Some devices yes can use the 32 gig sdcards. Best thing to do is Google the device your checking and see if you can get a techical specs breakdown on it and that should say if it excepts it or not. I would say most phones in the last 6 months to a 1 yr are now capable of 32 gig cards. I will note, even those that do "run" the 32 gig cards aren't always capable of formatting them in the device. There is a 16 gig limit for formatting on some devices, in that situation you would turn to your computer and a card reader/adapter to format the card if need be.
