Samsung has unveiled its latest flagship smartphone - the Galaxy S3.
The handset has a 4.8 inch (12.2cm) screen, an increase on the 4.3 inch screen of its predecessor.
The device is perceived to be critical to how people view both Samsung's brand and the Android system it runs.
Analysts say the popularity of the previous Galaxy - the S2 - was a major factor in the firm overtaking Nokia to become the world's best-selling mobile phone maker
