The "Encrypt external SD card" option doesn't show up under Settings -> Security on my LG Optimus F6, or my Huawei Y301-A2.
A microSD card, FAT32 formatted and empty, is inserted and recognized correctly. The "encrypt device" option shows up, but the "Encrypt external SD card" does not.
How do I get this option to show up? This is using Android 4.1.2
