What is Samsung DeX?

Samsung DeX is a service that provides a desktop environment by connecting a smartphone to an external display (television or display). This service allows you to use your smartphone like a computer, and you can easily use your smartphone features on a large screen.

There are two main ways to operate Samsung DeX:

(1) keyboard + mouse operation

Of course, because the third-generation DeX accessory cable has no additional interface, the keyboard + mouse here is preferably the most convenient for Bluetooth. If there is a USB Type-C interface USB extender, I don’t know if the wired mouse and keyboard can be connected. Row. I haven't all of the things mentioned above, so let's talk about others here. Using the keyboard and mouse operation mode, it is closer to the traditional PC desktop operation, double-click to open, right-click the menu bar, use Ctrl + pulley to achieve page zoom, people who will use Windows will definitely use Samsung DeX, people who will not use Windows (I believe it is also a minority), and I will adapt quickly.

(2) Operating the mobile phone as a touchpad

The phone screen can be operated as a touchpad without a keyboard and mouse to connect. After entering Samsung DeX, select the use of your mobile phone as the touchpad in the drop-down notification bar, you can click and other operations, the operation is similar to the touchpad on the laptop. This kind of operation is actually experienced, and some simple operations can be performed. Of course, long-term heavy use is not recommended.

Sum up

Samsung DeX gives me the feeling that freshness is not enough. Samsung DeX's clean and refreshing interface and the perfect app on the big screen are better than the mobile phone screen. Lightweight office or presentation is also very suitable, the real office is still on the PC. With screen sharing, it is a good experience to screen a large movie, but nowadays wireless projection technology is popular, and the demand like me is only a small crowd.l crowd.
