Just days after insiders promised that a Galaxy S6 Plus was on the way, the device has leaked out ahead of its official unveiling. As expected, it’s a super-sized version of the Galaxy S6 edge, with a premium design and a display that curves on both sides.

The first photo of the S6 Plus was published by YouTuber Marques Brownlee (MKBHD), who confirms — based on the information provided to him — it will be a larger version of the S6 edge with similar specifications.

It’s hard to tell exactly how much bigger the handset is in the photo, but it comfortable fits five icons horizontally across its home screen. The original Galaxy S6 and S6 edge display just four by default, and you have to use a custom launcher and make them smaller to fit another one in.

Another thing that’s interesting about this shot is the icons themselves. They’re different to those Samsung is using in its latest version of TouchWiz — and more rounded — which suggests a future firmware update will bring some more design and UI improvements to existing S6 devices.

According to an earlier report from SamMobile, the S6 Plus will have a display measuring between 5.4 and 5.5 inches in size, and will be powered by a hexa-core Snapdragon 808 processor — a slight downgrade from the octa-core Exynos 7420 in the regular S6 and S6 edge.

We still don’t know when the device will be announced, but based on this image, it certainly looks like the handset is ready for its public debut.
