Even though the Galaxy S8 and S8+ are only just now being released to the public, the software leaks have been rolling in for a while. Everyone seems to have gone crazy for the new look Samsung is pushing out with Samsung Experience, the successor to TouchWiz.

A few months ago, LlabTooFeR leaked a full system dump from Google's then-unreleased Pixel and Pixel XL smartphones. That may not seem like a big deal at first glance, but the system dump contained all of the preinstalled apps and services from Google's new flagships—including the much-anticipated Google Assistant.
