I just got a QLink Specter 8 tablet. I’m trying to insert a SIM card and an SD card into the tablet. I’ve found the TF slot, and I’ve put the SIM card there, but I can’t find a place for the SD card. I can’t find a manual for the tablet, so I can’t figure out where to put the SD card. I can’t even figure out how to open the tablet to get to an internal slot for one of these two cards. Can anyone help me out?
