I feel like when I change pages back and forth in a book, the position of the text changes if I go forward a few pages and then back again. Has anyone else noticed this? For instance if the current page ends at say verse 8, then I move forward a few pages, then go back to my initial page, it may now end at verse 3. Not sure if that makes sense. It happens when I move forward or backward. I'm using an Android 4.4.2 tablet.
