Google's latest Android update, 5.0 Lollipop, has created a ton of problems for many Nexus device users. While Google went ahead and patched some of them in Android 5.0.1, bugs still plague the firmware. Luckily for owners of the 2012 Wi-Fi-only Nexus 7 tablet, there's now an Android 5.0.2 update available.

Most 2012 Wi-Fi-only Nexus 7 tablet owners will have to manually download the Android 5.0.2 (LRX22G) "nakasi" update via Google's developer site. This also involves manually installing it, and for those not familiar with flashing their Android devices, it's probably best to wait given the possibility of bricking the device. The update has been confirmed to be rolling out over-the-air, although it seems the rollout seems to be going extremely slow as only a handful of users have reported in that they've gotten the download notification.

Details about what exactly Android 5.0.2 brings to the table are scant, but overall it seems that it does improve some of the stability problems that 5.0 Lollipop brought and brings a slight boost to performance. Of course, like any new firmware, it brings its own set of problems to the table, such as battery issues, sound issues, and Wi-Fi connectivity, but it is still a step up from the previous versions.

Oddly enough, the 2012 Wi-Fi-only Nexus 7 tablet is currently the only one with an Android 5.0.2 file for download. The Nexus 4, Nexus 5, Nexus 6, 2013 Nexus 7 models, Nexus 9 and Nexus 10 all do have an update available past Android 5.0 Lollipop, except that it's only Android 5.0.1. There's no word on whether these devices will receive Android 5.0.2, or if Google will simply wait for Android 5.1, rumored to release sometime in February, before updating them. Even stranger is the 2012 3G Nexus 7's predicament -- the tablet is still stuck on Android 4.4.4 KitKat.

The reason for the discrepancy in Android versions across Android devices lies in Android's open source nature. Google initially develops the new code and releases it to the public and, usually soon after, to the Nexus brand of devices since they run stock Android. Other companies, like Samsung and HTC, however, then take the time to tailor the code to fit their devices, often layering their own interfaces on top (Samsung's is TouchWiz and HTC's is Sense). If the devices are tied into carriers, consumers then have to wait even longer as the networks then usually add in some of their own software tweaks before approving and pushing them out.
