By Chris Smith March 16, 2013 42 20 56 2 The Galaxy S4 will launch in a variety of markets by the end of April, and hopefully U.S. carriers will get the handset at the same time. For now, we only have a release date for UK’s Everything Everywhere, which will have the handset out in the wild on April 26.Advertisement We wouldn’t be surprised to see more European and other international mobile operators kick off the Galaxy S4 launch party around the same date, but it would definitely be interesting to see how U.S. carriers will play it out. Will the handset launch simultaneously in the U.S. and Europe? Six American operators have already been confirmed to have the Galaxy S4 in stock later this year including Verizon, AT&T, Sprint, T-Mobile, U.S. Cellular and Cricket Wireless. Of those two, AT&T and T-Mobile have already put up Galaxy S4 sign-up pages that don’t reveal that many details. You know the drill, all you have to do is fill in a form and you’ll be notified the moment either carrier has Galaxy S4 information for you. Interestingly, each mobile operator has its own way of teasing the handset, with AT&T showing an empty box, while T-Mobile displays a Galaxy S4 teaser image even though the handset has been announced. AT&T tells us that the secret is out and lists three Galaxy S4 features, Smart Scroll, which sounds better on paper than it did in Samsung’s presentation, WatchOn and the camera features: Scroll through a page using just your eyes. Turn your phone into a TV remote control. Take photos you’ll never believe came from a smartphone. T-Mobile is insisting on the same features, although it sort of adds Air Gesture to the mix, without naming the feature: DO SOMETHING YOU’VE NEVER DONE BEFORE Take photos so amazing, you won’t believe they came from a smartphone. Turn your phone into a TV remote control. Navigate your screen without even touching it. In case you have no idea what Smart Scroll, WatchOn or Air Gesture are, check out this list of software features for the handset. Will you buy the U.S. Galaxy S4 version?
