The first manufacturer to introduce a foldable smartphone was Royole, with its model FlexPai. However, he was clumsy and we certainly did not imagine the solution of a folding smartphone. Then came big players, Huawei and Samsung. They introduced much more interesting devices. Huawei X Companion it is not sold yet Galaxy Fold It faces display issues so we still do not know how to start selling it.
We have not had this combination yet
Neither of these devices offers an ever-popular sliding camera. The first manufacturer to offer a folding screen combined with a selfie sliding camera can be the Chinese Oppo. The device appeared on the first render and does not look anything bad. The folding principle is the same as the Huawei Mate X.
The eject camera ensures that the device does not have a clipping on the display. However, the main camera, which should be in the back, is not visible in the photos. In any case, this company solution Oppo it is still only a patent and shows how the device might look like. It is not your final form. That may change. The selfie sliding camera will surely be the biggest draw along with the folding mechanism.
The company is still silent about the smartphone. Of course he's working on it, but there's no information on the approximate date of the show. This is unlikely to happen by the end of this year.
