The iPhone 5s remains No. 1, as the Samsung Galaxy S IV improves to No. 2.

For the first time this year, Samsung bests Apple in terms of U.S. phone sales, at least according to one survey.

Samsung has launched a gold iPhone of its own in the United Arab Emirates.

Now we know why Samsung continues to bash Apple in ads. It works.

Apple is continuing to maintain its share of the U.S. smartphone market following the launch of Samsung's Galaxy S4.

With the next-generation iPhone not expected to be introduced until the fall, does Samsung have a temporary opening to gain on Apple?

Samsung says it sold 6 million Galaxy S IV smartphones during the first two weeks of release.

While Apple's latest iPhone 5 TV ad quietly tugs at people's heartstrings, Samsung's latest Galaxy S4 TV ad decidedly pokes fun at the iPhone itself.

Samsung's newest smartphone is easy to break, when compared to the company's previous model, and the iPhone 5.

Samsung's next handset is likely to arrive at AT&T first, followed by T-Mobile, and Verizon.

The next iPhone could be fast - like, really fast.

Apple has gone out to remind the mobile world that the iPhone is still the best handset around.

As expected, Samsung has just "unboxed" its new flagship smartphone, the Galaxy S IV.
