How to get the "Encrypt external SD card" option to show (on a LG Optimus F6)? The &quot;Encrypt external SD card&quot; option doesn't show up under Settings -&gt; Security on my LG Optimus F6, or my Huawei Y301-A2.
A microSD card, FAT32 formatted and empty, is inserted and recognized correctly. The &quot;encrypt device&quot; option shows up, but the &quot;Encrypt external SD card&quot; does not.
How do I get this option to show up? This is using Android 4.1.2
I don't know about those exact models, but on Jelly Bean in general, you must enable a password on your phone to encrypt external SD.

Security  -> Set up screen lock -> Password.

Then you'll need to set a password for the SD.
