1. Hold down the "Power" and "Volume Down" buttons at the same time. If your device has a "Home" button (for example Samsung Galaxy Series) then you will need to hold down "Home" and "Power" buttons at the same time.
2. Let go of the buttons. You should hear a click and the screen should briefly flash.
3. Find your screenshot in your Gallery. The screenshot will be saved in Gallery > Screenshots
4. Use the screenshot. Once you have taken your screenshots, they are now ready to be used as needed. You can attach them to an email into support.
