What is DeX mode and what is desktop mode on Android?

Samsung DeX is a technology exclusive to Galaxy devices. This feature allows you to use your mobile phone or tablet as if it were a desktop computer. Simply connect your device to a monitor, television, or even a compatible PC, and the interface will completely change, adopting an appearance similar to a classic desktop system, with a taskbar, application icons, and windows that can be moved and resized.

DeX has evolved with the different versions of One UI, incorporating wired and wireless connection modes, multi-screen support, taskbar improvements and, on the latest Galaxy tablets, integration with the Google's new desktop mode to organize applications across different workspaces. This convergence brings it closer than ever to a "real" PC.

Desktop mode in pure Android, meanwhile, is a feature of Google's operating system. It aims to offer a DeX-like experience, but natively for any manufacturer that wants to adopt it. Initially introduced as an experimental option in developer settings, it has gradually gained stability and features, especially on devices like recent Pixel phones and some Android tablets.

In this environment, Android behaves like a hybrid operating systemYou still have your mobile apps, but the external display interface shows a desktop with a bottom bar, notification area, and separate windows for each app. Many actions are reminiscent of what you would do on a Windows, Linux, or macOS PC, but with your mobile app ecosystem.

At the same time, Manufacturers like Xiaomi have created their own “PC Mode”Primarily adapted for foldable phones and tablets running MIUI, and others like Motorola, Huawei, or even some smaller brands have developed their own desktop environments that activate when the device is connected to an external monitor. They all share the same goal: to allow your mobile phone to become your primary computer when needed.

Samsung DeX compatible models and types of DeX available

Not all Galaxy phones or tablets can activate DeXCompatibility depends on the hardware (especially the USB-C video output) and the version of One UI. It's worth checking if your device supports DeX, and also which type of DeX it can use.

• Galaxy S smartphonesThe S8, S9, S10, S20, S21, S22, S23, S24, and S25 series. These models offer, depending on the generation, support for wired DeX, wireless DeX with compatible displays, and, in many cases, integration with DeX for PC.
• Galaxy Note smartphonesNote8, Note9, Note10 and Note20. They remain a benchmark for productivity, with full DeX compatibility and, in the more advanced generations, wireless connectivity.
• Foldable Galaxy (Fold and Z Fold): Original Fold, Z Fold2, Z Fold3, Z Fold4, Z Fold5, Z Fold6 and Z Fold7, plus the Z Flip7 family. EyeThe Z Flip7 FE model does not support DeX via HDMI cable or wireless DeX with a TV or monitor, so in this case you can only use other methods such as simple screen mirroring.
• Galaxy A SmartphonesThe A90 5G is the A-series model that officially incorporates DeX compatibility, especially designed for those looking for a good price-performance ratio and also a desktop mode.
• Galaxy Tab Tablets: Tab S4, Tab S5e, Tab Active Pro, Tab S6, Tab S7 series, Tab S8 series, Tab S9 series, Tab S10 series, Tab S11 series and Tab Active 3. Some “FE” or “Lite” models have limitations: for example, Tab S9 FE, Tab S10 Lite, Tab S10 Plus and Tab S10 FE They are not compatible with HDMI output. direct, which restricts how DeX can be used with external displays.

On many of these Galaxy tablets with the latest One UI, activating DeX will give you a combination of Classic DeX (with a desktop and taskbar similar to a PC) and the new desktop mode based on Googlewith features such as separate workspaces or “desktops” to organize apps by context (work, leisure, study…).

In addition, there are several different ways to use DeX:

• Wired DeXConnection via USB-C to HDMI, USB-C to DisplayPort, or through DeX docks or cradles. This is the most stable option with the lowest latency.
• Wireless DeX: connection to Miracast-compatible TVs or monitors or smart displays, without the need for a direct cable between the mobile phone and the monitor.
• DeX for PC: using DeX in a window within a Windows or Mac computer, using the mobile phone as the “CPU” and the PC as the screen/keyboard/mouse.

Essential requirements for using desktop or DeX mode

Not all mobile phones or tablets can activate desktop mode or DeX.Depending on the system chosen (Samsung DeX, pure Android desktop mode, Xiaomi PC mode, or other alternatives), you will need to meet a number of key preconditions:

• compatible deviceFor Samsung DeX, you need one of the compatible Galaxy phones or tablets mentioned earlier. For Android's experimental desktop mode, your device must have at least Android 10, although the experience is much better on newer Android versions and on devices like modern Pixel phones.
• Developer options activeTo force desktop mode on stock Android or some manufacturers' devices, you need to enable developer options. This is done by tapping repeatedly on the [icon/button/tool ​​name]. "Build number" In Settings > About phone, go to Settings until a message appears indicating that you are now a developer.
• USB-C to HDMI adapter or DeX dockA good quality adapter is essential for connecting your device to the external display. For DeX, Samsung sells a specific base and some official docks, but there are more affordable alternatives (starting at €20-30 in online stores) if you only need to mirror or extend your screen.
• Screen or monitor with HDMI inputMost modern TVs and computer monitors include this input. If your monitor only has DisplayPort or DVI, you'll need to use specific adapters.
• Optional peripheralsA mouse, keyboard, or even a USB hub to connect multiple devices. These aren't mandatory, but They greatly improve the experience in any desktop mode.

On Xiaomi models and some other Android devicesYou may be prompted to install a third-party APK (such as PC Launcher or other desktop launchers) to simulate the full experience. Also, don't forget that the adapter quality It is crucial to ensure that the transmission of image and sound is adequate and stable.

It's also worth checking the configuration of your cable or dock: some seemingly identical USB-C cables They do not support video output (data and charging only), so it is always recommended to use cables specifically certified or tested for HDMI/DisplayPort.

How to activate Samsung DeX step by step

Samsung DeX mode stands out for its ease of use and professional appearance.Once you have all the necessary materials, the activation process is very similar to the one Samsung explains in its official documentation, with slight differences depending on the model and version of One UI.

1. Connect the USB-C or HDMI cable Connect the cable to the port on your Samsung phone or tablet. Connect the other end to an available HDMI port on your TV or monitor. If you're using a DeX dock or hub, connect the monitor to the dock first, and then connect the dock to your device.
2. Unlock the deviceIf this is your first time using it, a pop-up window will automatically appear inviting you to start DeX mode. Press the button. "Start" to allow access to full desktop mode.
3. If no pop-up window appearsSwipe down with two fingers to open the quick settings panel and select the icon. DeXOn some models, you'll also find a "Samsung DeX" notification in the top bar; tap it and choose the option to launch the desktop.
4. On certain devicesThe TV or monitor will automatically begin mirroring your mobile phone or tablet screen. To switch specifically to the DeX desktop, open the notification panel and tap the notification. Samsung DeX and select the “Samsung DeX” option instead of just “Screen Mirroring”.
5. If another pop-up window appears on your mobile or tablet (for example, requesting permissions or confirmations), click on "To accept" To continue. Samsung usually shows a brief introduction to DeX the first time you use it.
6. Activate the virtual touchpad By tapping the corresponding icon that appears in the lower left corner of the DeX interface on your mobile phone or tablet, you can use the device's screen as a trackpad to move the pointer on the external monitor.
7. Scroll through the windows in DeX Press and hold the virtual touchpad and drag the pointer up or down. You can tap the information icon for basic supported shortcuts and gestures (some advanced gestures, such as two-finger zoom, may not work on all models).
8. If the TV or monitor displays additional instructions On screen, review them and select "Accept" to finish the initial setup. In some cases, gestures, buttons, and the taskbar layout are explained.
9. To exit DeX, select the icon Applications in the lower left corner of the DeX screen and then choose the option “Leaving DeX”You can also use the corresponding button on the taskbar if it is available.

ImportantIf you disconnect the cable without first exiting DeX, the system may restart the desktop environment, and you could lose unsaved changes to documents or apps. It's always recommended to exit DeX without first exiting. Save your work before unplugging HDMI or USB-C.

On some Galaxy tablets with recent versions of One UI, you'll find a DeX-specific menu in Settings > Connected Devices (often identified by the color orange). From there you can decide what the DeX quick panel button does, for example changing it from “wireless display” to “switch to desktop workspace”This way, you can activate and deactivate DeX directly from the quick panel in a clearer way and take advantage of the enhanced desktop mode even when "classic DeX" is not present.

What can you do in DeX mode?

The Samsung DeX experience goes far beyond screen mirroringIt's an environment designed for work, but also for leisure and advanced multitasking. In this mode you can:

• Working in multiple windows at onceJust like on a real PC. You can resize, move, and organize different applications, pin them to the edges to split the screen, or keep them floating above others.
• Browsing the internet, editing documents, replying to emails, or running presentations with a productivity far superior to that of the usual mobile interface, thanks to the combination of keyboard, mouse and large screen.
• Connect accessories such as keyboard and mousewhether by cable or Bluetooth. This makes the typing and browsing experience much closer to that of a laptop or PC.
• Connect USB flash drives, external hard drives, or even additional monitorsDepending on the dock or hub you use, your phone or tablet can become a true portable workstation.
• Receive and manage real-time notifications directly on the DeX desktop, with quick access to the settings panel and notification area, similar to a computer's system tray.
• Organize apps by tasks or projects, taking advantage of the workspace and app group capabilities in desktop mode on the latest Galaxy tablets.
• Play Android games on a big screenUsing controllers, keyboard and mouse when games allow it, which opens up interesting options for entertainment.

With the evolution of Google's desktop mode and its integration with One UI, DeX also allows group apps into different workspaces (for example, Desktop 1 for work, Desktop 2 for leisure, Desktop 3 for studying…) and switch quickly between them. This significantly improves organization and concentration, especially when working with many windows open.

Desktop mode on Android: activation, features, and real-world experience

Android's pure desktop mode is not as well-known or as polished as DeX.But it also allows you to transform your phone into a makeshift workstation with a desktop interface. On devices like the latest Google Pixel models, this feature is better integrated and offers an experience increasingly similar to that of a PC.

To activate it on compatible mobile devices that still maintain it as an advanced or development feature, the general steps are:

• Enable developer optionsGo to Settings > About phone and tap "Build number" several times until you are told that you are now a developer.
• Go to Settings > System > Developer OptionsWithin this menu, look for the option related to “Desktop features” or “Force desktop mode” and activate it. On some devices it is called “enable desktop features” or similar.
• Reboot the device If the system prompts you after activating desktop mode. This step is usually required for the change to take effect correctly.
• Connect your phone with a USB-C to HDMI adapter to the external display. You can also use a compatible USB-C monitor that receives video directly.
• Select the usage modeOn devices like the Pixel, when the external screen is detected, you'll be offered the option to use the phone as a "Computer" (desktop mode) or simply project the screen. Choose "Computer" or "desktop mode".
• Connect mouse and keyboard via Bluetooth or USB. Using desktop mode without external peripherals is possible, but the experience is much more limited.

Once these steps are completed, the large screen will display a desktop interface with bottom bar and top status barYou'll have an app launcher, a spot to pin your favorite apps, and a notifications and quick settings area.

The experience is surprisingly similar to using a PC: you can open multiple windows, resize them, move them, and organize them However you want. Applications like Chrome, text editors, email, messaging clients, or even file managers work in this environment almost as they would on a traditional computer.

There are, however, important differences: Android has not historically been conceived as a system for "messing around" with files and folders, so the The native file manager is more limited than Windows or Linux, and tasks such as handling large amounts of documents or complex directories can be less intuitive. The command-line interface or terminal also requires third-party apps and is not as integrated as in traditional desktop systems.

Even so, for many use cases (office applications, browsing, email, social networks, multimedia consumption, or even some content creation), Android's desktop mode offers a real alternative to a lightweight PCIf you already regularly work with a laptop, this mode will allow you to replicate part of your workflow using only your mobile phone and an external monitor available at home, in the office, or in a coworking space.

PC mode on Xiaomi and other desktop alternatives on Android

Xiaomi also offers its own desktop mode under the name “PC Mode”This is especially true for foldable devices like the Mi Mix Fold and smartphones and tablets running recent versions of MIUI and stable Android. This mode adapts the interface to a horizontal desktop with a taskbar and floating windows.

• You will need to install the PC Launcher APK (or the specific launcher that Xiaomi uses for PC mode) and grant the corresponding permissions, such as display over other apps or usage access.
• Once the PC mode application is openThe mobile interface will change and adopt a horizontal layout similar to that of a conventional computer, with a desktop, bottom bar and window management.
• You may need to restart your device. to complete the installation and the full interface change, depending on the MIUI version.
• Performance on other Android phones not made by Xiaomi is inconsistent. And it's not guaranteed. Although the APK can be installed, many features depend on specific MIUI layers.

This option is intended for advanced users who want to experiment and get the most out of their mobile phone beyond conventional functions, just like those who try desktop environments from Motorola, Huawei, Honor or other manufacturers.

Besides Xiaomi, other notable alternatives include:

• Motorola Ready For or Desktop ModeSome Motorola models offer a very complete desktop mode, with PC integrationIt allows you to use your phone as a webcam and offers specific modes for gaming, video, or productivity. It's one of the systems closest to DeX in terms of maturity.
• Huawei Desktop Mode (on compatible models): Implements a desktop with windows and taskbar that is activated when the device is connected to a monitor, although availability and support vary by model and region.
• Third-party launchers (like Sentio, Leena Desktop UI and similar): although many are not as active as before, they are still an option for those who want a kind of desktop within the mobile itself, without the need for an external monitor, or a more "PC" interface when connected.

Each manufacturer brings its own approach, but they all share the idea of reuse the power of the mobile in a desktop format when you connect a large screen.

Can I use desktop mode on an iPhone?

On Apple devices the experience is much more limited.iOS and iPadOS allow you to connect your iPhone or iPad to external displays, but the system interface does not transform into a classic desktop with floating windows and a taskbar like DeX or Android's desktop mode.

What you can do is force the desktop version of websites in browsers, which gives you more space and options when working with complex pages:

• Open Safari and access any website you need to view with more features.
• Press the button with the two letters “a” next to the address bar at the top.
• Select “Desktop version”The website will reload, displaying the full interface you would see on a computer.

This is available in recent versions of iOSIn other browsers like Chrome or Firefox for iPhone, the option is usually called "Desktop version" or similar, but the integration with the external screen is still very different from what Android offers: there is no full desktop, but rather a mirrored screen or, at best, a second screen for certain apps.

The desktop version in the browser: an option for everyone

If your mobile device is not compatible with desktop mode or DeXYou can always take advantage of the "Desktop Site" feature within your browser. It doesn't turn your system into a PC environment, but it can significantly improve the usability of some websites.

• Open your favorite browser (Chrome, Firefox, Edge or another similar).
• Press the three-dot menu (usually in the upper right corner) and activate the "Desktop site" or "Computer version" option.

The website will appear with its full interface.It displays the page as you would on a computer, but only for that tab. It's not as versatile a solution as DeX or Android's desktop mode, but it can be a lifesaver if a page is poorly optimized for mobile devices or if you need buttons and menus that only appear in the desktop version.

What is desktop mode really for?

Desktop mode, or DeX, is primarily designed to increase productivity on the go.You can use your tablet or mobile phone connected to an external screen to perform many of the tasks you would normally do with a laptop:

• Office tasksEdit documents, create spreadsheets, prepare presentations, and answer emails more easily, taking advantage of compatibility with suites like Google Workspace, Microsoft 365, or other alternatives.
• Easy internet browsing and professional email management, with multiple tabs open at the same time and windows with different applications related to your work.
• Play on the big screen to compatible titles that support mouse, keyboard or controllers, enjoying a more immersive experience than on the mobile screen.
• Quick information queries or collaborative work by displaying the information in a room, classroom or projector without having to move a laptop.
• Access to native apps such as WhatsApp, Telegram or social media apps, without needing to resort to web versions, since they run directly in the desktop environment.

In addition, it allows you to connect external peripherals. such as mice, keyboards, speakers, or even printers (when the apps allow it), which increases productivity and convenience. The key is that everything you do runs on your own mobile phone or tablet, without depending on the power of an external PC.

Desktop mode in the car: Auto DeX and alternatives

Although most users use DeX or desktop mode on monitors and televisions, It's also possible to bring this experience to the car. Under certain circumstances, some users combine DeX with their vehicle's screens as an advanced alternative to Android Auto, when the car's screen allows it.

The concept of “Auto DeX” is based on take advantage of the wired or wireless connection of the mobile phone to the car's multimedia system To display a desktop with navigation, music, messaging, or productivity apps, instead of the simplified Android Auto interface. This can be useful if your car doesn't have official Android Auto, or if you prefer a more complete interface.

However, it is important to take certain considerations into account:

• The car's screen must accept video input or allow advanced mirroring from your mobile phone, something not all models offer.
• Safety behind the wheel is a priorityManaging a full desktop with windows and apps while driving can be very dangerous. It's best to use it only when the vehicle is stopped or to have a passenger manage it.
• In many cases, Android Auto is more practical. or equivalent systems, as they are designed to minimize distractions and prioritize basic driving functions (navigation, calls, music and voice messages).

Even with these limitations, knowing that desktop mode can also be used in contexts such as in the car expands the range of potential uses, as long as we are aware of the risks and legal restrictions.

Limitations and aspects to take into account

Desktop mode, while useful, is not without its technical and practical limitations.Before opting for it as a complete replacement for your laptop, it's worth knowing its weaknesses:

• Higher battery consumptionConnecting external devices, keeping the screen on, and rendering on a large monitor increases energy consumption. It's recommended to keep your phone charging while using desktop mode, especially for intensive tasks like video editing or gaming.
• Not all applications are optimizedSome apps display like they would on a mobile screen, with narrow columns or oversized elements, or they may even freeze in unusual orientations. Each developer decides how much support to offer for large screens and resizable windows.
• Hardware dependency and Android versionOn older or lower-end models, performance may suffer, with lag, forced closures, or the inability to launch desktop mode. On some devices, Google or the manufacturer may limit or disable desktop mode for performance reasons.
• Limited touch gestures on the virtual touchpadFeatures such as two-finger zoom or some advanced trackpad gestures are not always supported, which slightly reduces the naturalness of the control.
• File management less powerful than on a PCAlthough you can move, copy, and manage documents, Android isn't as geared towards a classic folder structure, and this can limit certain more advanced workflows.

In addition to all this, depending on the version of One UI, MIUI or other layers, There may be significant changes in the behavior of DeX or desktop mode.This includes the disappearance of "classic DeX" on some tablets and its replacement with workspaces based on Google's desktop mode. In these cases, it's worth checking settings like the quick panel button to choose between "wireless display" and "desktop workspace."

When to use desktop mode: practical situations

Beyond pure productivityDesktop mode can help you in many other circumstances:

• Troubleshooting screen problemsIf your mobile phone's screen malfunctions, goes black, or has areas that don't respond to touch, you can try connecting the phone to an external display and controlling it from there with a mouse or the virtual touchpad to restart, back up, or recover important data.
• Presentations and impromptu meetingsWith a simple USB-C to HDMI cable or a compatible adapter, you can turn your mobile phone into the room's computer to display documents, presentations, images, or applications on a large screen, without having to depend on the equipment in the room.

• Always use quality HDMI adapters To avoid interruptions, signal loss, black screens, or poor image and sound transmission. Very cheap adapters are usually less stable and sometimes don't support the resolution or refresh rate you need.
• Save your work before unplugging the cable or exiting DeXBecause you could lose data if the system restarts unexpectedly or if the connection is abruptly interrupted. Treat it as if you were unplugging a laptop cable from a monitor.
• If you experience errors or app crashesUpdate your phone and apps to the latest available version. Many incompatibilities and performance issues are resolved with firmware patches and developer improvements.
• Consider investing in Samsung's official database. If you intend to use DeX regularly at a fixed workstation, generic adapters will work, but official docking stations typically offer better cooling, more ports, and greater connection stability.
• Customize the taskbar and workspaces On Galaxy tablets with advanced desktop mode, you can pin the apps you use most and organize themed desktops (work, leisure, study) for faster access to what you need.
• Connect the monitor first, then the mobile device. In some models, the connection order can affect the correct detection of desktop mode. If the monitor displays nothing, try disconnecting and reconnecting in this order.
