Bought this 64gb micro SD for my galaxy S3 32gb smart phone.  Not only did it increase the size of my memory greatly,  the speed is noticeably better then the 16gb unit that came with my old DROID X smartphone.  I've put a thousand songs,  many pictures,  moved many apps to this storage unit and still have many gigs left both on my main phones memory and  memory card.  I will not purchase any smartphone that doesn't offer SD expansion,  and look forward to the next step to 128gb or higher.
