Angstrom i7 As a display screen with touch operation, simple gesture operation directly determines whether the user experience is good or not. Ultra low power consumption MeMORY The capacitive touch screen can be controlled by sliding from left to right, up and down, and pressing for a long time. It is really simple and convenient, and does not pay for complicated control and learning. In fact, the sensitivity and accuracy of touch control are slightly delayed and still need to be improved. The problem is that when you slide up and down or left and right, you will directly return to the main control interface.
