There are several ways of taking screenshots on Android devices.
We are going to show you 2 ways. Both are focused on this device.
Android 4.0 or later
If you have an Android 4.0 or later, just press and hold the volume down and the power buttons at the same time. The screenshot will be automatically saved.
Manufacturer Shortcuts
There are also special shortcuts for the pre-Android 4.0 devices.
For example, on some Samsung devices you can take screenshots by pressing the home and power buttons at the same time. On the Galaxy S, just press the back and power buttons.
Some HTC devices are also able to take them by pressing home and power buttons, like Samsung devices.
But there are other ways to take the screenshots like:
- Downloading an app from Google Play to do it. Most of them require a rooted Android.
- Installing the Android SDK.
