This 64GB MicroSDXC card was bought for my Samsung Android S4 to give it more memory to be able to update current Apps on my phone and stopped it from telling me I was out of memory. This card solved my problems and it has also speed up my phone as well. I am very pleased so far with the performance and also they shipped my product really quickly as well. Very pleased with this purchase. The price cannot be beat for this size 64 GB card and performance and SanDisk put our reliable memory cards. There is a program that comes with this card that help you organize, keep your phone clean from too many Apps, keep the date from photos and videos becoming a memory hog. i did not use it, just put the card in and let my phone format it and it does just fine without the special Application with the card to keep your phone from becoming slow, sluggish and running out of memory space from photos, videos etc. I did not need that since I don't keep photos stored on my phone or keep videos. This card does have quite a bit of options for the price to give your older android Samsung phone the extra memory it needs since some of the Apps we like are memory hogs, one of them I can mention is Facebook which keeps updating all the time and taking more memory to run it on your phone and it works right for example for one memory hog application that everyone uses.
