The South Korean electronics giant released the Galaxy S6 and curved S6 Edge at Mobile World Congress in Barcelona as it looks to turn round its fortunes after a year dominated by the iPhone 6 and 6 Plus in the premium end of the market.
Both devices have a 5.1 inch screen with a 16 megapixel rear camera and 5 megapixel front camera. But the screen on the S6 Edge curves over the sides of the smartphone.
"This phone is more powerful than every Galaxy device before. It is a new generation of design," Jean-Daniel Ayme, deputy president of Europe for Samsung, told CNBC in an interview.
"We are very confident that this device will be hugely successful," Ayme added when asked by CNBC how the S6 Edge would fare against the iPhone.
Both smartphones can be charged wirelessly, a feature the South Korean company teased last week in a blog post. Other features include a heart rate monitor and ability to view apps such as the time or stocks on the side screen of the S6 Edge.
