Sony Xperia Z has a built-in option for taking screenshot. To bring the option, just press the Power button. It’ll open the power options. You’ll see ‘Take Screenshot’ menu (the last option) in the power options. Just tap on it. Your screenshot will be saved in the Screenshot folder inside the Gallery. In addition, you can also capture screenshot on Sony Xperia Z/Xperia ZL using Android’s native screen capturing ability. Just press the power button and volume down key simultaneously for about 2 seconds. That’s all.
