I've had this memory card in my S3 for the past few months without any issues. The only problem I've had with this was when I initially copied the 30GB of data from my old card to this card. I had this connected to my laptop using a MicroSD USB adapter and the copies kept failing. I figured out that the card was overheating when writing a lot of data. I was able to copy the data by pointing a small desk fan towards the card adapter during the file copy process. That being said, I don't have any read/write problems due to overheating with the card installed in my phone. I've copied over a couple of gigs of movies to watch on some trips with the card installed in the phone without any failures. It may be that heat issue only occurs after pushing &#62;3GB of data at a time. The largest movie I copied to the phone was 2GB. Most of the other movies are just over a gig.The only prep work for use in my phone was the initial format when it was first installed. The card was recognized prior to the formatting but I had seen where others had read/write issues so the format was a preemptive move.
