OK so far with my Samsung Galaxy S3. I initially received one that seemed to have an issue. It would intermittently save a photo here and there that would become corrupt a short time later. (The DropBox auto upload was fine so I know it was stored OK initially.)Amazon (excellent support) quickly shipped out a new one. The replacement has been working great so far! No sign of the issue I had with the first one.The only con is the time to display contents and read it in MTP mode if it has a lot of files.*** This is NOT the fault of the card. It's a known issue with phones in MTP mode.Note to Rooted GS3 users...I also tried putting the phone in the old unmounted USB mode. I was unable to read it but was able to read a 32GB version of the same card. It appears the GS3 does not support over 32GB in the old USB mode. Possibly part of the reason why they did not include a USB option via phone settings.
