Bought this for my HTC Evo 4G LTE, it works great, I knew in order to use such a big card it had to be a Class 10, and I only trust SanDisk, Samsung, or Kingston with my memory cards. This one works well, it did take about a day for the &#34;bugs&#34; to be ironed out and let the Evo find its paths back to its files. This is a very good stick at a very good price. The first one I got from Amazon was damaged, they quickly replaced it..... with one that was lost by FedEx!!!! I called up about a week later and they overnighted a new one, and paid for weekend UPS delivery! I was amazed at the service from Amazon on this.All-in-all, it doesn't get much better than SanDisk for memory, and Amazon for the place of purchase. Don't hesitate to buy this card for your HIGH END phone. I know for a fact that the HTC Evo LTE & Galaxy S3 can run this card.
