Currently, a beta version of the Android O is available for download on a few of the Google devices, these being the Nexus 5X, Nexus 6P, Google Pixel, Google Pixel XL, Pixel C tablet, and Nexus Player. The aim of this preview is to help the developers continue working on the Operating system and to have the OS ready for launch. The preview will give the devs more time to ensure that all the applications will be compatible with the future release version. There are also rumors that Google will soon be releasing the second version of the developer preview build at the Google I/O conference.
While we do not know what the next iteration of the beta will have in store for us, you can currently download and try the current developer preview version on the compatible devices. It does have a few neat new features, but it should be known that it’s not a finished product and there are significant issues with it that can affect your experience with your device. It is also generally recommended that you make back-ups of your data before switching to this testing build, as reverting back will cause all data to be deleted.
To begin with, you will need to enroll in the Beta Program that Google has made for the Android O. This is done by accessing the g.co/androidbeta website and logging in with a Google account. Afterwards, you will want to scroll down the page and search for the Enroll device button on the compatible device you are trying to install it in. Once tapped, you will have to tap on the Join Beta button and it should be clear afterwards what it is you must do to continue.
