Hello,
if you use Android 11 or higher, there are restrictions from Google get this permission. You can find information on "developer.android.com".

If you need read or write access, then you can put this lines to the post-install script:
afw_set_permission_grant_state com.xxx.yyy.app android.permission.READ_EXTERNAL_STORAGE allow
afw_set_permission_grant_state com.xxx.yyy.app android.permission.WRITE_EXTERNAL_STORAGE allow

Sincerely

OEMs like Zebra and Honeywell provide OEM specific methods for silently granting these sort of permissions. I am not sure about Samsung but you may need to check within the Knox specific documentation to see if anything similar is available.
