A recent Kindle software update (version 5.18.3) introduces a new ad-filtering feature for ad-supported devices. This allows users to block potentially inappropriate advertisements from appearing on their Kindle's lockscreen and homescreen. The update, available for Kindle Scribes, Kindle Colorsoft, and 11th and 12th generation basic Kindle and Paperwhite models, also includes improved line and text spacing options. This feature offers a more family-friendly or professional reading experience by preventing the display of unwanted promotional content.
