After rolling out the first fixes for Android Lollipop on Nexus phones and tablets, Google has tied up some loose ends with a separate update just for the 2012 Nexus 7.
The 2012 edition of the wi-fi-only Nexus 7 wasn't included in the 5.0.1 release that arrived for other Nexus family members over the past month. So far, the Nexus 4, Nexus 5, Nexus 6, Nexus 9 LTE and wi-fi versions, Nexus 7 2013 wi-fi version, and Nexus 10 have all been bumped up to 5.0.1 through an update with the build version number LRX22C. The Nexus 7 2012 wi-fi edition, however, is getting the 5.0.2 update with the build number LRX22G.
As Android Police noted with Google's release of the the factory image for 5.0.2 last Friday, the update may be exclusive to the 2012 Nexus 7. Notably, the mobile editions of Nexus 7 2012 and 2013 remain on KitKat.
Google hasn't provided any detail about what's in the 5.0.2 update, however Funky Android has posted a changelog of differences between LRX22C to LRX22G.
The list includes four changes for the 2012 wifi Nexus but also two for devices codenamed 'Tilapia', which is the Nexus 7 2012 mobile edition. This suggests there may be updates of some kind in the works for that device but whether it's a Lollipop update remains to be seen. Android Police noted the changes for both devices make performance enhancements through tweaking the kernel.
Android 5.0.2 contains two main updates, with one fixing storage performance and several others addressing bugs in AlarmManager, a service in Android that allows developers to schedule their apps to run at a certain time even their app is not currently running. The fixes address how those alarms behave when scheduling tasks.
