According to a new recent patent application with USPTO, Samsung might be working on a new feature related to device unlocking. The patent application suggests that the company is working on a feature, similar to LG’s Knock Code, that will allow users to unlock their device just by touching on the display and dragging around to draw a figure with at least one intersection.
The description says that this feature will work even when your device’s display is off which means that users will no longer need to push the power key in order to turn on the display to use the feature. The shape, size or position of the drawing is not important given that there is at least one intersection point. In addition, users can assign a function two two, three or more intersection points. For example, you can assign WhatsApp to two intersection points so that when you draw a figure and there’s two intersection points, the application will be launched.
