When I visit some android forums, I just find some threads are talking about how to take a screenshot like ios on Android. As we know, the native android system do not has such function to take a screenshot. But we can use the third-party apps to finish it.
However, those third-party apps would only work on certain devices. Those devices need to obtain the administrator authority by rooting. But the Motorola mobile phones had been locked and can�t be rooted. Then there was also the SDK method for taking a screenshot, which wasn’t always the most convenient.
Well, after some unrelated sentences, let�s get out topic start. Actually, this step is so easy for Android 4.0 Ice Cream Sandwich because it allows users to quickly take and view a screenshot without any fancy tools or tricks or root.
As we know Galaxy Nexus is the first device with Android 4.0, so let us take this mobile phone as an example to get a screenshot. At first you need to press the volume down button and the power button, at the same time for a couple of seconds. And then you will see an animation showing you’re the screenshot. You can view the screenshot by tapping on the thumbnail in the notification tray, or by visiting your Gallery app.
