If you want to learn how to take a screenshot on the HTC 8XT. Then your on the right page. It is actually quite easy to take a screenshot on the Sprint HTC 8XT or any windows phone 8. Here is a photo of me attempting to take screenshots with one hand only, and finally succeeding. All you have to do to take a screenshot is to press both the power and the Windows button at the same time. You will hear a beep and a camera sound to confirm that you have taken the picture. In the top status bar area, you will see “Saving screenshot” message.
