Taking a screenshot on the ASUS ZenFone 2 is easy, once you know a couple tricks.
There are three ways to take a screenshot on the ASUS ZenFone 2. One of them is the standard Android method of pressing power and volume down, like every other Android phone running Jellybean or higher. We all know that drill.
But when you put buttons on the back of the phone (and they are awesome when they are back there) doing it that way sucks. LG knows this, and so does ASUS. When you give us the glorious back-mounted buttons, you’ve gotta give us a better way to capture our screen.
