Interestingly, there is no fingerprint scanner and the phone relies on the front camera as a biometric tool to unlock the phone.
The front camera, along with a host of sensors such as a flood illuminator, an infrared camera, a ranging sensor and a dot projector, uses Oppo’s 3D structured light face recognition technology to unlock the phone. According to the company’s claim, the sensors used in the phone project over 15,000 recognition spots on a human face, thereby building a complete 3D facial model of the user to accurately recognise the face and unlock the device. This is a somewhat similar set-up first seen in the Apple iPhone X. However, Oppo managed to implement it without using a notch-based screen.
