Substantial leaks for the third-generation Made by Google devices emerged later than usual this year, with concrete rumors first surfacing at the end of May. In the coming months, there will be more and more rumors with one good source of news coming directly from Google’s Android Open Source Project.

9to5Google is compiling an updating list of when Google developers inadvertently slip up during the development process for these devices and the next version of Android. At the moment, we are aware of three codenames pegged with the Pixel 3 and Pixel 3 XL.

Last April, our Stephen Hall revealed a list of codenames for current Google projects. It included “sailfish” and “marlin” for the first-generation Pixel devices, as well as “walleye” and “taimen,” which are the Pixel 2 and Pixel 2 XL, respectively. “Muskie,” the shelved Pixel 2 XL from HTC, was also present.

Meanwhile, in October, a report suggested that “crosshatch” — now confirmed to be the larger XL device — and “blueline” from our list were like codenames for the Pixel 3. At the time, “albacore” was also offered as a possible codename for a third device.

Our full (reverse chronological) list of codenames referenced in AOSP will also provide some context to the nature of the entry:

blueline, crosshatch: July 19, 2018

Machine learning.

TensorFlow.

Machine learning.

Another direct reference to Blueline.

blueline, crosshatch: July 18, 2018

Related to machine learning.

blueline: July 17, 2018

Blueline is referenced directly in one entry by a Googler.

blueline, crosshatch: July 13, 2018

Another entry related to machine learning.

blueline, crosshatch: July 13, 2018

Another entry related to the camera.

blueline, crosshatch: July 11, 2018

The latest AOSP entry is in regards to the camera, specifically a “hot pixel model” and “shading mode.” Both likely try to address physical damage to the camera’s sensor that results in discoloration of a photo.

blueline, crosshatch: June 19, 2018

A new commit related to Neural Networks.

blueline, crosshatch: June 14, 2018

Two commits for blueline and crosshatch, again, in reference to machine learning, specifically TensorFlow.

blueline, crosshatch: June 12, 2018

A trio of commits (1, 2, 3) where both blueline and crosshatch are present in relation to machine learning frameworks.

blueline, crosshatch: June 8, 2018

This is the first commit where both blueline and crosshatch appear together. Given that the Pixel 3 XL is highly likely codenamed “crosshatch,” “blueline” is possibly the smaller Pixel 3 given the other mention a week earlier.

blueline: June 1, 2018

The first commit for blueline is in reference to testing done on that device of a “new spam API” for the phone dialer app that “can query additional data.”

crosshatch: January 11, 2018

Another entry related to development, crosshatch is referenced in regards to a Googler asking about the state of “LOCAL_MODULE_TAGS” and “adding it to device/google/crosshatch as a debug target.”

crosshatch: November 22, 2017

This commit wants to revert the earlier deletion of “toolbox/r.c” as “this utility is always useful during device bringup, so let’s bring it back for debug builds.”

Device bringup is a part of the development process where a system is repeatedly tested, validated, and debugged until it is ready for manufacturing.

In this case, one Googler notes that the tool is used “a lot” as part of crosshatch development.

crosshatch: October 26, 2017

The first reference for crosshatch in AOSP is in regards to an “audio subsystem” related to the “Pixel and Qualcomm.”
