How do I take a screenshot?
Android devices
You should be able to take screenshots on most Android devices by holding down the ‘Power’ and ‘Volume down’ buttons. Some devices also have a screenshot button in the pull-down menu.
Apple devices
Press the side button and the volume up button at the same time. Quickly release both buttons. After you take a screenshot, a thumbnail temporarily appears in the lower-left corner of your screen. Tap the thumbnail to open it or swipe left to dismiss it.
