Samsung unveils new flagship Galaxy S smartphone

Samsung has unveiled its flagship Galaxy S smartphone's latest models, more than a month ahead of its usual annual release schedule.

The standard S21's screen size is 6.2 inches, with the S21 Plus at 6.7 inches and S21 Ultra is 6.8 inches.

With the most advanced processing chip in any Galaxy device, the S21 is 5G compatible and designed for navigating on-screen work and play.

The top end of the range, the Ultra - features a stylus for on-screen work called the S Pen, but it has to be bought separately. It also sports a four-lens rear camera that allows different angles and zoom shots.

The series will be available starting January 29 through its website, carriers and retailers online, Samsung said.
