TL;DR Samsung killed its “classic” DeX in One UI 8, replacing it with a new version built on top of Google’s native Desktop Mode in Android.
This move aligns DeX with Google’s broader effort to improve Android’s desktop capabilities, which should benefit DeX in the long run.
However, the new DeX is currently a downgrade for users, as it lacks many quality-of-life features that were present in the classic version.
Samsung DeX is one of the best features of One UI, letting you transform your powerful Galaxy phone or tablet into a portable PC. You simply hook up your Galaxy device to an external display, fire up DeX mode, and connect some accessories, and you have a full desktop experience. DeX has evolved over the years, but the latest One UI 8 release brings its most significant changes yet. Samsung has killed off the “classic” DeX experience, replacing it with a new version that’s arguably a downgrade for now. However, this change is poised to pay off handsomely in the future. Here’s why.
Samsung introduced DeX with the Galaxy S8 series in 2017, over two years before Google added even a rudimentary desktop mode to Android. Because Android natively lacked much of the functionality DeX required, Samsung had to make significant under-the-hood changes to the operating system. For example, Samsung modified core Android components to add its own desktop windowing system, a dedicated desktop launcher, and an improved connected display experience. This required a massive effort that didn’t stop at the initial launch, as Samsung had to carry these custom changes forward through multiple Android releases.
Samsung is in the business of selling Android phones and Windows PCs (…and a ton of other things), though, so they have little incentive to invest heavily into transforming Android into a full-fledged desktop OS. As a result, DeX has long been just “good enough” for casual users wanting to watch media or do light work on the go, but it has never been robust enough to fully replace a traditional PC for professionals.
Google, however, is a different story. The company has spent years trying to break into the PC market with ChromeOS, which has seen major success in the education sector. But developing two operating systems simultaneously is inefficient, so Google is pooling its resources to merge the two platforms. This effort involves bringing many Chrome OS features to Android, such as a desktop version of Chrome with extension support, a Linux environment, and more.
As part of these efforts, Google is finally adding proper desktop windowing and a new connected display experience to Android. The Android 16 release introduces a Desktop Mode with many DeX-like features, such as a taskbar at the bottom and support for freeform app windows. This new mode is, in fact, built on the very foundation of Samsung DeX. Google and Samsung collaborated to improve desktop windowing on Android, culminating in the new experience we see today.
With Google now developing a native desktop mode for Android, there’s no longer a need for Samsung to maintain its own heavily modified version of DeX. Doing so would be counterproductive, requiring Samsung to constantly adapt its code to Google’s changes and risk breaking compatibility with apps built for large screens. While phone makers often stick with their own software features even after Google introduces a stock equivalent, this situation is different. Desktop Mode is poised to become a core part of Google’s future Android strategy, making its adoption essential.
