When an app is installed and has access to your SD card, can that app access anything on the SD card? Photos, etc.
I am not a developer, but as I understand it the SD cards are a FAT file system which does not allow for file system permissions. This is needed because they are removable and the data needs to be accessible by other apps once inserted into another device. Does this make any data stored on the SD card readable by potentially malicious apps that have access to or are installed on the SD card?
