How to Manually Install Android O Developer Preview

Google has official announced its next update for its Operating System (OS) on March 21st. The company has unveiled the first developer builds for the next major update to Android. The Nougat successor, Android 8, dubbed as Android O.

In the announcement, Google released factory images for the first developer preview of the upcoming update.

Android O primarily will be focusing on better battery life and notifications. Google is not offering the O preview as part of the Android Beta program as of now.

Why doesn’t Android O release for Beta Program?

Earliest builds will have many things broken and packed with bugs, glitches. It is released for developers and not intended for daily or consumer use. This means the preview is probably not stable enough to be run on your main device.

When will Android O open up for Beta users?

When things are ready for regular users, Google will open up O for the Android Beta users.

If you still want to try it out, then you will need to manually install it; if O is compatible with your device.

Compatible Devices:

Like always the preview will only be work with selective devices. The Android O developer preview image is for the below-mentioned devices.

Pixel Devices – Pixel XL, Pixel and Pixel C.
Nexus Devices – Nexus 6P, Nexus 5X, and Nexus Player.

Any other Nexus or another brand devices will not support Android O.

Now before you jump and get ready to update. This process is not as easy as downloading an OTA, so you could also end up with a bricked device.
