Samsung Electronics now has a trio of co-CEOs after adding presidents Yoon Boo-keun and JK Shin to the executive team. They join Samsung’s current vice chairman and CEO Kwon Oh-hyun and will server alongside COO and president Lee Jae-yong.

The move comes a day after Samsung unveiled its Galaxy S4 at an event in New York City’s Radio City Music Hall.

Amazon Wireless has been slashing prices on Samsung’s popular Galaxy S III and Galaxy Note II devices following the unveiling of the Galaxy S4 on Thursday evening. Available through Verizon, AT&T, and Sprint, the Galaxy S III is now on sale for just a penny, while the Galaxy Note II can be picked up for $69.99 — that’s more than $500 off its regular retail price.

Gameloft’s Modern Combat 4: Zero Hour is, without doubt, the best first-person shooter available on mobile. It’s the latest edition to the company’s Modern Combat series, and it promises to “push the boundaries of mobile gaming even further” with stunning visuals, an awesome campaign, and a completely redesigned multiplayer mode.

If you haven’t already got it and you’re a fan of FPS titles, then you’re crazy. But now’s the best time to pick it up, because its price tag has just been slashed from $6.99 to $0.99 for a limited time.

Good looking, but cheap.

After months of rumor and speculation surrounding the new Galaxy S4, Samsung finally unveiled its new “life companion” at a very peculiar event in New York City’s Radio City Music Hall last night. The device has already received some criticism for looking a lot like its predecessor, the Galaxy S III, and indeed a number of Samsung’s other smartphones.

Fans are disappointed that the Korean company has continued to use plastic for its new flagship — despite a company executive explaining the decision behind this earlier this month — and that it hasn’t switched to more premium materials like aluminum and glass, following companies like Apple, HTC, and LG.

If you’re one of those fans, then you’re going to be even more disappointed when you hear the latest Galaxy S4 rumor, which claims Samsung developed a number of prototypes for the device, then brought the cheapest one to market.

At one point during Samsung’s tacky Galaxy SIV launch event at the Radio City Music Hall in New York, the emcee — upon asking what the point of a screen that could react to gestures in mid-air without actually touching it, and being treated to a Greek chorus of answers from a constabulary of shrill, histrionic shrews — said of Samsungs new Air Gestures: “Okay, I see how that might be useful.”

Those words really sum up everything Samsung put up on stage tonight. I see how that might be useful.

The Galaxy SIV is a phone largely unchanged from the SIII. It’s a little thinner, a little lighter, a little more powerful. It has a bunch of new features. And all of them require a small one-act play on one of the most important stages in Manhattan to explain why, in a certain circumstance, they might be useful.
