Samsung has confirmed it will announce the much-anticipated Galaxy S IV at a public launch event in New York City’s Times Square on March 14, but until then, the details surrounding the handset’s design and specifications remain a mystery.

Recent reports have offered hints at what the new device may offer, and according to the latest, there will be two versions — one powered by Qualcomm’s quad-core Snapdragon 600 processor, and one powered by Samsung’s eight-core Exynos 5 Octa chip. But why do we need two?

Google is said to be preparing a second-generation Nexus 10 tablet for Mobile World Congress in Barcelona next month. The device will reportedly offer a quad-core processor and faster graphics, making it a significant improvement over its predecessor — which was only launched last November.

Samsung has produced some of the most popular Android-powered smartphones in recent years, and its flagship Galaxy S III has been one of the most successful devices of the past 12 months. But just how successful are they? Well, Samsung announced on Monday that it has now sold more than 100 million smartphones from its Galaxy S series, with more than 40 million Galaxy S III units shipped in just seven months.

Developers have discovered a serious vulnerability with Samsung’s Exynos-powered smartphones — including its latest Galaxy S III and Galaxy Note II devices — that can provide attackers with access to all physical memory. The flaw leaves the handsets open to malicious apps that can access a user’s personal data, completely wipe their data, or worse, brick their handset.
