How to disable page flip feature for MOBI file
It appears Amazon has found a way around this hack 🙁
There is a claim among many indie authors who have performed tests with their own books, that the Kindle “Page Flip” feature can cause erroneous “pages read” to be reported back to Kindle Unlimited (KU) for books enrolled in the program.
The issue seems to occur when KU customers read any of the participating books while “Page Flip” mode is activated in their devices. In the worst case scenario, a KU customer might read the entire book in this mode, resulting in a complete monetary loss for the book’s author. Amazon’s position states that this is not happening and that their page-counting algorithms contain no errors.
For my part, I wanted to be on the safe side and figured out a way to disable the feature. Below I describe the method step by step. For my ebook-generating process, I create my .epub files in Scrivener, then use Kindle Previewer to create the final .MOBI file that is required for Kindle. Try this at your own risk weighing in the decision of turning off a Kindle feature that readers might enjoy.
- (1) Select and copy ALL the code found in the box below. The code represents a scalable vector graphic or SVG. This particular SVG is a scene separator that looks like the image under the code box. If you would like to use another image, it is possible to convert any .png or .jpg file into an SVG. The code looks like gibberish and that’s okay 😉

[/php] - (2) Open your .epub file in SIGIL. Sigil is an .epub file editor which is what I use to modify the files that I generate in Scrivener
- (3) Content in Sigil is displayed within .xhtml files, so you have to find the right file where to add the SVG. You might have to double click and search within a few of these .xhtml files before you find the right place. I added my SVG only once, right under my dedication text. Easy!
- (4) With your .xhtml file open, click the “Code View” button in the toolbar. This will allow you to see the mark-up language ONLY. You could also use the “Split View” button, if you prefer to see the mark-up language and preview at the same time
- (5) Paste the SVG code you copied in step (1) in the exact position where you would like it to appear. Be careful to preserve the integrity of the mark-up code, ensuring all tags are closed correctly
- (6) Click the “Book View” button in the toolbar. You should now be able to see the SVG image of the separator in the preview
- (7) Save your changes
- (8) Open Kindle Previewer
- (9) In the file menu, click “Open Book” and select the .epub file you saved in step (7). Opening the .epub file initiates the process of converting it to MOBI. Once the process is complete, Kindle previewer will inform you in what drive location the file was saved. I found that the previewer does not actually show the separator, so don’t be alarmed about that
- (10) The .MOBI file generated will disable the PAGE FLIP feature once uploaded to KDP
I hope these instructions are clear. If you have any questions, write them in the comments section.
I followed your directions and ended up with the page break design showing, but page flip still enabled once it got to Kindle.
Are you still using this method? Is it still working?
Is there a way to figure out where to put the code so it will work?
It seems that Amazon has found a way around this, as my books no longer have the flip feature turned off 🙁
Hmm. I think Amazon has found a way around this because it didn’t work for me. The image appeared in Sigil and all seemed well in Kindle Previewer. But after the book went live, I waited two days, but page flip continued to be enabled.
Hey, I just wanted to thank you for sharing this code. It’s made a huge difference the first day once the new versions of the books went live (300% increase in my page reads.) I never would have known the actual numbers if not for the ability to remove the page flip feature. I suspected every time I re uploaded my books back matter, but the feature would turn back on too quickly to get an accurate number.
