Taking screenshots on Samsung Galaxy Nexus with Jelly Bean Apparently on Ice Cream Sandwich you can press power + volume down to take a screenshot, but this doesn't work for me with Jelly Bean. Anyone know how to take a screenshot on a stock Galaxy Nexus with Android 4.1?
You need to press the Vol Down and Power buttons together, and hold them for a second or so.

Some users report that it works better if you press both buttons simultaneously, as opposed to one after the other in sequence.
