If you ever have a need to take a screenshot on the Samsung Stratosphere smartphone, the capability is built right into the phone.
1. Press both the Power and Home buttons briefly.
2. You should hear a “click” sound and the screen will say “Screen captured. Saved as image file“.
3. You can access your screenshot images by opening the Gallery app and selecting the ScreenCapture folder. If you need to pull them over to your computer, mount the Samsung Stratosphere and access the ScreenCapture folder located in the root directory of the SD card.
