My Galaxy Tablet 7.0 works fine with 16gb microsd cards, but when I insert a 32gb card, it becomes unstable, then freezes and/or crashes. These cards are made by Transcend and bought new from Amazon so I don't believe they are fake. The product description is Transcend 32 GB microSDHC Flash Memory Card TS32GUSDHC4E. My PC verifies that there is more than 27gb of free space on the card. I believe that my Galaxy tablet is designed to handle the 32gb cards. I would appreciate any advice the Forum can offer so that I can utilize the larger-capacity cards.
