Just Google "sd to microsd converter : dx.com"
6 bucks. I've found back covers and protective cases that will house this easy. And possibly a bigger battery as well, since that's what those covers are for....IF there's room above the battery and below the camera, for the converter. Idk though. I'll have to get my hands on the converter, then go to world of wireless to check out battery's and back covers. I don't think I'd mind my s4 feeling a bit more thick/heavy.
Def doable. And for a lot less then even a 64gb micro.
It's odd this product isn't more well known. That must be the retailers trying to hide it from the public by not producing it or selling it in their stores. For about 26 bucks, plus the cost of a reg sd card, you can have 4 times the space widely thought as currently available.
