The Samsung Galaxy Note 4 is still quite a distance away from launch, but a new patent application by Samsung might have already given away part of the surprise. A new patent filing suggests the Korean manufacturer could introduce the ability to perform handwritten actions from the lock screen.

Samsung is known to be working with the YOUM flexible display panels since last year; it’s new Galaxy Round — which made it the world’s first manufacturer of a curved glass smartphone — is evidence of that. And a new report from a Korean analyst claims that Samsung might bring this technology to its mainstream devices like the Note series as soon as this year.

Remember that recent Samsung patent that detailed a new smartphone, believed to be a future Galaxy Note, with a wraparound display? Well designer Jermaine Smit has turned Samsung’s illustrations into a gorgeous Galaxy Note 4 concept that looks so good it almost guarantees the real thing will be a disappointment.
