Amazon is still trucking along with its customized version of Android -- though we'd imagine updates are more focused on the company's Kindle Fire tablets and TV hardware, rather than the disastrous Fire Phone. Developers can get their hands on a preview version of Fire OS 5 today, while the final version is coming later this fall. The new OS finally brings Android Lollipop to the company's devices, though you likely won't see many of Google's interface improvements under Amazon's skin. The addition of Lollipop should also make Fire OS 5 compatible with more Android apps than before. Amazon's also updated its online testing service to tell developers if their apps are compatible with the new OS in 90 seconds.
