Google testing revised Pixel launcher that features one change to the search bar
New version of Pixel launcher replaces the microphone icon with the icon for Google Assistant
The version of the launcher that is being tested by Google (seen in the screenshot at right) is 9-4889482. The current, publicly available version of the Pixel launcher available online is 9-4836503. The revised launcher APK was taken from the official Android Pie image for Android Studio Emulator. However, Google signed it using a different signing key than the one it used on the publicly available version of Pixel launcher. That means that if you come across the new APK and decide to sideload it on your device, the new launcher will not install over the current launcher used on your handset.
When the Pixel 2 XL launched last October with an aspect ratio of 18:9, Google decided to move the search bar to the bottom of the screen. The rainbow-colored "G" insignia was found on the left of the search bar with the microphone icon on right.
