I can not access or retrieve from any external storage. I have external HD connected with USB and a SD card inserted but neither one shows up in file manager. In settings I have mounted the external HD but still not showing up in file manager. Slate has been pretty useless because of this.
In settings under Model number it says Slate 21 Theres a build number as well I am using the same cable that I use to connect my external HD to pc Slate does have a SD card slot as well Running android 4.4.2
