(Vivo XL) Screen shots while pushing the power button

[Exnavyphotog]

I am getting a screen shot taken every time I push the power button. I can't turn off the phone or put the screen to sleep without taking a screen shot. I've looked at at the camera settings and can't find how to shut off the screen shots. To turn off the phone I have to pull the battery and reinstall it. Any ideas how to shut of the screen shots?

Are you having problems adjusting your volume as well? It's possible the Vol Down button is stuck in a pressed state, so pressing the Power button would make the phone think you want to take a screenshot.
