In addition to more robust line and text spacing options, you now have the option to filter ads that “may not be appropriate for everyone” so they don’t show up on the Kindle’s lockscreen and homescreen, as spotted by The eBook Reader. It’s part of the 5.18.3 software update for the Kindle Scribes, Kindle Colorsoft, and 11th and 12th generation versions of the basic Kindle and Paperwhite, which adds two new lockscreen ad options accessible in the “Your Account” section of the Kindle’s settings. Although they can feature everything from cars to beauty products, the ads frequently feature books and are often based on your own personal browsing and reading habits. It will still be up to Amazon to decide what the company considers appropriate versus inappropriate ad content. If you’ve turned on ad filtering and are still seeing ads you’d rather not have showing up on your Kindle’s lockscreen, you’ll need to visit Amazon’s website and pay $20 to have the ads removed from your e-reader entirely.
