So here's the deal the power button works fine. The volume - key works fine also but when I try to take a screen shot it just won't. Either my volume just goes down or my screen turns off. I'm running stock 4.4.2. Thanks for the help!!!
Whoever said to press in a different place is confused... there are three buttons on the Nexus 4, Power, Volume Up and Volume Down... that is it. It doesn't matter if you press the ends or middle of the buttons, there are only 3 buttons. in some situations and some cases (meaning phone cases) the buttons may be off slightly or pressing the center may depress both volume buttons at the same time.OK so I read this forum and others for help with this problem and found no solution that helped me. I then messed around with it for a while. It seems to me you need to use the same method as before but press volume button closer to the middle, but still slightly to volume down side, while pressing power off button. As people say, it might take slightly longer to capture but only by a split second. Very confusing and frustrating but basically practice until you get the knack for it.... Hope this helps!! Happy screenshotting!!
I have the same issue from time to time as well. I also noticed when i can't use the snapshot function, holding the power button doesn't give me the "turn off" function as well.
Restarting the phone takes all the problems away... until it happens again.
