Sure, tapping, dragging or holding down an app icon on your smartphone's lockscreen may be handy, but it's apparently not good enough for Samsung.
According to a patent application spotted at the US Patent and Trademark Office, Samsung has filed a feature which "verifies a user and executes applications via handwriting recognition."
You can already unlock the Galaxy Note 2 and Galaxy Note 3 by scribbling your signature on the lockscreen, but with patent US 20140038557 A1 Samsung wants to use your handwriting to directly launch applications.

In accompanying images filed with the patent application, examples of how the feature may work are shown, with a S Pen stylus writing the phrase "Call mom" on the lockscreen, which in turn will jump you straight into the call.
There's no guarantee that this feature will make it to the Galaxy Note 4, or even subsequent Note smartphones and tablets, but it's certainly something we'll be keeping an eye on.
