The first thing you need to know about taking a screenshot on Android is that it's not as straightforward as it seems. The Android OS has come a long way in a relatively short time, so before you learn how to take a screenshot or not you should check which version of Android your smartphone is running. If you have a relatively new smartphone (post 2011), like a Samsung Galaxy S3/S4, HTC One, Sony Xperia Z or Nexus 4, then you should be running at least Android HoneyComb, Ice Cream Sandwich or Jelly Bean, therefor taking a screenshot is a doddle. See all Android How-To tutorials.
However, if your smartphone is running Android 2.3 and below then things become a bit more tricky, but we'll come to that later on. See also: How to run Android apps on your PC or laptop

If you're running Android 2.3 and below then you're going to need to download an app to take a screenshot. This is where things get a little confusing as the effectiveness of the screenshot apps on offer vary from smartphone to smartphone.
If you're willing to pay for an app to enable you to take screenshots on your Android smartphone – and you don't want to go through the hassle of rooting your android then you should try the app No Root Screenshot It (£2.99). Bear in mind that “This application will instruct you to download and install a free desktop application on your Windows or Mac. Once installed, you must run the desktop application with your phone attached to your computer. This will enable screenshots on your phone”.
If you're unwilling to pay for a screenshot app, the only advice we can offer is to search the Google Play store and trial a number of apps based on their star rating and find an app that works well with your device.
