I just got a Moto G4, my 1st smartphone, and since I like to read ebooks I installed Bluefire on it so that I could read them like I do on my IPod Touch and Samsung Galaxy Tab E. I noticed that when I downloaded the .pdf file to my computer and attached all my devices that the phone did show up as a device but there didn't appear to be a way to copy the file to it, as there is on my Galaxy tablet. I haven't been able to figure out how to do it. The phone does have an 8 gb SD card but no matter what I've done, I can't seem to get it to work. Help? Anybody?
