Galaxy S8’s screen is so big there isn’t room for the Samsung logo

It is said to cover 83% of the smartphone's front face, forcing the fingerprint scanner and Samsung logo around the back

A picture claiming to show off the Samsung Galaxy S8 has been posted online, along with purported specifications and launch plans.

The handset will be available in 5.8-inch and 6.2-inch options and will be officially unveiled at an event on 29 March, according to VentureBeat tipster Evan Blass.

The picture appears to back up past reports describing the S8’s dual-edge curved “infinity display”, which is said to cover 83% of the handset’s front panel, leaving no room for a home button or even Samsung’s logo.

The company’s branding will instead sit on the rear side of the phone only, beneath the 12-megapixel camera sensor and fingerprint scanner.

The latest leak also claims that both models of the S8 will feature a 2,560 x 1,440 Quad HD Super AMOLED display, an 8-megapixel selfie camera, a USB Type-C port, a headphone jack and pressure-sensitive touch technology similar to 3D Touch on the iPhone.

They’ll also run Android Nougat and use the Snapdragon 835 processor – Qualcomm’s fastest, most energy-efficient mobile chip – paired with 4GB of RAM.

That claimed energy-efficiency boost could be crucial, as the 5.8-inch version of the phone is expected to be powered by a 3,000mAh battery, with the larger model featuring a 3,500mAh battery. Both sound fairly conservative, when you consider how demanding the enlarged, QHD display is likely to be.

The Galaxy S8 is reported to go on sale on 21 April, with the 5.8-inch version costing €799 (£680) and the 6.2-inch model priced at €899 (£770).
