Samsung Galaxy S3 Will Test the "Big Screen" Theory

The Galaxy S3, which tracks the user's eye movements to keep the screen from dimming or turning off while in use, and features a giant 4.8-inch screen, is launching in 28 European and Middle East countries. The U.S. launch will probably come in July 2012.

The Galaxy S3 is deemed by some observers to be the single device best positioned to compete with the Apple iPhone, including the upcoming version of the Apple iPhone.

The smartphone, running on Google's (GOOG.O) Android operating system, boasts a 4.8-inch (12.2 cm) screen, one of the largest on smartphones ever, and much bigger than the 3.5-inch display on the iPhone 4S.


In the first quarter of 2012, Samsung sold 44.5 million smart phones, giving it 30.6 percent market share. Apple sold 35.1 million iPhones, taking 24.1 percent market share.
