In March of 2010, Samsung officially unveiled the Samsung Galaxy S, the very first entry in the new “S” line. Previously, in 2009, the company had launched the Samsung Galaxy, its very first phone powered by Android.
The Galaxy S was, at the time, one of the most powerful phones on the market. Its graphical processing power outmatched any other Android phone. It even trounced the iPhone 3G, which was the most recent Apple phone available at the time. This raw power coupled with an attractive design and slim form-factor pushed the Galaxy S to over 25 million units sold.
