The photo shows a folding smartphone, going to the screen out. Reminds Huawei Mate X. At the same time it is visible that the left half will be thicker than the right. But this is not the point!
What did you decide to surprise at Xiaomi?
To abandon any framework had to use a retractable camera. Moreover, this is the first time that it has 5 modules at once. For obvious reasons, the front camera is missing.
At present, it is not possible to discuss the possible price and date of presentation of the novelty. This is just a patent. Do not forget that the Chinese manufacturer has a large number of registered patents for folding phones. But the novelty looks quite attractive.
