The card needs to be formatted in FAT32. and Jelly bean(android 4.1) did not reliably move apps to the card. Also the programmer may have not thought of it as well.
Not sure about formatting. I bought a microSD card, inserted it and have had no problems sending apps to my card. Maybe your card is defective.
Go onto settings/storage make sure to unmount, and mount storage, also, you can erase the storage there as well. Really not sure why you are having these problems, I have great results with my polaroid sd card, but it is 16GB. It is probably just a setting, It took me about a week to figure that out. ALSO, IF YOU HAVE ANYTHING CHECKED UNDER DEVICE ADMINISTRATORS, IT WILL PREVENT SOME WRITING AND INSTALLATION TO YOUR SD STORAGE, UNCHECK THESE, DO WHAT YOU NEED THEN RE CHECK THEM. DEVICE ADMINISTRATORS LIKE ANDROID AND LOOKOUT OR EVEN AVG.
you have to choose the ext. sd card and not just sd card
You need the mini sd card not the reg size sd card.
