i have this problem everytime i switch to windows 10 even though i have all the drivers it never recognize any sd card. what i did is go to settings, update, recovery and click restart in uefi mode then when restarted choose advanced option choose reboot with boot menu when it reboot you will six case boot menu. without doing nothing further restart manually and miraculously my 64g sd card is there. but if your sd card is not recognized in android too then maybe its the tablet.
