You can also use
Screenshot Sharer App to capture and share screenshot simply by long pressing your home button. We recommend it.
Since LG K40S is an Android device, you may click a screenshot easily using the following method
* General method for Android Devices
- Press and hold Power button and Volume Down button (on some devices with physical keys: Homescreen button and Power button) for about 2-4 seconds, in order to take screenshot.
- Once you hear a camera sound or notice that the screenshot has been captured, release the buttons.
- Your screenshot then will be stored in the Gallery app, in the Screenshots folder.
* Alternate method (working on many devices) *
- Press and hold the Power Button for 2 to 4 seconds
- Choose the option to take screenshot if it appears
* Did not work for you? Try this method: (For HTC and some other makes) *
- Press and hold the Power Button for 1 second
- Without releasing the Power Button, press and hold the volume down button, both for 2 seconds
- Hopefully your screenshot will be captured. :)
In most cases, you should see a notification that your screenshot has been captured. You may choose to share it, right from there as well.
Screenshots are saved in Screenshots folder and may appear in Gallery of your phone.
