Get the Android O beta download here
The first day of I/O was very fruitful for Google, as the search giant had quite a few announcements for Android fans. Android Go, Expeditions, Smart Reply for Gmail are just some of the new stuff that we've already reported about recently, but we're expecting new announcements later today.
For those who can't wait for the final Android O release, Google had something else prepared. An updated version of Android O Developer Preview is now available for download.
If you've already installed the first Android O Dev Preview, then the OTA image should be automatically delivered to you in the next few days. Otherwise, you will have to register to participate in the Android O Beta Program so that you can flash the Android O Developer Preview 2 on your device. You can subscribe for the beta program here.
Keep in mind though that this Android O build will only work on the following devices:
One more thing that's worth mentioning is that Google has already released the factory images and OTA files for Android O Developer Preview 2, so you can go ahead and download them rather than wait for the update to arrive.
