With over 11 million units sold in its first month on the market, Samsung's (NASDAQOTH:SSNLF) Galaxy S5 is an unqualified hit.

And yet, no one should be surprised to read that. Despite stiff competition from Apple (NASDAQ:AAPL) and other Android handset makers, Samsung has emerged as the top dog, controlling more than 30% of the smartphone market in the first quarter.

Success has come with each new handset. From the Galaxy S selling 24 million units out the gate, to the S3 achieving 9 million pre-orders, to the S5's sparkling debut, Samsung is putting up the sorts of numbers you'd expect from a leader. A company capable of challenging Apple in its most important business.  

In the following slideshow, Motley Fool Senior Tech Specialist Tim Beyers provides a visual history of the Galaxy smartphone series and answers the question of whether now is the time to buy Samsung shares.

Leaked: Apple's next smart device (warning, it may shock you)
Samsung may have the edge right now, but Apple is fast at work on a breakthrough of its own.

In fact, ABI Research predicts 485 million of this type of device will be sold per year. But one small company makes Apple's gadget possible. And its stock price has nearly unlimited room to run for early in-the-know investors. To be one of them, and see Apple's newest smart gizmo, just click here!
