The Windows Device Portal lets you configure and manage your device remotely over a network or USB connection. It also provides advanced diagnostic tools to help you troubleshoot and view the real time performance of your Windows device.
The Device Portal is a web server on your device that you can connect to from a web browser on your PC. If your device has a web browser, you can also connect locally with the browser on your device.
Windows Device Portal is available on each device family, but features and setup vary based on the device’s requirements.
Starting in Windows 10 version 1511, additional developer features are available for the mobile device family. These features are available only when developer mode is turned on.
This tutorial will show you how to turn on or off Device Portal for mobile on your Windows 10 Mobile phone.
