Samsung last month launched its latest smartphone--the Galaxy S III, which features a 4.8-inch super AMOLED screen (with a resolution of 1280 pixels by 720 pixels), a quad-core processor, 1GB of RAM, and an 8MP camera. The phone also has NFC technology built in, and contains a MicroSD card slot that allows users to expand the memory.

Interest in this phone runs high across the Internet.

The Wordpress blog Inside Sprint Now Tuesday leaked 15 Samsung Galaxy S III training videos. Inside Sprint Now is allegedly authored by an anonymous Sprint/Nextel customer service rep. However, a Samsung PR rep told PCWorld Tuesday evening: "These videos are not associated with Samsung, and Samsung does not comment on rumors or speculation."

The videos mostly demonstrate features we've already heard about--such as S Beam, which is an enhanced version of Android Beam, and the zero shutter lag camera with Burst Mode.

One video demonstrates "Smart Gestures," which let you set up special movements that allow you to better interact with your phone--such as "Direct Call," which lets you pick up the phone while texting to dial the number of the contact you're messaging. Take a look:

However, one video demos a new feature we haven't seen before: Samsung TecTiles. According to the video, TecTiles appear to be NFC-enabled stickers that let you tap your phone against them and automatically perform preset functions.

You can apparently set up the functions and link them to a TecTile sticker, and then stick the TecTile in your house, in your car, or on your desk so as to be able to immediately access those functions by tapping your phone against the sticker.

The Galaxy S III is slated to debut in North America this summer, though the U.S. version of the phone will not have the quad-core Samsung Exynos processor. The Galaxy S III will be offered by AT&T, Sprint, T-Mobile, Verizon, and U.S. Cellular.

S Voice: Samsung's Siri

Another video demonstrates S Voice, which is Samsung's response to Apple's voice-activated personal assistant, Siri. According to the video, S Voice can adapt to your individual preferences and "get to know you" over time.

Other goodies you can check out in the videos include the ShareShot feature (which lets you share photos instantly over a Wi-Fi network), a lockscreen from which you can access various apps, and a slide-sharing feature called All Share Group Cast.

At the time of this posting, Sprint had not responded to our request for comment.
