Samsung’s DeX mode, the feature that turns a Galaxy phone into something resembling a desktop computer, has been around since 2017. Eight years. In that time, every major competitor has either abandoned its own version of the idea or never bothered to build one. Apple hasn’t done it. Google flirted with it and walked away. Motorola tried, gave up, tried again with a half-measure. And yet DeX keeps getting better, keeps getting refined, keeps showing up in every new Galaxy flagship and even mid-range devices.
The question isn’t whether DeX is good. It is. The question is why Samsung is still the only company that seems to believe a phone can replace a PC for a meaningful number of people — and whether that belief is finally about to pay off in a bigger way.
Android Police published a detailed analysis this week making the case that DeX remains the clear winner in the phone-to-desktop category, and the argument is hard to dispute on the merits. The piece walks through the competitive field — or what’s left of it — and finds Samsung standing essentially alone with a polished, functional product while everyone else offers compromises, experiments, or nothing at all.
Start with what DeX actually does in 2025. Connect a Galaxy phone to a monitor via USB-C or wirelessly through Miracast, and the phone’s interface transforms into a windowed desktop environment. There’s a taskbar. There are resizable app windows. You get keyboard and mouse support, file management, and multi-monitor capability on newer devices. Samsung has steadily added features over the years: better window snapping, improved external display handling, and tighter integration with Samsung’s own apps. It’s not Windows. But it’s not trying to be. For email, web browsing, document editing, video calls, and light productivity, it works remarkably well.
The hardware requirements are minimal. A USB-C to HDMI cable or a compatible dock. A Bluetooth keyboard and mouse. That’s it. Samsung doesn’t even sell a dedicated DeX dock anymore — the original DeX Station was discontinued years ago — because the feature has been refined to the point where generic USB-C hubs work fine.
So where is the competition?
Motorola’s Ready For, launched in 2021 with some fanfare, was the most visible challenger. It offered a desktop-like mode when connected to an external display, along with a dedicated mobile interface for gaming and video. But Motorola never committed the engineering resources to make it competitive. App compatibility was inconsistent. The interface felt unfinished. And as Android Police noted, Motorola has effectively deprioritized the feature, with recent devices offering only basic external display mirroring rather than a true desktop transformation. Ready For isn’t officially dead, but it’s on life support.
Google’s approach has been characteristically noncommittal. Android 13 introduced basic desktop windowing capabilities for external displays, and Android 14 expanded on them slightly. Android 15 brought further refinements to freeform windowing. But Google has treated this as a platform-level capability for OEMs to build on rather than a consumer-facing feature with its own branding and polish. The Pixel phones support external display output, but the experience is rudimentary compared to DeX. No taskbar. No system tray. Limited window management. It feels like a developer preview, not a finished product.
There have been persistent rumors that Google is working on a more complete desktop mode for Android, potentially tied to its broader push into tablets and foldables. But rumors don’t ship products. And Google’s track record of launching and then abandoning features — remember Google Desktop? Android tablets the first time around? — gives little reason for confidence.
Apple, meanwhile, has gone in a completely different direction. Stage Manager on iPad offers some desktop-like multitasking, and the company has invested heavily in making the iPad a productivity device. But the iPhone? Nothing. Apple has shown zero public interest in letting an iPhone drive a desktop display. The company’s incentive structure works against it — why would Apple cannibalize Mac sales by making the iPhone a computer replacement? Tim Cook’s Apple sells you a phone, a tablet, a laptop, and a desktop. Four devices, four revenue streams. Letting the phone do the laptop’s job undermines the whole model.
This is what makes Samsung’s persistence with DeX so interesting from a strategic perspective. Samsung doesn’t sell its own desktop operating system. It doesn’t have a MacBook competitor in the traditional sense. Its laptop business runs Windows, which Microsoft controls. DeX gives Samsung something Apple and Google already have through other products — a desktop computing story — using only hardware Samsung fully controls: the phone.
The business case has also shifted. When DeX launched in 2017, it was positioned primarily as a consumer convenience. Now Samsung markets it aggressively to enterprises. A company can issue employees Galaxy phones that double as desktop workstations when docked at the office. One device to manage, one device to secure, one device to replace. IT departments that have piloted DeX deployments report meaningful savings on hardware procurement and device management overhead. Samsung’s Knox security platform wraps around the entire experience, giving administrators control over what apps and data are accessible in DeX mode versus standard phone mode.
The enterprise angle matters because it provides a financial justification for Samsung to keep investing in DeX even if consumer adoption remains modest. Corporate contracts are worth far more per unit than individual phone sales, and DeX serves as a genuine differentiator when Samsung is competing against Apple and Pixel for enterprise deals.
But the consumer side shouldn’t be dismissed either. The rise of cloud-based productivity tools — Google Workspace, Microsoft 365, Slack, Notion, Figma — means more people can do more of their work in a web browser or a cross-platform app. The bottleneck used to be software compatibility: desktop applications simply didn’t exist on Android. That bottleneck has narrowed considerably. Not disappeared. Narrowed. Professional video editing, software development, and CAD work still require traditional desktops. But the percentage of knowledge workers whose daily tasks could theoretically be handled by a phone connected to a monitor keeps growing.
There’s a demographic dimension too. In many markets outside the United States and Western Europe, smartphones are the primary — sometimes only — computing device people own. A feature that turns a $400 Galaxy A-series phone into a functional desktop computer isn’t a novelty in those markets. It’s access. Samsung has recognized this and made DeX available on mid-range devices, not just flagships. That decision alone separates Samsung’s approach from the premium-only strategies of its competitors.
Recent developments in the broader Android world add context. Google’s work on Android’s desktop windowing capabilities, while incomplete, suggests the company sees external display use as a growth area for the platform. The Android 15 release included improvements to freeform window behavior and better support for keyboard shortcuts — foundational elements that benefit DeX even if Google’s own implementation lags behind. Samsung has historically taken Google’s base Android capabilities and built more polished experiences on top of them, and desktop mode is no different.
The foldable phone trend also plays into DeX’s relevance. Samsung’s Galaxy Z Fold series already offers a tablet-sized inner display that supports split-screen and multi-window multitasking. Connecting a Fold to an external monitor via DeX essentially creates a three-screen setup: the phone’s cover display, the inner foldable display, and the external monitor. It’s excessive for most people. But for the power users and mobile professionals Samsung is targeting, it represents a level of flexibility no other phone manufacturer matches.
Critics of DeX tend to focus on two things: app optimization and performance. Most Android apps are still designed for phone-sized screens, and while DeX can run them in resizable windows, many look awkward or waste screen space on a 27-inch monitor. This is a real limitation. Samsung can’t force every Android developer to optimize for desktop-sized windows, and Google’s own efforts to encourage large-screen app development have produced mixed results. The apps that work best in DeX — Samsung’s own apps, Microsoft Office, Google’s productivity suite, web browsers — cover a lot of ground but not all of it.
Performance is the other concern. A phone’s processor, no matter how capable, isn’t a laptop chip. The Snapdragon 8 Elite in the Galaxy S25 Ultra is fast, but running multiple windowed apps on a large display while simultaneously handling phone functions pushes the hardware. Thermal throttling can occur during extended sessions. Storage I/O is slower than a dedicated SSD in a laptop. These are physics problems, not software problems, and they impose a ceiling on what DeX can do.
And yet.
For the tasks most people actually perform on a computer — email, documents, spreadsheets, web browsing, video conferencing, messaging — DeX is more than adequate. It has been for at least two or three hardware generations. The gap between what DeX can do and what a $500 Chromebook can do has shrunk to the point where, for many users, the difference is academic.
Samsung’s challenge now isn’t technical. It’s awareness. Most Galaxy phone owners don’t know DeX exists. Samsung buries it in settings rather than surfacing it during phone setup. The company runs occasional marketing campaigns around the feature but has never given it the kind of sustained push it gives to cameras or AI features. If you asked a hundred Galaxy S25 owners whether their phone could become a desktop computer, the majority would probably say no.
This is the paradox of DeX in 2025. It’s the best version of phone-as-desktop computing anyone has built. It has no serious competitors. It serves real needs for real users. And it remains one of the most underappreciated features in consumer technology.
Whether that changes depends less on Samsung’s engineering — which has been consistently strong — and more on whether the company decides DeX deserves a starring role rather than a supporting one. The product is ready. The market conditions are favorable. The competition is absent. All that’s missing is the conviction to bet bigger.
Samsung has spent eight years building something nobody else would. The question now is whether it has the nerve to tell people about it.
