Thank you for the link. Can't my questions be answered at this site instead of the site that you linked?
I'm sure many users here are experienced with Android as users, but the number of us that are experienced at providing
support for Android devices is probably far less.
For example I did write a post previously where I basically took my Nexus 6 and laid out the steps of how I got to what I think is the emulated SD Card.
I didn't post it, however, because I realized
I had no idea what I was talking about! A Nexus 6 is NOT a Polaroid Tablet, after all, as the Android versions will be significantly different, and steps where I explain how I bumble through changing a download folder will likely just confuse further as I'll likely be referencing elements that don't even exist on yours. Mine doesn't even have an SD Card slot so I would only be presenting it hoping it actually helps.
The main problem is that it sounds like you need specific instructions, which because of the nature of the Android ecosystem, is rather difficult to do unless somebody has the exact same device.
