Bought 1 to expand capacity on a Galaxy S3, and another to expand capacity on a Galaxy S4. Have used the one for the GS3 for about a year, and the one for the GS4 about a month. Both have worked without any problems, and are fully recognized by the devices. The GS3 was rooted a couple of months ago and is running LiquidSmooth. Still no issues. Very good card. I highly recommend SanDisk.
