I seriously doubt this is the case. Amazon's business selling ebooks is much more significant than their business selling proprietary Android devices.

And the page turning problem also occurs on my Kindle Oasis.

Huh. I had no idea the problem was this widespread. For the record, I've never had a problem on any iOS device or Kindle e-reader (iPhone 5s, iPhone 6, iPhone X, iPad, iPad 2, iPad mini, iPad Air, iPad Pro, Kindle Paperwhite, Kindle Voyage). I am stunned that it happens on the Oasis.

If I were guessing, I'd guess that the problem is related to Amazon's new-ish feature of supporting page numbers as well as locations. My workaround for the page-turn text skipping issue is to jump to a nearby location (e.g. if my location before turning the page is 4384, try to jump to 4387). On some books, this isn't possible; there is some defined magic page-starting point and jumping to any nearby location means you jump to that point instead. This aggravates the problem.
