Samsung has unveiled two new flagship smartphones, the Galaxy S7 and S7 Edge.
The smartphones will come with an "always on" display, which can be used to constantly show the time, while the camera in both devices has also been reworked to provide better photos in low light.
The all-metal design that was introduced on last year's S6 continues, with the Edge remaining the only phone with a curved screen on both sides of the device.
The Korean technology giant has also reintroduced waterproofing and expandable storage through a space next to the SIM for an SD card.
A 360-degree camera, called the Gear 360, was also introduced and will enable users to film and take pictures up to 360 degrees, and post the results on Facebook and YouTube, both of which support the technology.

The unveiling came amid a press conference in Barcelona, which Samsung delivered via virtual reality, placing a VR headset on every seat in the hall for those in attendance.
The curved screen that appears on the S7 Edge was first introduced on the S6 last year, and has proved popular with consumers and industry experts.
The screen on the new Edge also has an expanded side menu, meaning two rows of apps can now be shown, and third-party apps can now use the space to show images and news stories, Samsung said on Sunday.
Samsung added that battery life on the new devices has also improved, and that both fast charging and wireless charging have improved too.
