trying to print from an X-T2 to the Instax SP-2 did not work. The connection did always abort when printing. Tried android on an LG phone, did not work either. Was thinking about returning the unit but it finally did function from an iPad. The shipped firmware on the SP-2 is too old for direct in-camera printing. An upgrade solved that. A small note in the box would have been helpful. At least it's stated in the Fuji FAQ: http://instax.com/share/en/faq/
The Android phone did not find the printer as GPS was not turned on.
