The Android 7.1.2 Nougat beta 2 build brings the Pixel Launcher to the Pixel C tablet, which is the launcher that launched with the Pixel and Pixel XL last Fall. If you have a Pixel C tablet the Pixel Launcher is just one of the handful of changes that looks like are making their way to the tablet, and since the update just started hitting compatible devices this morning, chances are that some users will see the update hit their Pixel C today but it may not show up until later on this week.
As the Pixel Launcher becomes part of the Pixel C tablet, the navigation buttons from the Pixel launcher will become available as well. Other familiar elements to the Pixel launcher will be present and immediately noticeable following the installation of the latest beta, like being able to swipe inward from the left edge of the main home screen to access Google Now, as well as swiping up from the bottom edge of the main home screen to access the app drawer. This also includes the round app icons and the new style for folders.
While most of the Pixel Launcher-related changes that can be seen on the Pixel C are the same as you'll find on both the Pixel and Pixel XL, there are some differences here. For example the Pixel C has a different looking multi-tasking UI than what can be found on the pixel and Pixel XL. As opposed to having a stack of scrollable cards, all of the cards are presented next to each other in rows and columns, though there is no explanation if this is just in landscape mode or if it also appears this way while in portrait mode. So far that seems to be most of the changes that are included with this beta that are new to the Pixel C, though more may show up as more people have had time with the software. Google began sending out the latest Android 7.1.2 Nougat beta earlier this morning to the Pixel and Pixel XL, the Nexus 5X, the Nexus 6P, and the Nexus Player in addition to the Pixel C tablet.
