I saw a thread about this. People kept posting links and app names. This thread will show you the key combination to take a snapshot of the screen using the stock screencapture service. Magical combination: hold search key, tap back key. If you have apps like drocap, et cetera, it will ask which app to use. If you have none, it will take a snapshot and save in ScreenCapture directory. Just putting this out there for all of the people who found com.sec.android.app.screencapture to be suspicious.
