Android 5.0 Rolling Out to Older Nexus Devices Right Now

Android 5.0 Lollipop has started rolling out to previously launched Nexus devices and that happened over the past hours. The release’s delay was caused by some software bugs having to do with battery life. Right now, if you own a Nexus 4, Nexus 5 or Nexus 7 you should be getting Lollipop soon.
The thing is that the rollout takes place in waves and Google didn’t exactly specify how long it will take. In the past it spread to as much as 3 weeks in order to cover the whole user base. Android 5.0 Lollipop brings design changes within the Material Design standard, more complex animations, a better looking multitasking area with vivid thumbnails and battery improvements. It also expands microSD card functionality and increases security.
There’s also a card-based notification system and enhanced and improved versions of all stock apps. If you haven’t got the patience to wait for the update, you should know that Google has released the factory images for the Nexus 5, 7, 9 and 10. So, people which programming and hacking skills, who know how to work an Android SDK may flash Android 5.0 themselves by following the instructions here.
