We expect to see the phone introduced at the Samsung Premiere event scheduled for the U.K. on June 20th. Look at the photograph below. Note how the date on the phone screen shows the very next day, June 21st, which could mean that the phone will be ready for launch immediately after it is unveiled. In all honesty though, screenshot dates have been an iffy proposition when forecasting a release date.
Along with the Samsung Galaxy S4 Active, at the Premiere event we should see the Samsung Galaxy S4 Zoom with the 16MP rear shooter and the 10X optical zoom, and the Samsung Galaxy S4 mini.
