Why can't I use the SD Card as Internal Storage?
Question kinda says it all, but here goes; just recently got a 64-gig SD card to keep my apps on in my phone , which is a Z837VL, and am unable to see the instructions that would let me set it as internal storage. Google results just keep telling me to pick the option that isn't there in the first place. Phone is up-to-date, otherwise.
Any thoughts? Is this just really, really obvious, and I'm being an idiot?
