Google released the final version of the Android 8.1 Oreo with Developer Preview 2 which is termed as the last update of the 8.1 series. We have already seen the first preview of the 8.1 Oreo with build (OPP5.170921.005) from Google which brings a new API 27 and several new features on top of the 8.0 Oreo. The final Developer Preview brings the new build version OPP6.171019.012. The factory images are now available for download and if you are on the previous Developer Preview build 1, then you will most likely receive the OTA notification.

The 8.1 Oreo Developer Preview comes with a new firmware build number OPP6.171019.012 for the Pixel 2, Pixel 2 XL, first generation Pixel, Pixel XL, Pixel C, Nexus 6P, and the Nexus 5X. Being a preview build, it is still in it Beta stage. However, by reports from several users of the preview, the firmware is quite stable and can be used as a daily driver.

When do we get the stable Android 8.1 Oreo?

So, as Google has started the final Developer Preview rollout, we should expect the stable one to show up as soon as next month. The stable 8.1 Oreo build will come next month featuring the December 2017 security patch.

Moreover, users on 8.0 Oreo or 7.1 Nougat will continue receiving the December 3, 2017, security patch as well.

What’s new with Android 8.1 Oreo Developer Preview 2? The update is basically targeted towards Android developers and app developers. As it comes with a new API v27, Google is requesting app developers to update their applications on Play Store by the end of December. This will assure seamless transition of apps to the new OS. Apart from that, you will see several bug fixes present in the previous updates.

The previous preview brought:

  • Android Go memory optimizations and targeting

How to flash Android 8.1 Oreo onto Google Pixel and Nexus phones?

1) The installation is simple, if your device is on the previous 8.1 Oreo DP 1, then you will receive an OTA update. All you need to do is check for any OTA updates from settings.

2) If your device is on the stable 8.0 Oreo update, then to get the final Developer Preview, you need to enroll in the Android Beta Program. Once enrolled, you’ll receive an update in the next few hours. Note that only a select few Nexus and Google devices are eligible for the Android Beta Program.

3) Lastly, you can simply download the Android 8.1 Oreo Developer Preview 2 factory image and flash using the fastboot mode. This is helpful when you have rooted your device and installed a custom TWRP recovery. When you have custom packages installed you lose the ability to receive and install OTA updates and install them using the recovery. So using the factory images, you can restore your device back to stock.
