Xiaomi mi 11 ultra has similar features with other devices of the same series. Its face can be easily confused. Not so with the rear panel. This is where the key design differences lie. We see a huge camera unit that takes up quite a bit of space and protrudes slightly above the rear panel. What's specific about the Xiaomi mi 11 ultra's block is that it has an additional display. We know it from the Mi Band 5. It comes into action when the smartphone is lying "on its face". On it, the user can read various information - time, messages and more. He can also use it as a mirror when taking a selfie with the rear cameras.

Another specific feature of all Ultra models is the back cover, which is made of ceramic. Meanwhile, the front of Xiaomi mi 11 ultra is protected by Gorilla Glass Victus and with a metal frame. The color of the body can be white or black.

Acting like a magnet in Xiaomi mi 11 ultra are its cameras. There are three of them on the back of the device and all are high resolution and have some features that are absent in quite a few competitors in the market.
