Google has released the December update for Android Lollipop and Marshmallow, holding true to their monthly security updates to the mobile platform. The new images for Nexus devices has been released for OTA updates as well as factory images and for Marshmallow, it will be known as 6.0.1. If you have a Nexus device, you can expect to start seeing the update over the next couple of days unless you are locked to a carrier in which case it will be a bit longer.
The update contains no less than 16 vulnerability fixes, the most severe of which allowed for remote code execution.
The most severe of these issues is a Critical security vulnerability that could enable remote code execution on an affected device through multiple methods such as email, web browsing, and MMS when processing media files.
In all there were 4 critical issues addressed along with 10 high risk issues and 2 moderate risk issues.
Android Update Has New Camera Function and Other Tweaks
While the update is primarily focused on security fixes, there are a few new features and UI tweaks in this release as well. Perhaps the biggest news last week in a leak was a new set of emoji which has come to bare while there is also a
new camera shortcut that allows you to start the camera app even with the device off by double-tapping the power button on your device. This will allow you to take that quick shot without having to go through the process of unlocking your phone or even swiping the right corner to take a photo.
There is also an improved alarms function where you can setup Do Not Disturb until next alarm function. This was actually there on some devices in the past but now has been re-introduced and is available on all devices.
As to when you will receive this update is largely dependent on when Google rolls it out to your unlocked device. That is starting now but could be up to a few weeks before you see it. If you are locked to a particular carrier like AT&T or T-Mobile, the wait could be substantially longer.
