Hi Lisa here, and I'm going to show you how to turn off your iPhone. Now a lot of the time, people think that pressing this button one time is turning off the phone. Actually the phone is still on, so to turn it off what you're going to want to do, is not just press it once, but press and hold it. After a few seconds, you'll see this screen pop down, where it says, slide to turn off, you slide to turn off, and then it will actually turn off the phone. Now if you're using assistive touch, because this button doesn't work anymore, you can still turn your phone off. What you'll do, is you'll tap on your assistive touch button, tap on device, and then tap and hold on lock screen. Just like you were holding the button down, it will give you the option to slide to turn off again, and that's how you turn off your iPhone.
