PCMag spoke with Nick DiCarlo, Samsung's vice president of portfolio planning, at tonight's event, and he said that many of the software improvements in the Samsung Galaxy S4 could make their way into existing Samsung Galaxy S3 phones.
"Anything that we can do that's not dependent on hardware like infrared, we'll definitely bring to all the flagship devices," he said.
That may include the Galaxy S4's new camera features, which DiCarlo said several times were a highlight of the new phone. When asked why Samsung picked a 13-megapixel camera sensor rather than going for bigger pixels like HTC did, he said the new UI was more important.
"The key thing you've got to think about in this debate is, how easy is a camera to use and what cool things can you do with it?" he said. "Photo quality is great, and has been great; for the average person the day-to-day person you're not having a quality argument about photography. For your everyday use case, the ability to remove photobombers and that kind of stuff is really what's going to have people talking."
When asked about what he considers the "wow" features on the S4, DiCarlo called out the camera UI, the WatchNow TV remote and gesture control, but also how Samsung made the device's screen bigger while the phone is physically smaller than the Galaxy S3.
