Samsung receives a patent for the use of gestures to replace physical buttons on the Galaxy Z Fold
This render of the Galaxy Z Fold 3 is based on Sammy’s new patent
As an example, with the device folded up, a tap on the side could power up the phone while a swipe might allow users to control the volume. A squeeze gesture could also be used to replace physical buttons. As LetsGo Digital notes, foldable phones will be getting thinner in the future making it imperative for manufacturers to be able to use virtual controls. It also says to expect the Galaxy Z Fold 3 to be released in August sporting the next version of Ultra Thin Glass (UTG 2.0), which could allow the S Pen to work with the device.
