How do I take screenshots on a Samsung Galaxy A3? I've been trying to take screenshots on my Samsung Galaxy A3 by using both the "home + lock" key combination and the "volume down + lock" key combination, and neither have worked. I don't want to install a Screenshot app on my device.

Does anyone know how to take screenshots on it without downloading any type of Screen Capture, Screen Grab, or Screenshot app?
Try holding Power + Home together a few moments. it works on all Samsung phones.

Also there's an alternative solution which works only on Samsung and Android 4.0+ phones (has to be activated in Settings > My device [tab] > Motions and gestures > Palm motion > Capture screen). It works by Swiping screen with the side of your hand.
