Samsung's DeX feature has been quietly transforming smartphones into desktop-like computing experiences since 2017, yet remains one of the company's most underutilized innovations. As powerful smartphones like the Galaxy S25 Ultra continue to blur the lines between mobile and desktop computing, it's worth exploring whether this premium device can truly replace a traditional laptop for everyday tasks.
The Hidden Potential of Samsung DeX
Samsung DeX transforms compatible Galaxy devices into desktop-like workstations when connected to external displays. Despite being available since 2017, DeX remains relatively unknown to most users outside the power-user community. The feature has evolved significantly, now offering wireless connectivity options and enhanced multitasking capabilities that make it increasingly viable as a computing platform. When paired with the processing power of the Galaxy S25 Ultra's Snapdragon 8 Elite for Galaxy chip, which reportedly crushes its predecessor in performance tests, DeX creates a surprisingly capable workstation experience.

Setting Up Your Mobile Workstation
Getting started with DeX is straightforward for owners of compatible Samsung devices, which include recent Galaxy S and Note series phones. Users can connect their phone to a monitor or TV using a USB-C to HDMI cable for the most responsive experience, or pair wirelessly with compatible displays. For a more complete setup, connecting a Bluetooth keyboard and mouse transforms the experience into something remarkably similar to a traditional desktop environment. The phone's display can even function as a trackpad in a pinch, though the lack of haptic feedback makes this less intuitive than a dedicated pointing device.

The Desktop Experience on a Phone
The DeX interface borrows familiar elements from desktop operating systems like Windows, including window snapping, taskbar navigation, and desktop shortcuts. This design choice significantly reduces the learning curve for new users. However, the mobile origins of DeX become apparent when launching applications. While some apps like Google Chrome and YouTube automatically adapt to the desktop environment with expanded interfaces, many others—including popular productivity tools like Slack and social media apps like Instagram—retain their mobile-oriented layouts, appearing as phone-shaped windows on the larger display. Despite these visual inconsistencies, the functionality remains intact, allowing users to access their complete app ecosystem without touching their phone.
Real-World Productivity Test
When put to the test with typical productivity tasks like writing articles, responding to emails, researching topics, and basic photo and video editing, the Galaxy S25 Ultra with DeX proved surprisingly capable. Web-based content management systems, email clients, and even creative applications like Adobe Premiere Rush and Lightroom functioned well enough to maintain productivity. The experience does come with compromises—desktop-specific plugins and extensions aren't available, and specialized software may lack mobile equivalents or offer reduced functionality. However, for users whose workflows center around mainstream applications and services from companies like Google, Microsoft, and Adobe, DeX offers a viable computing alternative.
Unexpected Benefits of Phone-Powered Computing
Working directly from a smartphone through DeX revealed several advantages over traditional computing setups. Notifications remain synchronized across personal and professional applications, eliminating the need to switch between devices to stay updated. The seamless access to the phone's gallery makes transferring photos and videos captured on the device exceptionally convenient—particularly valuable for content creators who frequently use their phones for media capture. Perhaps most surprisingly, the Galaxy S25 Ultra's high-quality front-facing camera serves as an instant webcam upgrade for video calls, though users will need to accept the vertical framing inherent to smartphone cameras.
Value Proposition and Current Offers
For those interested in exploring this desktop-mobile hybrid experience, the Galaxy S25 Ultra is currently available with significant discounts. Amazon offers the 512GB model in Whitesilver at USD $1,170, representing a USD $258 reduction from its original USD $1,420 price point. Even deeper discounts are available directly from Samsung with eligible trade-ins, potentially reducing the price by up to USD $630. While still a premium investment, these discounts make the versatile device more accessible to those seeking to consolidate their computing needs.
The Verdict: Viable Alternative with Limitations
Samsung DeX on the Galaxy S25 Ultra represents a compelling option for users looking to simplify their tech ecosystem by consolidating computing tasks onto a single powerful device. The experience works best for those whose computing needs center around mainstream applications and services, with the understanding that specialized software and desktop-specific features may not be available. While it may not completely replace a laptop for power users with specific software requirements, the convenience of carrying a single device that can transform into different computing experiences depending on the context makes the Galaxy S25 Ultra with DeX an intriguing option for the right user.
