It seems you can’t go anywhere these days without seeing an advert for the iPhone. They’re on billboards in the street, they’re there when you switch on the TV, and you’ll also find them in newspapers and magazines. But believe it or not, there’s one company that spends more — a lot more! — on advertising its smartphones than Apple does.

That company is Samsung. In 2012, Samsung outspent Apple by more than three to one in smartphone advertising, with a number of large campaigns on TV, in print, and on the Internet. In total, the Korean company spent $401 million advertising its phones.

Samsung’s official Twitter account has tweeted a teaser image for the much-anticipated Galaxy S IV ahead of the handset’s grand unveiling on Thursday, March 14. The image doesn’t give much away, but it does provide us with some idea of what the device will look like. And to be honest, we’re not all that impressed.

Samsung smartphones outsold those from rivals Apple, Nokia, and Lenovo in China throughout 2012, allowing the Korean company to claim the biggest share of the Chinese smartphone market, according to the latest report from Strategy Analytics.

Nokia had claimed the top spot in 2011, but the Finnish firm has struggled to compete with Samsung’s Galaxy devices this time around, and couldn’t even make its way into the top five.

On Thursday, March 14, Samsung will unveil the much-anticipated Galaxy S IV at an event in New York City’s Times Square. The Korean company has been very secretive about its next-generation Android flagship — as it was with the Galaxy S III last year — but pictures of the new device may have been leaked ahead of its official debut.

The image you see above was posted to Chinese forum 52 Samsung, and it’s just one of many of that purportedly show the Galaxy S IV. The handset looks a lot like a Galaxy Note II — albeit a slightly smaller version — but according to a benchmark test, its internals are very different.

While Samsung may be keeping the Galaxy S IV a closely-guarded secret until its grand unveiling on March 14, that hasn’t stopped a number of screenshots that were supposedly taken on the device itself from being leaked. One of the images reveals the handset’s specifications, which include a 1080p display, and a 13-megapixel camera.

There’s no sign of Samsung’s eight-core Exynos 5 Octa processor, however.
