I have tested this card in both a Samsung Galaxy Note 3 phone and aSamsung Galaxy Tab 3 (10.1-Inchand it was immediately recognized by both devices. As I write this review the card has been running in my Tab 3 and constantly used for over a week.Other reviews have dissected the specs of this card, so I'll share how I use it and why I prefer these over the 64GB cards (which I also own and use). The price point on these 32GB cards have dramatically fallen and as of the date of this review they are priced as commodities. I use a few pairs of these to rotate backups on my laptop, so I always have a daily snapshot of my documents. For that purpose alone these cards are well worth it.For my tablet I have divided my extensive music library into genres and have them backed up to these cards. A 32GB card will hold about 150 CDs, so the space savings along over the physical media is significant. In fact one of these cards cost about the same as a rack for 150 CDs.These are also excellent for saving practice sessions that I sometimes record using my phone or tablet. I pop my primary SD card out of the device and swap one of these in to video record. Since this card will hold about six hours of video it's perfect for that use.Overall, these are reliable cards that have worked in a number of devices I own. I can assure anyone wanting to use them in a newer Samsung Note 2 or 3 phone or Tab 3 tablet that this card will work, and it is also excellent for HD video recording. At the price point it's an absolute bargain.
