hi guys, not sure if you know this already but I found a way to take a screen shot without installing any app or rooting. on the galaxy s, simply press the home and back key simultaneously. I find it easier to do if I lightly touch both buttons first before clicking the home key. the screen shot will be saved in the gallery automatically. who says you need an app for that? not sure about other phones but on the galaxy tab, you need to press home, back and power button. please post here if it works for you in other phones or if there are other key combinations for them. cheers and enjoy!
