Xiaomi has implemented four different designs on how to put the dual selfie camera cluster on the front. The difference in these 4 types of design is how the border around the camera sensor. One of them has a fingerprint sensor on the back.
The cameras are located in a strange position but still reasonable, quite optimal in terms of space. The rear camera cluster of these 4 designs has a few small changes but nothing new.
It is known that these are photos of Xiaomi's design patent file that were granted by the Hague international design system. And since this is just a patent, it is not known if Xiaomi will make it in the future. Only time will tell us the exact answer, so let's wait and see.
