No software ever ships without bugs, especially on the first release. That is true for games, operating systems, or even something as simple as an Android home screen launcher. So when the Galaxy S8 and S8+ launched with a less than smooth UI experience, users were naturally miffed but also a bit patient for an update. That update has now arrived and Samsung has updated its TouchWiz Home launcher that promises to fix that lag bug. Some users, however, are reporting otherwise.
