Surface Duo is almost here, and initial impressions from the press have been extremely positive, particularly when it comes to the build quality, industrial design, and just how thin Microsoft has managed to make it.
With that thinness, and the fact that the Surface Duo is covered in glass on the back and the front, it isn’t too surprising that Microsoft decided to include a bumper case in the box with every device.
Watch the video below to learn how to properly connect the bumper to your Surface Duo.
Microsoft confirmed that the bumper is designed to only attach once, as the adhesive will wear off once the case is removed. So if you’re the type of person who likes to switch cases often, you might want to wait for third-party cases instead of using the bumper provided by Microsoft.
