Google has released a “preview” version of upcoming Android 5.0 KeyLimePie dubbed “Android L Preview”. This isn’t the final version nor is it recommended as daily driver but there’s some drastic UI changes.
My favorite feature on it is the new Lockscreen notifications. Although I have been enjoying this feature on most of my Android devices with use of custom ROMs, I am beginning to believe that Google is actually implementing a lot of features that are on custom ROMs into the official Android OS. It’s definitely headed in the right direction I think.
Overall, this is NOT a finished product but only a “preview” version for developers but you can install it if you have a Nexus 5. If you need to get really high on Android this weekend with your Nexus 5, check out How to Install Android 5.0 L Preview on Nexus 5!
