Android 5.0 Lollipop

Android 5.0.2 Lollipop released for Nexus 7 (2012) wi-fi

The latest version of Android has been updated again. Android 5.0.2 Lollipop (LRX22G) is available for the wi-fi model of the Nexus 7 (2012) and addresses issues affecting the performance of the tablet’s internal storage.

Currently, Android 5.0.2 Lollipop is only available for the one device. The issues that it fixes appear to be specific to the Nexus 7 (2012), so it is unclear whether this particular revision of Android will be adapted for other tablets and smartphones.

Performance of the Nexus 7 (2012) was prone to degrading, due to an issue relating to how files are written and deleted on the device’s internal storage.

This slow-down problem was originally fixed in Android 4.3 Jelly Bean, with the introduction of the fstrim utility. Fstrim ran without user intervention and ensured that there was minimal invalid data left on a device’s storage, meaning that files could be read and written faster.

[At the time of fstrim’s introduction, Android Wafer produced an in-depth guide, explaining the nature of the issue and how it was being fixed. You can read more about fstrim on the Nexus 7 (2012) here.]

Unfortunately, with the release of Android 5.0 Lollipop (LRX21P), fstrim failed to function properly for all users. This has been put right with the 5.0.2 (LRX22G) revision of Google’s mobile operating system.

The mobile data edition of the Nexus 7 (2012) is still running Android 4.4.4 KitKat (KTU84P), so has not been affected by the difficulty that has prevent fstrim from running. Owners of this device are still waiting to be updated to Lollipop.
