I'd be careful about getting a Class 10 32GB, Samsung phone's seem to have a habit of killing 32GB Class 10 cards no matter the brand. Maybe a 64GB MicroSDXC will be better otherwise a 32GB Class 6 is what I'd get.
My GS4 just tore through my 2nd SanDisk Ultra U1 Class10 32GB, my GS3 ruined the 1st one, it's a huge issue.
