26 steps

Swipe it from the left to right-hand side. Your iPhone will shut down in approximately 10 seconds.

Hard Plastic Picks

VAKUPLASTIC Suction Cup
Put your iPhone 6s on a soft, clean surface to avoid scratching the back.

Use a suction cup to lift the front panel, a hard plastic plectrum and a hot-air gun. If the screen is severely damaged, cover it entirely with adhesive tape before you continue.

The screen is slightly adhered to the frame. Use the hot-air gun to heat the outer edges of the display to about 60°C (140°F).

Place the suction cup over the home button or next to it. While lifting the screen with the suction cup, insert the hard plastic plectrum between the aluminum frame and the display frame. Try to press down the aluminum frame as well as to push up the display with the hard plastic plectrum. Usually this takes several attempts.

As soon as you can lift up the screen a few millimeters, slide carefully alongside the outer edges until the display is loosened on both sides.
If necessary, heat the outer edges of the display several times.
