A side benefit of this is that the Mi 11 Ultra is stable when using it on its back on a flat surface. You can even use the bottom of the camera module as support for your finger when using this phone one-handed. Fingerprints are a big problem on the Ceramic Black variant, but you can also get the Mi 11 Ultra in white, which should hide them better. On the right side of the camera module is a 1.1-inch (126x294 pixel resolution) OLED display. This mini touchscreen automatically lights up when you place the Mi 11 Ultra face down on any surface. It can be customised to show the battery level, notifications, date and time, a custom message, or an image. You can also use it to answer or reject an incoming call. Most importantly, you can use it as a viewfinder for taking a selfie with either of the three rear cameras. It's largely a gimmicky addition, and looks like it was added mainly to fill the empty space at the back. I also didn't like the fact that the menu system for customising this display is buried in the Settings app and not easy to get to.
