Google has now turned the wick up on the Android N Beta Program site, allowing you to register your device and download the next generation of Android to your eligible device. The program is designed for developers to download the technical previews as they are released via an OTA update instead of having to reflash your device each time, a huge time saver to say the least.
When you sign into the site with your Google account, your eligible devices will be listed and you can enroll that device into the program. Shortly thereafter you will see an OTA update to Android N come to your device and you can start using it. The download is a typically big download, about 850MB, so you will have to be on Wi-Fi to
A couple of things to consider: First, although this makes it super easy to get Android N on your device, it is really intended for developers. As I put in my post announcing the preview’s availability, this build is the first and it is going to have issues so don’t download it and install it on your main phone or tablet.
Second, if you decide to make the jump and then decide it is not for you, downgrading back to Android Marshmallow will completely wipe your device.
You may opt-out of the program at any time to return to the stable, public version of Android. Note: If you opt-out when your device is running a beta version of Android, all user data on the device will be wiped.
The warning is clear folks so proceed with caution. It is beta.
