Just accidentally took a screenshot lol. hold power and press the home key.
Lots of pages say that you can take a screen shot on a Stratophere (I) by pressing the Home and Power keys together:
Samsung Stratosphere: How to Take a Screenshot
That works on my Stratosphere I.
However I had a Stratosphere II for about a week and the home-and-power key combination did not work for taking a screen shot.
I'm sure there must be a number of peope who know about this, but i accidentally bumped into this today and thought i would let others know.
In order to take Screenshots the easy way:
On the HTC Incredible Hold the Power Button, and before the power menu pops up, press the Home Key.. a screenshot is taken and is saved in a folder calld screenshots.
