KNOCK FEATURE
Another feature Huawei was keen to point out during the launch event for the P8 was its Knuckle Sense Technology.
Basically what this means is the P8 can detect whether you’re tapping the screen with your fingertip or knuckle, and perform a different action depending on which you’re using.
Double tap the screen with your knuckle and the P8 snaps a screenshot, while drawing a circle will see a crop tool appear allowing you to select a part of the screen to cut out and save for later.
