX gives Samsung a capability that Apple simply does not match. For a detailed comparison, see our full guide on iPhone vs Samsung for business in 2026.

How to Set Up Samsung DeX: Step by Step

Setting up DeX is straightforward. Here is the process for both wired and wireless connections.

Wired DeX Setup

Check your phone supports DeX. Any Galaxy S series from S8 onwards, Z Fold series, Z Flip series, A5x series (A52 and above), and Galaxy Tab S series support DeX. If you have a recent Samsung business phone, it almost certainly supports DeX.
Get a USB-C to HDMI cable or USB-C hub. A simple cable works for basic setups. A hub adds USB ports for wired peripherals and Ethernet.
Connect the USB-C cable to your Samsung phone.
Connect the HDMI cable to your monitor and switch the monitor to the correct HDMI input.
DeX will launch automatically. A prompt may appear on your phone asking whether you want to use DeX mode or screen mirroring. Select DeX.
Connect a keyboard and mouse. Plug them into the USB-C hub (USB-A) or pair them via Bluetooth through the phone's settings.
Start working. Your apps, files, and settings are all available in the desktop environment. Pin frequently used apps to the taskbar for quick access.

Wireless DeX Setup

Ensure your display supports Miracast or is a Samsung Smart TV manufactured in 2019 or later.
On your Samsung phone, swipe down from the top of the screen to open the Quick Settings panel.
Tap the DeX icon. If you do not see it, tap the pencil/edit icon to add DeX to your Quick Settings.
Select your display from the list of available wireless displays.
DeX will launch on the external screen. Your phone screen remains independent, acting as a touchpad by default.
Connect a Bluetooth keyboard and mouse for the best experience, or use the phone screen as a touchpad.

Optimising DeX for Business Use

Pin your most-used apps to the taskbar: Outlook, Chrome, Teams, your CRM, file manager.
Set Chrome to request desktop sites by default: Go to Chrome Settings in DeX mode and ensure "Desktop site" is enabled.
Enable screen timeout settings: In DeX settings, configure the screen timeout to suit your work patterns. A longer timeout prevents the display from sleeping during reading or meetings.
Configure Samsung Internet as a secondary browser: Some web apps work better in Samsung Internet than Chrome. Having both available gives you flexibility.
Use keyboard shortcuts: Alt+Tab to switch apps, Ctrl+N for new windows, Ctrl+W to close tabs. Standard shortcuts work throughout DeX.

Samsung DeX for Different Industries

Professional Services (Legal, Accounting, Consulting)

Staff in these sectors spend most of their time in email, document editing, CRM systems, and web-based practice management software. DeX handles all of these tasks comfortably. Partners and senior staff who travel between offices or client sites benefit from having one device that works as a phone on the move and a desktop in the office.

Retail and Hospitality

Store managers and back-office staff can use DeX at the office for scheduling, ordering, and reporting, then pocket the phone and walk the shop floor. In hospitality, front desk staff can run booking and property management systems through DeX during their shift.

Construction and Field Services

Engineers and project managers use the phone on site for photos, measurements, and communication, then plug into a monitor at the site office for plans, documentation, and reporting. The Galaxy S26 Ultra with its S Pen is particularly useful for annotating plans and signing documents.

Healthcare

Administrative and reception staff in GP surgeries, dental practices, and clinics can use DeX for appointment management, patient communication, and basic admin, with Knox ensuring patient data remains encrypted and secure. Clinical systems that run through web browsers work well in DeX mode.

Education

School office staff and administrators can use DeX for attendance systems, parent communication, timetabling, and general admin. Teachers can connect wirelessly to classroom displays for presentations.

Frequently Asked Questions

Can Samsung DeX completely replace a desktop PC?

For roles focused on email, web browsing, document editing, CRM access, and general office administration, yes. DeX provides a genuine desktop experience with resizable windows, keyboard and mouse support, and full versions of Office 365 and other business applications. It is not suitable for roles that require heavy computing power, such as video editing, CAD, software development, or processing very large datasets. For the majority of admin and customer-facing roles in a typical UK business, DeX is a capable replacement.

Which Samsung phones support DeX?

All current Galaxy S series phones (S26, S26+, S26 Ultra), Galaxy Z Fold7, Galaxy Z Flip7, Galaxy A56, Galaxy A36, and Galaxy Tab S10 series support DeX. The feature has been available on Samsung flagships since the Galaxy S8 in 2017. Generally, any Samsung phone from the last few years with a mid-range or flagship processor supports DeX. Check Samsung's official compatibility list if you are unsure about a specific model.

Is Samsung DeX secure enough for business use?

Yes. DeX inherits all security protections from Samsung Knox, which is certified by GCHQ's National Cyber Security Centre and numerous other government security agencies. Knox Vault, real-time kernel protection, device encryption, and MDM policy enforcement all remain fully active in DeX mode. If your Samsung phones are already approved for business use, DeX does not introduce any additional security risk.

What accessories do I need for Samsung DeX?

At a minimum, you need a USB-C to HDMI cable (£10 to £20) and a monitor with an HDMI input. For a comfortable workstation experience, add a USB-C hub with power pass-through (£30 to £60) and a Bluetooth keyboard and mouse (£20 to £40). Total accessory cost for a complete DeX workstation is typically £60 to £120, assuming you already have a monitor.

Does Apple offer anything similar to Samsung DeX?

No. Apple does not provide a desktop mode for iPhones. You cannot connect an iPhone to a monitor and use it as a PC. Apple's Stage Manager on iPad Pro and iPad Air offers some multi-window and external display functionality, but it is not available on any iPhone and does not match the full desktop experience that DeX provides. For businesses that want to use a phone as a desktop replacement, DeX is a Samsung-exclusive capability.

How much can a business save by using DeX instead of desktop PCs?

For a 20-person business replacing desktop PCs with DeX workstations (in suitable roles), hardware savings alone are typically £10,000 to £18,000. Over a three-year hardware cycle, including reduced IT maintenance and support costs, total savings can reach £15,000 to £25,000. Savings scale proportionally for larger organisations. The key is identifying which roles genuinely need a full PC and which can work effectively through DeX.
