Galaxy Tab S2 doesn't recognize MicroSD card

[AC Question]

My new (two weeks) S2 will not recognize the 128Gb MicroSD card I bought for it. It doesn't recognize the 32Gb MicroSD card I took out of my S5 to check either. Using a card reader my W10 PC does recognize the card and I was able to copy a file to it. The S2 does not recognize the card and I have tried several re-starts.
Any suggestions? Is there an install routine? I don't think so.
BTW, I really don't like the silly tool you have to use to get the slot open.

Hi and welcome to Android Central.

Just to cover the basics. Galaxy Tab S2 - How do I insert or remove a microSD ™ card from my Samsung Galaxy Tab S2? Installed correctly?


Correct format? Galaxy Tab S - How do I format the microSD card on my Samsung Galaxy Tab S?

Yes, the card is installed correctly.
I cannot reformat the card in the S2 as it does not recognize it all. The S2 did not recognize the MicroSD card I took out of my S5 phone for a test either.
When I loaded it into my PC using a USB card reader I believe the format was exFAT. I was able to add a file (photo) to the card OK, so the card itself seems OK, it is the S2 that seems to have a problem reading or even detecting the card(s).

SOLUTION
Problem fixed by formatting card using the SD Association formatting tool.
Why this worked is beyond me. The card (PNY) was brand new, already formatted exFAT and was visible to my W10 PC. There must be some subtle difference between the O/S formats.
Long story short, now all is good.
