Samsung CEO JK Shin expects the Samsung Galaxy S4 to surpass 10 million sales next week, less than a month after its debut. The milestone will make the new device the fastest-selling Samsung smartphone to date, a title that’s currently held by its predecessor, the Galaxy S III.

You’ve probably already heard about the awesome things announced at Google I/O yesterday, but if you didn’t get a chance to watch it yourself — or you just tuned out because it went on too long — then you can now watch the whole thing online.

We suggest skipping to the best bits, though, because it’s almost four hours long.

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.”
