if i enable the usb connection option “mount sd card”, everybody is allowed to mount the sd-card via usb, no password required. I am using the latetest version of fp open.
My (dumb?) question: Is there a way to change the usb/sd-card mounting options without having the ff2 connected via usb? I did not find them till now… :-/
You need to have the phone unlocked to mount the SD card; so if you feel it is unsafe this way, activate screen lock (e.g. with pin or password; you can find that in settings - security - screen lock).
On the other hand, as long as you haven’t encrypted your SD card, anyone can get data from your SD easily, by just taking it out of the device and plug it to a computer.
