Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question. Please let me know what page, on what device, you are trying to advance, and I will advise you.
To move forward the page that you are reading, on to the next page in the e-book, in other words?
It depends upon your model of Kindle, perhaps, but try this:
Tap on the right side of the page.
(To go forward one page.)
Tap on the left side of the page (to go back one page.)
That works on the Kindle Fire - does it work on yours?
