为什么 phone 即使设置 none 重启后也需要密码？

Question

当我从安全 -> 屏幕锁定设置 PIN 并单击 "Require PIN to start device" 时，一切正常。这是用 "QSEECOMAPI"

过滤的日志

D QSEECOMAPI: QSEECom_get_handle sb_length = 0xa000
D QSEECOMAPI: App is already loaded QSEE and app id = 4
D QSEECOMAPI: QSEECom_dealloc_memory 
D QSEECOMAPI: QSEECom_shutdown_app, app_id = 4
D QSEECOMAPI: QSEECom_get_handle sb_length = 0xa000
D QSEECOMAPI: App is already loaded QSEE and app id = 4
D QSEECOMAPI: QSEECom_dealloc_memory 
D QSEECOMAPI: QSEECom_shutdown_app, app_id = 4
E QSEECOMAPI: SUCCESS::ioctl call to update the encryption key for usage 4 success with ret = 0

之后，当我再次 select 屏幕锁定 "None" 时，重启后它仍然询问 PIN，这是 selected "QSEECOMAPI" 过滤后的日志 "None"

D QSEECOMAPI: QSEECom_get_handle sb_length = 0xa000
D QSEECOMAPI: App is already loaded QSEE and app id = 4
D QSEECOMAPI: QSEECom_dealloc_memory 
D QSEECOMAPI: QSEECom_shutdown_app, app_id = 4
D QSEECOMAPI: QSEECom_get_handle sb_length = 0xa000
D QSEECOMAPI: App is already loaded QSEE and app id = 4
D QSEECOMAPI: QSEECom_dealloc_memory 
D QSEECOMAPI: QSEECom_shutdown_app, app_id = 4
E QSEECOMAPI: Error::ioctl call to update the encryption key for usage 4 failed with ret = -1, errno = 22

因此，日志中的最后语句显示它是关于 libQSEEComAPI.so 二进制文件的。我该如何解决这个错误？
