How do you take a screenshot on iPhone?

Added (1). Thanks for all the answers guys! Appreciate it, think it would be unfair to choose one as a best answer sorry!

Hold down the home button and lock screen

Click the home button and the off button at the same time (don't hold them)

Press both the home button then the button on top (Where you turn off the iPhone)

Press home button and power button at the same time( only two buttons on phone)

Hold down the home button and quickly press the on/off button. Your photo will be stored in photos.

Hold the button on the right corner( the one that turns it on and off ) and the circle down the bottom at the same time
Hope this helped.

Hold the top right button on the phone and te circle button in the middle bottom of the phone at the same time and the screen will flash quickly. Then you'll know it took the picture. Just make sure you click them both at the same time or it won't work.

Hold the home button at the bottom, the circle with the square inside at the same time hold the on/off button.

Ok first of all take your cover off the phone if you have one (i find for me it helps) now you can access your off button. Ok second press the home button and off button at the same time (off button on top of your phone and home button is the main button in the middle at the bottom at your phone) you should hear a click or a sound. Your screen goes white for a sec then you have your screenshot taken! Check your photos to see it!

To capture a screen shot:

Hold down the lock button and the home button at the same time for about one second and your screen will flash white. This will signify that the screenshot has been taken and you can find it in the camera roll.

You have to press the lock button and the home button at the same time, and you can then find the screenshot in your pictures

Hold down the home button the click the lock screen.
