We recommend trying the wallpapers first, then going on to the launcher if the wallpapers aren't enough to tide your need for Pixel 2 over until the devices are released.
You can install the Pixel 2 launcher apk file from the download link below and install it like you'd install any other apk file on your device.
The Google Pixel 2 was recently said to have the best smartphone camera now available, according to DxOMark. If you have a Nexus 5 or newer device, however, you'll be able to grab it. However, most everything else, including App Shortcuts and the new "at a glance" widget, seems to be working as it should. Download these new apps from below. It also shows the weather only when location is turned ON. The feature can be toggled on and off. The widget at the top displays your upcoming events or reminders from your Google Calendar. The Google Search bar is persistent throughout every homescreen though. The Pixel 2 models will be here in just a few days time, but as is tradition, the folks over at XDA have already got the new launcher ripped and ready to be installed on most Android phones out there.
If you are curious about what's so fancy about it, well, the search bar has been moved to what may be an awkward position for some (all the way at the bottom), but other than that, it's a pretty straightforward launcher.
We aren't sure what took Google so long to make this feature available, but either way, we're thrilled that it's finally here to use.
