Samsung Galaxy S4 features coming to S3

You don't need to buy the Samsung Galaxy S4 to benefit from its new features, as many are headed for the current Galaxy S3.

The Samsung Galaxy S4 is packed with new features -- but you don't need to buy the new phone to benefit, as many new features are headed for the Samsung Galaxy S3.

Speaking to PCMag, Samsung promised that the S3 and other phones and tablets will get new software features announced on the S4 last week.

"Anything that we can do that's not dependent on hardware like infrared," says Samsung, "we'll definitely bring to all the flagship devices."

Samsung boss Nick DiCarlo highlights the camera interface and WatchNow TV remote. While the camera interface doesn't rely on hardware only found in the S4, and should therefore trickle down to other devices, the remote control uses the S4's built-in infrared blaster and so can't come to the S3.

New features on the S4 that could translate to the S3 -- or the Galaxy Note 2 and other current devices -- include real-time lingo-decoder S Translator, and an array of pointless camera features, such as Dual Camera pictures.

Some features look like they could make the switch but might rely on hardware in the S4's camera. I'm talking about the various hands-off features that let you control the phone without touching the screen, as the camera detects your hand waving in front of the screen to scroll and swipe, your eyes straying from the display to pause a video with Smart Stay, and your hand tilting the phone to Smart Scroll.

The S4 has drawn some stick for not marking enough of a change over the S3. Check out our guide to the best and worst bits of the S4 and CNET readers' reactions to the new phone. And hit play on the video below to see the S4 compared to the S3.

There's no word yet on when the S4's software features will come to existing phones, but I'm guessing Samsung will keep them to the S4 for a while to entice you to buy its newest blower.
