On the day of the release of the first test assembly of Android P enthusiasts ported Pixel Launcher from the new firmware to all devices. It is noted that the home screen of Android P has undergone only a few changes in comparison with the previous version: the docking panel Pixel Launcher became opaque and got more rounded edges. You can try the updated application right now by installing the APK file.
The port authors claim that they did not change the application components, but removed the authentication and re-signed the APK-file. Before installing the package, you must uninstall the previous version of Pixel Launcher.
It is reported that the launcher from Android P is compatible with the utility Pixel Launcher Mods to change the icons and badges of notifications on devices with superuser rights.
