OK so I read this forum and others for help with this problem and found no solution that helped me. I then messed around with it for a while. It seems to me you need to use the same method as before but press volume button closer to the middle, but still slightly to volume down side, while pressing power off button. As people say, it might take slightly longer to capture but only by a split second. Very confusing and frustrating but basically practice until you get the knack for it.... Hope this helps!! Happy screenshotting!!
