However, we have seen in progress in the form of an advanced shipping date that has moved from April 30th to April 23rd, seven days earlier than was originally thought. AT&T now says it will ship the Galaxy S4 on April 23rd. Still, the carrier has not released a specific release date for the Galaxy S4 which means we still aren’t sure if April 23rd is its release date or if it will be coming at a later date. Remember, we’ve heard April 24th and April 26th both rumored and we’ve seen AT&T customer service representatives say that the device will be coming out on May 3rd in stores.Advertisement Often, in-store release dates can be different from online release dates which means that AT&T could potentially offer the Galaxy S4 online starting April 23rd or April 24th and then release the phone in-stores later. At this point though it’s not clear.Advertisement Read: AT&T Galaxy S4 Release Date Undecided. The AT&T Galaxy S4 still doesn’t have a release date.
