A:Answer Generally speaking (and I don't own Apple products), most if not all micro SD cards no matter the capacity should work if they fit in the phone itself. As far as I know micro-SD card slots haven't changed for a while. Your phone software may limit what it reads uo to 32GB (which is the capacity of your Samsung phone you mentioned I looked up for you [hint-hint). Newer cards typically retro-work with older phones. They have higher write speeds but your older software may only write at its pace NOT the pace of the card itself. So, if the card is 64GB and 100MB/sec and the phone is 32GB software written at max 50MB/sec, you can only expect the latter capacity/speed. You might be spending more for less so check if a 32GB at your phone's speed will cost you less. But you might also consider if you'll be upgrading to a Samsung Newer model later, you can take advantage of this card's superior specs and not have to buy another later.
Just some thoughts . . .
