Take Screenshot with your Samsung Vibrant is real easy. If yours is the Samsung Vibrant, heres what you need to do. Its a secret feature actually.
1. Be sure you are running on Samsung Vibrant.
2. When you are in the specific screen which you desire to take Screenshot, Carefully Press the Back button in right bottom and hold it. While holding Back button now press Home button in the middle. You will hear a capture sound and in moment it will appear Screen captured. Save as image file
3. It’s that easy! You’ll see a message appear on the screen that says “Screenshot captured. Saved as image file”. You can then go to your Samsung Vibrant Gallery app to see the screenshots that you have captured in the ScreenCap folder. You can also find them by navigating to the /sdcard/ScreenCapture folder.
I say press ‘carefully’ because if you press the menu button a fraction too early, the screen will drop down to the menu. And if you press the side power button too early and not along with the menu button, the screen will lock. Its very hard getting used to.
If you recently updated your Samsung Samsung Vibrant to the latest version of Android 4 ICS (Ice Cream Sandwich) the methods above may no longer use. Then try this instead:
Press Volume Down button and the Power Button at the SAME time to take a screenshot on Samsung Vibrant. The screenshot will be added to the /sdcard/Pictures/Screenshots folder.
All of these require skilled operation, if the operation is unsuccessful, You must go to Google tosearch “Samsung Vibrant screenshots”
