I've read of problems with Class 10 ratings & that Samsung S4 not being compatible with UHS-I. I need to expand my memory asap & purchased a SanDisk Ultra micro SDHC UHS-I 16gb Class 10 card. I haven't opened/installed on my S4-dont want to until I'm certain of compatibility. Has anyone been successful using this sd card? If not, what seems to be the next best alternative out there?
