Insufficient Storage with new sd card I have a ZTE N817 and I bought a 16GB sd card for it and when I try to download something, all it says is that there is "insufficient storage on device". What should I do to get my phone to register that I have am sd card full of untouched storage?
That is because your device downloads data in your device internal memory by default and you don't have sufficient space on your device internal memory  .
In this case you can transfer some data  to your sd card such as media files or change download location to sd card.
