Google is stomping on some bugs in short measure after its major Lollipop release.
There are no specific release notes for the Android 5.0.1 release, but don't expect any major new features. Instead, this appears to address a couple of relatively minor bugs. If you are impatient and know how to flash a factory image, you can grab it from Google right now. The build (LRX22C) is available for the Nexus 9, 10, and 7 (2013 model). Factory images for other models are expected soon.
The newest version of Android also has been pushed to the Android Open Source Project, so hardware makers can incorporate it into their own Android builds.
Google hasn’t posted any specific details about what exactly this fixes, but evidence points to a fix for a bug that could automatically factory reset your device after too many failed entry attempts.
For example, Android appears to be too sensitive at registering unlock attempts for those using the pattern security screen. Android may mistake any kind of screen interaction as a failed unlock attempt, such as if something rubbed against the screen in a purse or pocket. With too many failed attempts, it will automatically reset the phone or tablet.
To fix this, Android now requires sliding across at least four dots to register an attempt, which your keys or wallet are unlikely to do.
The 5.0.1 update also should kill off a problem that causes video playback to fail, a bug noted on the Google Developers site.
The rumor mill is also been buzzing about Android Wear getting its own watch-sized version of Lollipop timed with this update, but there's no sign of that yet.
Why this matters: Smaller, bug-fix updates are the norm after a major operating system release. Android Lollipop is a substantial revamp, so some bugs are bound to be discovered as it hits more devices. The small rollout that’s starting with Nexus devices should help avert the disaster that befell Apple with its iOS 8.0.1 update.
