Google Now Launcher that went official with the Nexus 5 is now officially available to all Nexus devices and Google Play Edition devices officially. The launcher which was exclusive only to Nexus 5 can also be installed on other Android devices by simply sideloading the APK on the device.
This week, Google rolled out Google Now Launcher to the Play store but making it available for install only on Nexus and Google Play Edition devices. The APK was pulled from the Play Store and found working on all Android phones running Google search version 18.104.22.1689776 which is the latest update to the app.
As soon as the APK was posted on XDA Forums, I gave it a try on my Moto G running Android 4.4.2 and it seems to work well without any lags or redraws.
In case you wish to give the launcher a try, download the APK and install it on your device using any file manager. Make sure “unknown sources” is checked in your device’s security settings.
