Hi Ana. I just checked the manual and found no information if it's possible to take a screenshot on the Coolpad Quattro by itself. I would suggest you just download apps from Google Play. Most screenshot apps require phone to be rooted first, but I found one that doesn't require phone to be rooted. It's No Root Screenshot It. I personally use this app. You can take a screenshot by shaking your phone, using the screenshot widget or delayed screenshot timer. Hope you'll like it too :)
I kno you can do a screenshot I jus havent figured it out but my 3yr old daughter has taken about 15 pictures of her playing on the phone i thought it had been jus the game till one day i gave her my cell too look at pictures and she took a picture of the pictures... i wanna kno how to do it.
If you want to take a picture from your messages, you hold your finger down on the picture and press add to gallery. If you want to screenshot, there is a blue lightning button at the bottom left of your screen when your in a message. You press it and a list of options come up, hold your finger on the screen and scroll down until you find screenshot
