You might recall that when the OG Apple iPhone launched (which was exactly eight years ago yesterday), YouTube videos were clear when rockin' a Wi-Fi connection. It was no surprise that on EDGE, most of YouTube was barely watchable.
Google has been constantly updating the YouTube experience. Those with a 1440 x 2560 QHD screen can view certain videos (like the Batman v. Superman trailer) in 1440p. Many say that they can't tell the difference between 1440p and 1080p. Either setting provides crisp, sharp entertainment for mobile device users.
YouTube now supports 60fps video for iOS and Android
