I got the micro sdcard 64gig, I reformated to fat32 and works very well on my galaxy s2 i9100 with no problems at all, thanks:DEDIT: After 7 months of using this memory card, now i tried to format it but it wouldn't, i tried about 5 different methods and none of them worked, i wouldn't recommend buying this one: SanDisk Ultra 64GB MicroSDXC Class 10 UHS Memory Card Speed Up To 30MB/s With Adapter, Frustration-Free Packaging - SDSDQU-064G-AFFP-A. Avoid buying it or you will experience problems in half a year.
