I am getting a Samsung Galaxy S3 any day now. One reason is that it has a Micro SD card slot in the back (for music, files, photos etc.) . . . . . unlike an iPhone which requires more $$$$$. There are two SDXC cards that are compatible at 64GB (the maximum allowed in the GS3): The Ultra 64GB and The Extreme 64GB.
Please advise as to which one is most compatible with this phone. Thank you in advance.
