Recently, we got to know about the Pixel Visual Core chip, which is inside Pixel 2 and Pixel 2 XL. And which was supposed to enabled when Android 8.1 Developer Preview 1 dropped. But, when developer tried to look for it, they were unable to do so and realized that Google had neglected to enable it for the public preview. Now, Google has updated its documents, which says Pixel Visual Core will be enabled in 8.1 Developer Preview 2.
Ron Amadeo of Arstechnica, recorded a video in which he attempts to enable the Pixel Visual Core and fails by following the exact steps that Google had provided, Ron was unable to even yield the 'Camera HAL HDR+' option that should show up in Developer options.
Folks at XDA Developers dug some information and found that Google had inadvertently made the option only accessible on debug or engineering builds. There's supposed to be a switch you can toggle if some checks are met, but some of these just can't be achieved by consumer Pixel 2 devices right now. The phone will first check against a boolean value called “config_show_camera_hal_hdrplus,” an option that is satisfied by all Pixel 2s. But when it checks against a system property called “ro.build.type,” if “userdebug” or “eng” (debugging or engineering builds' strings) can't be matched, Visual Core will remain stagnant. Another check your phone will fail is “persist.camera.hdrplus.enable,” which can't be done without root access, of which there is currently none for the Pixel 2 line.
Google has since updated its release notes to show that the functionality will be arriving with Android 8.1 Developer Preview 2. So for those of you who were hoping to have a look at Pixel Visual Core, you'll just have to wait a little bit longer.
