Press both the volume down key + power key. Now let's see the new method screenshots. You will have to first check a box that is disabled by default. To enable this checkbox you must go to Settings / Motion menu and in this section we have to activate "Move palm to capture" box. Now that you have activated to capture a screen have to slide the palm of your hand from left to right or vice versa, so simple motion sensor. Catches the'll find as always in the gallery of images in a folder called "Screenhots". In case you have any doubt I leave a video so you can see how simple it is.
