Why did you try to format in windows to fat32 you know sdcards are already set to fat32 so you can automatically put it in your phone ready to use and even if it wasn't formatted to fat32 you still put it in your phone and your phone gives option to format no windows requiredOld thread I know, but I just put a 64GB Sandisk Ultra (80mb/s) card in mine yesterday. No issues so far, but it was tricky to find a way to format in FAT32 as Windows Explorer in Windows 7 wouldn't permit it. I eventualy used fat32format, which worked perfectly.
