The Sandisk Ultra 64GB Micro Card is a great addition to maximize the Samsung Galaxy IIIS, whatever version you got 16GB or 32GB. Is a very fast memory at a great price. Plenty space for pictures, videos and Android Applications. Good for the 1080 videos that the Galaxy IIIS use. Super Fast. If you got the most advanced smartphone in the market as I do, this is the memory to get at the right price.
