So, I accidentally took a screenshot today. I was just holding my phone in my right hand, having finished doing something or another & I heard a shutter sound (which puzzled me because I have the sound turned off in the camera).
Anyhoo, I went to the gallery and lo and behold there was a pic of my desktop in .png (everything else is .jpg).
Meandering about the web, I've seen that at some point we've gained native screenshot ability AND I've found a bunch of people who have done this accidentally & are looking for answers and a couple of people who have said, use the home & power button together. That just doesn't work for me. Can someone be a little more specific about what to do to achieve this.
