There is Factory Reset Protection (FRP) bypass security vulnerability in P20 Huawei smart phones versions earlier than Emily-AL00A 9.0.0.167 (C00E81R1P21T8). When re-configuring the mobile phone using the factory reset protection (FRP) function, an attacker can login the Talkback mode and can perform some operations to access the setting page. As a result, the FRP function is bypassed.
