I purchased the SanDisk Ultra 64GB MicoSDXC memory card to put in my Samsung S4. I tried to purchase this memory card locally (AT&T; and BestBuy) but no one had a 64 GB memory card. I am glad that I purchased the memory card as not I can put my backups, music, podcasts, etc... on added storage. I would recommend this memory card for anyone who has a Samsung S4.PCEddie[...]
