I use Kindles and occasionally will open the book to find it back one page or forward one page, which is not a big deal.
On a previous Kindle I remember where an up or down swipe, as opposed to a crossways swipe, would take you back to the beginning of the chapter or to the next chapter. I thought the Kindle was faulty until I read about the cause here in the forums. It was very annoying until I twigged to using "back" to get to the right spot
