I am having a bit of trouble with my S7 Tablet. I can't get it to Recognize, and open my 64G SD Memory Card. Where do I go, and what do I do? The 64G, is no way near full, It's basically telling me, my SD Card is not Installed.
Stick it back into the device you took it out of if used. Mount and unmount it. You may have to drag and drop the contents on the original device or in a laptop. Reformat the card in the S7 and then copy, usb to usb, dongle, external hard drive, phone, etc onto the tablet as work around so you don't lose your data. The card is likely still useable after formatting it on your tab s7.
