After issuing a quick update to build MPA44I (well, new images) that followed the initial release of the Android 6.0 Marshmallow Developer Preview 3, Google is now starting to roll updates out over-the-air (OTA) to compatible Nexus devices. We have a running list of the .zip Preview 3 OTA updates for your Nexus 5, Nexus 6, Nexus 9, and Nexus Player (soon) below, in case you either didn’t get prompted to update your device or didn’t feel like messing with the factory image files. We’ll update this as we have more.
