Android 4.0 and newer include an easy-to-use, built-in screenshot feature. You can take a screenshot and send it off your smartphone or tablet in just a few seconds. This feature was introduced in Ice Cream Sandwich (Android 4.0).
In the Android 2.x series, you could generally only take screenshots of your Android phone or tablet by rooting it or connecting it to a computer and using Google’s Android SDK.
Taking a Screenshot
To take a screenshot on your device, press the Volume Down and Power keys at the same time.
The screen will flash, you’ll hear a sound, and you’ll see a framed image appear and fade into the notification bar. The “Saving screenshot” notification will appear.
You can view a portion of the screenshot from your notification drawer on Android 4.1 (Jelly Bean) and later. Pull down the drawer with your finger. If you don’t see the expanded notification, pinch the screenshot notification and expand it with your fingers.
To easily upload the screenshot, tap the Share button. For example, if you have the Google Drive app installed, you can tap Drive to upload the screenshot to your Google Drive. If you use Gmail, you can tap Gmail to send the screenshot as an attachment by email.
You can also tap a screenshot in the notification drawer to directly open it in the Gallery app. From here, you can preview it, crop it, share it to another app, or delete it.
Working With Multiple Screenshots
All screenshots you take appear in the Screenshot album located in the Gallery app.
From the Screenshot album, you can tap the menu button and use the Select item option to select multiple screenshots, Once you have, use the Share menu to easily share them with another application – to quickly upload multiple screenshots to your Google Drive or Dropbox, for example.
You can also connect your Android device to your computer and copy the screenshots over from your device’s file system. They’re located in the /sdcard/Pictures/Screenshotsfolder.
