Fire OS 3.0 brings with it «hundreds» of other enhancements, but the most noticeable ones include a new task switcher (which you drag in from the side of the screen), an app and content grid that you can choose to default to instead of the carousel, a redesigned Silk browser (
based on Google's Chromium) that features improved server - side caching and a new rendering engine, and a rewritten
email client that now includes
threaded conversations.
