Method 1: With the physical buttons

El LG G2 It does not have an ordinary keypad, as we have seen in different videos that circulate on the network, this terminal There is no button on the frame or on the front of the device. The only buttons it has are the volume and power buttons located on the back of it.

To capture the screen in which we are working at that moment we will only have to access Quick Memo and save the captured capture. This option, in addition to saving the screen that interests us, also gives us the option to mark annotations.

Another very fast way to access Quick Memo We have it through the Home button, if we hold down the Home button and scroll up, the option to open will appear Quick Memo or enter Google Now.
