Samsung Galaxy S3

The Samsung Galaxy S3 (sometimes labelled the SIII or i9300) is a smartphone designed, developed, and marketed by Samsung Electronics that runs the Android operating system. Compared to its predecessor, the Samsung Galaxy SII, it has additional software features, expanded hardware, and a redesigned exterior. Additionally, the SIII employs an intelligent personal assistant (S Voice), eye-tracking ability, increased storage, and a wireless charging option. Depending on country, the 4.8-inch (120 mm) smartphone comes with different processors and RAM capacity, and 4G LTE support. The device was launched with Android 4.0.4 "Ice Cream Sandwich", and can be updated to Android 4.3 "Jelly Bean". 

Samsung unveiled the Galaxy S3 on 3 May 2012, following an 18-month development phase. The device was initially released in 28 European and Middle Eastern countries on 29 May 2012, before being progressively released in other major markets in June 2012.

The Galaxy S III was well-received commercially and critically, with some technology commentators publicising it as the "iPhone killer". Accordingly, more than 20 million units of the S III were sold within the first 100 days of release. Samsung has since sold more than 50 million units.

Given the Galaxy S III’s staggering success, the glowing reviews it has received from trade publications should come as no surprise. In September 2012, TechRadar ranked it as the No. 1 handset in its constantly updated list of the 20 best mobile phones, while Stuff magazine likewise ranked it at No. 1 in its list of 10 best smartphones in May 2012. The handset also won the "European Mobile Phone of 2012–13" award from the European Imaging and Sound Association, as well as T3 magazine's "Phone of the Year" award for 2012. In November 2012, research firm Strategy Analytics announced that the Galaxy S III had overtaken the Apple iPhone 4S to become the world's best-selling smartphone model in late 2012.

The phone's successor, the Samsung Galaxy S4, was announced in March 2013 and was released the following month.
