The Sony Xperia Z, believed to be Sony’s next-generation flagship smartphone, leaked a number of times last week, leading us to believe it would get its grand unveiling at CES in Las Vegas this week. In case you were at all skeptical, here’s a picture of the handset on the CES show floor ahead of Sony’s official announcement later today.

We got a glimpse of NVIDIA’s new Tegra 4 back in December, when a leaked slide detailing its specifications began circulating the Internet. But the company has now made the impressive chip official at CES 2013 in Las Vegas. Designed for mobile devices like smartphones and tablets, the Tegra 4 boasts a super speedy quad-core Cortex-A15 processor and 72-core graphics, making it the “world’s fastest mobile processor.”

The real deal?

A leaked photograph claimed to be of Samsung’s official Galaxy S IV press shot has been leaked online, along with specifications for the device. It reportedly came from an insider at Samsung, who claims this is the successor to the hugely successful Galaxy S III. It’s expected to offer a larger 4.99-inch 1080p display, plus a 2GHz quad-core processor. But is the image genuine?

It’s taken some time, but Android 4.1 Jelly Bean is finally beginning to claim a notable share of devices. Almost six months after its release, the software has been installed on 10.2% of smartphones and tablets, while Gingerbread’s share slowly diminishes. The vast majority of users are still running Gingerbread, Android 2.3, but the software share has dropped below the 50% mark for the first time in over a year.

Samsung has begun rolling out a software patch to address a major security flaw with its Exynos processor that leaves a handful of Android handsets vulnerable to attack. The update is first reaching Galaxy S III owners in the United Kingdom, but we would expect Samsung to be working hard to make this one available worldwide as quickly as possible.
