Eye-tracking tech in the Samsung Galaxy S4? Say what?

If the Samsung Galaxy S4 rumors pan out, Samsung's newest smartphone may let people interact with the screen using just their eyes.

Join CNET on Thursday, March 14 at 3 p.m. PT / 6 p.m. ET for live coverage of the Samsung Galaxy S4 event

Eye-tracking uses the camera to lock onto the motion of a user's peepers, following wherever they move. With it, the phone can perceive where the user is looking, and can respond to a set of behaviors, let's say a very intentional movement to scroll a Web page up and down, or … Read more

How to sell your phone for cash (Smartphones Unlocked)

In last month's Smartphones Unlocked, I shared what happens to your smartphone when it ceases to be yours.

Although I listed resources for getting rid of your phone (and took a poll of what CNET readers usually do with their old handsets,) it's high time I offered up some tips for how to go about selling your phone...or any other consumer electronic, for that matter.

Don't count on a Hawaiian vacation for your efforts, but depending on how much you hoard or how savvy you sell, the dollars could really add up.

Android 4.1 Jelly Bean will begin rolling onto Verizon's Samsung Galaxy S3 as soon as tomorrow, Verizon announced today on its blog.

Security risk at the root of a rooted Samsung Galaxy S3

For all the flexibility that comes with rooting an Android smartphone, there are always intrinsic risks. Such is the case with at least one Samsung Galaxy S3. A moderator over at XDA forums recently discovered that his handset was storing his Google account password in clear text in the S-Memo application.

While this isn't so much of an issue for nonrooted Galaxy S3 users, it's worth a reminder that rooting could give novices more than they bargained for. Not all developers are trustworthy, not all custom ROMs are stable and secure, and you do put yourself at risk … Read more

iOS 6.0.1 already jailbroken -- for some devices

iOS 6.0.1 users can now jailbreak their devices, but there are some bumps in the road.

The latest version of the iPhone Dev Team's Redsn0w can jailbreak iOS 6.0.1 devices, Redmond Pie confirmed today after testing the update.

However, not everyone can take advantage of the effort at this point.

The jailbreak works only on iOS devices powered by an A4 chip or lower. People who own the iPhone 5, the newest iPads, or the latest iPod Touch are out of luck. The jailbreak takes advantage of the Limera1n exploit, which can't handle the … Read more

Mini Galaxy S3 evidence piling up before Samsung event

Looks like "mini" is going to be in this holiday season. There's more reason to believe today that Samsung is going to be introducing a smaller version of its blockbuster Galaxy S3 Android phone later this week.

Samsung sent out an invite for an October 11 event that says something about small being big or some other clever, oxymoronic and mysterious marketing speech, depending on which translation app you use. … Read more

Apple can replace broken iPhone 5 screens in the store, says report

iPhone 5 users who suffer a broken or scratched screen may be able to get a replacement directly in the store, according to a report from iMore.

Citing "sources within Apple retail," the blog site said that the equipment used to replace iPhone screens has started showing up in the stores themselves. This move means that Apple store reps could outfit an iPhone 5 with a new screen on the spot rather than switching the entire phone for a new or refurbished model.

The screen swap-out process for the new iPhone would match that of the iPhone 3G … Read more

Apple's Siri trounces Samsung's S Voice (hands-on)

I've updated this hands-on to reflect Siri's new tricks in iOS6; it originally posted June 21, 2012 comparing S Voice on the Galaxy S3 -- which is still current -- to Siri on iOS 5. If you're wondering, tomorrow I'll be comparing the updated Siri to Google Voice Actions.

Voice assistants like Siri, S Voice, Google Actions, and Microsoft's TellMe aren't new, but they are evolving into more mainstream features that can expedite results. S Voice, which launched this summer on the Samsung Galaxy S3, is Samsung's answer to Siri. That also makes … Read more
