它是如何觸發的？
這個值的狀態是燒錄在主板上，無法刷寫修改， 從0到1 不可逆，除非替換硬件
If a non-Knox boot loader or kernel has been installed on the device, Knox can no longer guarantee the security of the Knox container. As a result, the Warranty Bit will be burned to 0X1, indicating that this device can no longer use the Knox container service.
If the Knox bit has been burned:
A new Knox container can no longer be created on such a device
The data encrypted and stored in an existing Knox container can no longer be retrieved
進入刷機模式以后， Knox WARRANTY VOID: 0x01.表時Knox安全套件已經失效，那么ro.boot.warranty_bit＝1，三星大多數app會根據這個值來決定，你有沒有權限繼續使用三星官方應用。
為了安全考慮，三星將不會讓你使用如三星支付、三星健康等app
