Got it to use with my HTC Evo (Android) phone. It works great! To ensure formatting worked I simply put the card into the phone, and then connected the phone via USB to my computer and transferred the files via USB connection. The files and phone worked fine. A little storage space was lost due to the Android formatting or something or other, but with that much space I didn't notice. I have had 10 movies and tv shows on my phone and still not run out of space.
