While Google didn’t unveil anything new for the Nexus 4, they did partner up with Samsung to announce the Galaxy S4 running stock Android 4.2 with a pure Nexus experience. As with every other Nexus device, updates will come directly from Google in a timely fashion in comparison to the staggered release from Samsung with their own TouchWiz interface.
The Galaxy S4 supports LTE, where the Nexus 4 doesn’t, however, it’s launching in the US only for now on the Play Store. There’s likely to be ways to go about getting it imported, so the price of $649 is going to be very compelling for a lot of people. The device becomes available on June 26th.
