How to take a screenshot with an Android device? Is there a way to take a screenshot of an Android device and save it as an image file?
If you have Android 4.0 or higher:
You can press the Power button + the Volume Down button at the same time to take a screenshot. It will be saved to your gallery.
Note: You need to keep the buttons pressed for around a second for this to work. This is to avoid the screenshot when this combination is accidentally pressed.
UPDATE 8.3.2021: If you have Android 10, you must press the Power button + Volume Down buttons ONLY BRIEFLY (&lt; 0.5 seconds). If you press them longer, the Power menu will just open and the screenshot will not be captured.
If you have an Android lower than 4.0:
If you're rooted: you can install an app called drocap2. This will let you shake your phone, wait on a timer, or click on a notification in your notification bar to take a screenshot and it'll save it to your phone.
If you're not rooted: you can not run a screenshot app on your phone, period. You'll have to install the Android SDK on your computer, connect you phone via USB, and run a program called DDMS. This program is mainly used for developer debugging, but it has a screenshot utility under one of its menus.  For a tutorial, see this page.
Also, some constructor like Samsung have implemented this function on their phones (the buttons combination change from phone to phone, so search for yours).
