The Oppo Find X may include a telephoto lens with 5x lossless zoom support2
See, aside from the image, the poster is also accompanied by the phrase “Focus on the sky and the universe to unlock it.” It’s presently unclear why Oppo would have included that message on the poster, but it could be a reference to a potential face scanning feature. In recent times face unlock has become extremely popular among Android devices due to Face ID on the iPhone X. However, unlock Apple’s variant which uses 3D facial scanning technology to ensure a high level of security, Android devices simply rely on the selfie camera, the only exception being Xiaomi’s Mi 8.
It’s certainly possible that Oppo may have developed a Face ID-rivalling technology by now, but taking into considering the relatively small notch that has been seen in recent Find X renders, it would likely be impossible to fit the technology on the device, therefore suggesting that the Find X may simply offer a Face unlock feature akin to the OnePlus 6.
