Xiaomi's SU7 car has undergone a system upgrade to HyperOS 1.2.7, introducing key features like external wake-up defense and front vehicle recognition. This system update brings the highly anticipated 'external wake-up defense' functionality. When the vehicle is in P gear, the central control is locked, and all doors and windows are closed, this feature will automatically activate, effectively blocking voice wake-up attempts from outside, significantly enhancing the vehicle's security. This improvement directly addresses user feedback regarding the safety risks associated with external voice wake-ups.
