Why build a Samsung DeX compatible app?

Reports show that 74% of IT workers use two or more devices for work, 52% used three or more. This increasing fragmentation causes lost productivity. Samsung solves this problem with Samsung DeX and brings the PC-like experience to Android.

Samsung DeX compatible apps utilize the powerful features offered in Samsung DeX Mode. This robust, multi-tasking environment encourages users – and provides them with the technical capacity – to adopt Android as a primary ecosystem for any task: word-processing, photo-editing, games and more. Apps that are not modified to be compatible with Samsung DeX can still be launched, but operate in a fixed-size window with limited functionality.


Apps in Samsung DeX take advantage of Android N's new Multi-Window features. Users can open multiple apps in the same session to work, connect and interact seamlessly together.


Apps launched in DeX mode can be expanded into a full screen, immersive window. Showcase the full features of an app without the expense of screen real-estate.


Samsung DeX compatible apps add powerful features to the mobile experience. Drag and drop files between windows, copy and paste between multiple apps, ALT+ TAB, and more.

How Samsung DeX works

Samsung DeX is an extension of Android N's Multi-Window mode. Additional code development has also been included by Samsung that adds extras features and integrates it with Samsung hardware, such as the Iris scanner. There are no proprietary Samsung APIs needed to launch apps in Samsung DeX, as it is enabled by default. Apps typically run as long as they adhere to Androids best coding practices.

Samsung DeX offers many different features to best suit your needs. Samsung DeX Mode allows your device to cast a PC-like experience to the big screen with the same apps you use on your phone every day. Finally, You can use DeX mode on your monitor or TV or PC(windows and mac OS) while simultaneously using different apps on your device, or turn your device as an input device to control the DeX environment. Additionally, work and play where you like with Samsung DeX and your tablet. A tap of the Quick panel switches to DeX mode, allowing you to use your tablet just like a PC.
