Understanding Samsung DeX
Samsung DeX transforms compatible Galaxy devices into desktop-like experiences. It expands functionality and productivity options for users.
What Is DeX Mode?
DeX mode turns your Galaxy phone or tablet into a PC-like interface. It displays apps on a larger screen and supports mouse and keyboard input. This setup allows for easier multitasking and improved productivity.
When activated, DeX presents a familiar desktop environment. You’ll see a taskbar, resizable windows, and desktop icons. It’s ideal for tasks like document editing, web browsing, and running multiple apps simultaneously.
DeX works by connecting your device to an external display. You can use a cable or connect wirelessly on supported models. The phone or tablet then acts as a touchpad and virtual keyboard.
