So I ordered a Micro USB SD card reader for my Edge+. It works great! It is from Meenova. I also bought a 64GB SD card. While I can't figure out how to change storage locations for the default camera app, I was able to set it up properly with Camera Zoom FX so pictures taken will save to the SD card if it is present. If not it saves to the phone.
