Carla is looking for a good microSD for her Samsung Galaxy S3, but she keeps hearing about them crashing. Leo says that microSD cards can crash like anything else. Sandisk is his brand of choice. What class should she get? Leo says class 4 or better is fine, but she shouldn't spend a lot of money on class 10 cards because a cellphone can't really use that speed. Since they can crash, it's vital for her to back up her images and videos as often as she can.
Leo says it isn't a problem with the cards, it's an autorun program on the SD card that is running that prevents it. He can remove the programs by formatting them (using a camera is great for that). Leo says to buy cards that are made for photography. They come with no additional autorun software.
