The OS isn't exactly from Google. What really happens is the tablet maker ports the OS to the tablet and you may or may not have the features you are after.
Since it has a slot for the SD card, why not put files on that?
recently bought a (no name) tablet with android 5.1.1 lollipop for my grand-daughter...
i want to put her music and videos on the machine before i give it to her, but OTG/mass storage/USB connection is not available... a quick Google shows a lot of 'experts' with differing opinions...
2 questions, does 5.1.1 allow any of the above?
if not, how do i transfer files to the tablet?
many thanks for any and all help
the tablet has:
1 hdmi port
1 mini usb
1 slot for SD card
