One of the features I’ve long waited for on Android devices is the ability to easily and quickly take screenshots. There are ways of enabling this with some apps but those generally require you to have root access.
On my Nexus 4, that was one of the first features I looked for and it still didn’t exist. Or does it….
While I was putting my phone into my RAM mount holder, my fingers hit the power button and the volume down button and PLINK, it took a screenshot! It even saved it nicely into a “screenshot” folder in the gallery.
I’m not sure if this is only on 4.2 or whether that feature also exists on 4.1, or whether it’s specific to the Nexus phones.
Give it a try and let me know how available this is across recent Android OS versions and devices.
