Hesh!
this is my 3rd sandisk micro sd card for my 3rd android device, and just like its predecessors, the Ultra 64gb micro SDXC class 10 worked flawlessly in my SCH-I605 Samsung Galaxy Note 2.i simply inserted the card, power-cycled the device, and once rebooted, the Note 2 recognized an unformatted sd card and asked if i would like for it to be formatted in order to be read. once i chose YES, i now had an additional, fully usable micro sd card that i use for media and ebook reading storage.the response time is excellent, so i have no complaints on performance.i also love the fact that i ordered this at 3pm on Thanksgiving day when i was alerted of the $39.99 price tag.
