According to the patent, the primary display is like any other phone with ultra-slim bezels and earpiece up top.
Meanwhile, the secondary display on the new Xiaomi-patented phone is as small in size as the quad-camera housing on the back.
As per report, the secondary display will most likely show caller ID and notification alerts when the phone is placed face down. Xiaomi is expected to release the foldable phone by the end of 2019.
Additionally, there is no selfie camera on the front which suggests the secondary display might serve as a view-finder well to click selfies with the rear cameras.
Recently, the company patented a foldable smartphone with five pop-up camera setup.
According to the patent, this foldable phone has an outward-folding screen and depending on how a user holds it, the five cameras can either be rear cameras or front-facing cameras.
