For a while now most android phones could only capture what was on-screen using different tools, or applications and many required root access first. Apps like drocap, shootme, or Screenshot ER. Lately the outcry for this to be a stock feature has been answered by a few OEM's. First the LG Optimus and G2x got it, read about that here. Then we recently discovered it was also on the Droid Charge as well. We now can tell you the Samsung Galaxy S II also has a stock built-in screen capture feature.
For those of you starving for a way to take a screenshot on your Android device, have no fear! Your call has been heard by multiple manufacturers and it's being implemented all over the place! Today's example is the DROID Charge, a phone that we've got on hand and have just reviewed fully a few days ago. Have a look at that, then marvel at the ease with which you're going to be shooting your screen over and over and over again!
For those that use these kind of apps or have been around lately to notice that we didn't have one. The Motorola Xoom and any Android 3.0 Honeycomb device in general could not take screenshots with an app. There is drocap2, ShootMe and many other screen capture apps for our Android phones and apparently none of them worked on Android 3.0 but now a developer from the XDA forums named ftgg99 has fixed this issue for us. He has developed an app called Screenshot ER.
