The I9000 Galaxy S was Samsung’s first ‘Galaxy S’ device – a franchise that would continue for many years as the company’s annual flagship smartphone. When it was announced it used the Android OS version 2.1 and featured very similar hardware specifications to the Bada-powered S8500 Wave
which had been announced a month earlier.
Like the Wave, the Galaxy S used a Samsung S5PC110 1 GHz processor and a Super AMOLED capacitive touch screen, but the Galaxy S boasted a four-inch screen compared with the Wave's 3.3 inches. It was the thinnest smartphone available at the time at just 9.9mm.
The Galaxy S immediately became Samsung's most successful Android device to date and by 2013, over 25 million units had been sold.
In contrast to its previous Android devices, Samsung had added a greater level of customization to the Galaxy S, which addressed many of the shortcomings of earlier products. It had also partnered with Swype to offer a far superior keyboard to the native means of data input on other touch-screen Android devices.
The Galaxy S added a number of bespoke features to Android. The Social Hub application aggregated a range of social networking services such as Facebook and Twitter in a widget on the home screen. Layar's Reality Browser was installed on the device and Samsung also added the Daily Briefing app providing stock data, news, weather and calendar information.
At the launch, Samsung outlined it's vision of convergence across multiple products and promoted the integration of DLNA
connectivity to the device which made it easier to seamlessly link to smart TVs and other connected products.
During its lifetime there were over 25 different variants of the Galaxy S smartphone offering different 2G, 3G and even 4G bands depending on the geographic region and carrier. This can be read in more detail on the phone's Wikipedia Page
