Well, it’s another month (Happy February!) so another security update from Google. The February security update factory images for Nexus devices have been posted by Google, and you can check those out and flash them to your Nexus device by going to the Google Developers website.
The update is Android 6.0.1, and we are looking at build MMB29Q for the Nexus 6P, 5X, 6, 5, and Nexus 7 , MMB29R for the Nexus 9, MXB48T for the Pixel C, and MMB29U for the Nexus Player. The Nexus 10 is also receiving build LMY49G of Android 5.1.1 Lollipop.
Expect to see the build hitting devices over the next couple of days via OTA.
Update (2/1/16, 7:32PM EST): The security fixes for the update have been posted on the Android website. The changes are also listed below.
