Samsung Rolls Out Galaxy S3

Samsung launched the Galaxy S3 smartphone in 28 European and Middle Eastern countries on Tuesday—the company’s latest effort to topple the iPhone. The South Korea–based company managed to overtake Apple in sales in the first quarter of 2012, but Apple is expected to release a new iPhone in the third quarter of this year. The Galaxy S3, which runs on the Android operating system, can track users’ eye movements to keep the screen from dimming while in use. Samsung said it will release the system via 296 carriers in 145 countries by July.
