By Monday midnight, Google started rolling out the 2nd developer preview of Android 8.1. This is, of course, the final preview and will be available for all Nexus and Pixel devices that got Oreo. That includes Nexus 5X, Nexus 6P, Pixel C, Pixel, Pixel XL, Pixel 2, and Pixel 2 XL.

The most notable change in this new preview is the activation of the Pixel Visual Core chip which was awaited for some time. If you don’t know already, the Pixel Visual Core chip is a dedicated chip in the Pixel 2, Pixel 2 XL that does image processing. The chip’s existence and function were only revealed after the launch of the two phones in October. The AI-harnessing chip though present on board wasn’t active and has now been activated for use.
For developers, this means that they can offer an experience like the default camera app itself and also offer HDR+ shots as well. This can be done using the Android Camera API.

Now, apart from this new capability, there are some bug fixes included as well. A known bug that plagued Pixel 2 devices was audio issues while recording videos. That has been fixed with the new update.

There was an audio issue specific to the Nexus 5X. Users reported no audio output with the phone speakers. This issue is fixed with DP2.

Another change is the Bluetooth battery indicator in dark mode. With DP1, it was only visible in regular mode. When switched to dark mode, the indicator wasn’t legible. With DP2 it is now visible.

Also, Google has warned that some apps might not play nice with the new preview and “may not function as expected.” This includes Google’s own apps as well. If you’re a part of the Android beta program, you should get an OTA soon enough. But if you’re not part of it, factory images can be found below as well as on Android Developer’s site.

Factory images for the new DP2 build are now live. We’ll leave a link to them below.
