Following its mammoth I/O keynote yesterday, which saw a number of services updated and new ones introduced, Google has added support for a number of additional devices — including the latest flagships from Samsung and HTC — to its Google Wallet app for Android.

As successor to the hugely successful Galaxy S III, the Galaxy S4 always had big boots to fill — but it appears to be doing that with ease. In just four days last month, Samsung shipped a staggering 4 million Galaxy S4 handsets. It’s now on track to ship 10 million by the end of May.

Apple has confirmed it will seek to add Samsung’s new Galaxy S4 to its ongoing patent-infringement lawsuit against the Korean electronics giant.

In a statement filed in the U.S. District Court in California on Monday, Apple said it has analyzed the Galaxy S4 and “concluded that it is an infringing device and accordingly intends to move for leave to add the Galaxy S4 as an infringing product.”

Nearly three in every four smartphones sold during the first quarter of 2013 were running Android, according to the latest statistics from the analysts at Gartner. Google’s operating system grabbed a whopping 74% of the market share during the three-month period, while Apple’s iOS came in second with 18.2%.

Companies choosing to build Windows Phone, BlackBerry, and Symbian powered devices might want to look away now.

Nokia has this morning announced its new Lumia 925, a Windows Phone smartphone with an aluminum frame that hopes to step up Nokia’s fight against Apple and Samsung. But does the Lumia 925 really have what it takes to compete with the iPhone 5, the Galaxy S4, the HTC One, and other high-end smartphones?

We’ve put together a spec-by-spec comparison to help you decide whether Nokia’s new flagship is worth the switch to Windows Phone.
