What’s worse than smudgy fingerprints on your phone’s screen? Well, a lot of things (bears with sword hands), but it is still annoying. With the Samsung Galaxy S4, those are a thing of the past (sort of). Smart Scroll allows the device to detect when someone is looking at it, and then scrolls the screen based on the angle it is tilted at and when the user waves their hand over it. Another feature that’s pretty neat is the phone’s Dual Camera technology, which lets you take a photo with both cameras simultaneously. The images from the rear and front-facing cameras will appear in one shot. The Galaxy S4, which comes out in April, will have a 5″ full HD display, 2GBs of RAM, and 4G LTE connectivity. It won’t convert every iPhone user, but it should steal a few Apple fans.
