My son has a Galaxy tab E, and I want to give him some of the books on my tablet. Smart switch doesn't even show them so I can't use that. I sent him one book by email, but how then does he get it onto his tablet, and where does he put it? The Books folder only shows up when connected by USB to a PC.
So what do we do to get books from one tablet to another?
Welcome to the forum Aravis! If it's a Kindle book, you could use their Family Library feature. Unless there are restrictions on the file, you couild use a file sharing app, like dropbox, or sign into your account using his tablet.
