Hey lc97400, could you add more details? What is the security policy in question? What exactly happens? Your phone should be compatible as per this link:

hi it was working until one day i can't remember, probably after an update last year. I tried many tricks but impossible to recover this function. Below screenshots when i plug a usb memory that was working before. It's detected by fx explorer or any else file browser but unreadable because forbidden by the phone
