It has been revealed that this series of mobile phones has two unlocking schemes in the engineering commissioning stage, but it has not yet determined which scheme is used for mass production machines.

The first scheme is to use a new 3D structured light+post TOF, while the second scheme will use 3D structured light+screen fingerprint. It is reported that the screen fingerprint sensor of Mate 20 is a mixture of Synopsis and Huiding Technology, while the algorithm of 3D structured light is developed by Huawei, and the module supplier has not been determined yet.

According to the revelations from the industry chain, Huawei is negotiating with four 3D structured light suppliers, namely, OPI Technology, Guangbao, Sunny and Qiuti Technology. It should be noted that the new Xiaomi and OPPO machines also use 3D structured light, but the algorithms and modules are from suppliers.
