I'm not sure if you guys know this or not, but after seeking numerous reviews before buying my phone, I, personally, had no idea this phone could do it without being rooted. After I actually investigating it with my phone, I found a way to take a screenshot without rooting, and without an application to help either. All you have to do is, similar to apple products, press the home button and power/lock button at the same time. Again, similar to apple products, your screen flashes white and there's a tone played. Discovered this after finding a 'Captured Images' folder in my gallery, when I had no clue how I'd managed it. I mashed buttons in an attempt to recreate it, some days later I found it, and figured I'd tell you guys, just incase you didn't know.
