In front lies a 1.9-megapixel camera, which is far different from what most of the other smartphone manufacturers throw in (VGA quality cameras), since you can now even record HD videos using the front-facing camera.
The whole idea of a higher resolution count is to have the Galaxy S3 adapt to you, whereby this camera will be able to help the Galaxy S3 recognise how you use the handset, and to maintain the display's brightness level for the task at hand (reading an e-book, checking emails, playing games).
In what can be seen as a response to Siri on iOS, the Galaxy S3 will feature S Voice, which has been dubbed as an "advanced natural language user interface", in which it is capable of listening and responding to your words.
Apart from offering information search and basic device-user communication, S Voice will also let you control the Galaxy S3 through speech alone.
For example, you need not fumble for the "Snooze" button when the alarm rings, just say the word, and it will respond accordingly. It can also be used to play back your songs, control the volume, send emails and text messages as well as organise your calendar, among others.
