The straight forward procedure to capture screen shots of your LG Magna phone screen is a two key process and there are two combinations to do this.
You may also search for the screen shot app in the play store which may also help do this. If the steps below do not work, then get the screen shot app from play store and then try performing the steps.
The app detects the phone’s model, enables required service for capturing screens and lists the steps as well.

a) Volume Down + the Power key
b) Home Button and the Power Key
You will see that the screen would flash when the right combination is sequenced followed by a camera click or a shutter sound, if the phone is not silent which confirms that the screen has been captured.
A pop-up notification may also appear notifying you that the screen has been captured.
The screen shots will be saved in the Gallery.
