With the Android N developer preview out, Google has also launched a new Android Beta page for developers or even curious users to try out Android Beta Program and get OTA updates for Android N. Currently, the beta is open to users with a Nexus 6, Nexus 9, Nexus 5X, Nexus 6P, Nexus Player, and Pixel C. It's being reported that even Android One phones might be added into the mix in the future.
If you sign up for the program, it's said you'll get the update up to 24 hours after they're released. Of course, we have to warn you that these are unstable Android builds being installed into your device so might want to hold off using your main phone for this one.
