Samsung's already promised a "new form factor" for the Galaxy Note 4, so we wouldn't be too surprised if this new image of a mystery device is a hint at what it might look like.

The picture comes from a new Samsung patent unearthed by Galaxy Club and shows a device with a flexible screen that curves around the sides of the device.

It also shows that certain action keys, such as camera, email and settings, will be located on the wraparound side for more convenient access.

Bent on innovation

Galaxy Note 4Earlier this year it was reported by Korean Media that Samsung will launch a Galaxy variant with a "bent" display, and this could be exactly what it meant.

TechRadar recently went behind closed doors to see some of Samsung's Youm flexible display device prototypes, one of which was the three-sided phone Samsung originally showed off at CES 2013. As it turns out, the Korean company is still very keen on the design.

Given the similarity between the Youm and the new patent picture, we wouldn't be surprised if the Note 4 ended up looking quite similar.
