Although, the iPhone 6 and iPhone 6 Plus have moved the sleep/wake button to a new location, however this screenshot function is still feasible and easy to use as ever.

1. Display anything you want to snap on your iPhone 6 screen.
2. Simply press and hold the “Home” button and then press the “Sleep/Wake” button. Once it’s done, you will hear a camera shutter which signifies that a screenshot is successfully taken.
3. Once a screenshot is captured, it will be automatically saved to your iPhone 6 Camera Roll. Thus you can head to your Camera roll and check the screenshot you have just taken. And then you can set it as wallpaper, share it via text messages, social networks like Facebook/Twitter, or edit it with the default photo editing app.

Tips: the sleep/wake button on iPhone 6 has been moved from the top of the iPhone to the right side.
