How To Restart An iPhone or iPad The Right Way!
This is something to try whenever you're having problems with your device. Get to the main screen showing all your apps. Then press the home button on the front two times quickly. You'll see small previews of your currently running apps. Swipe up on each app preview until the only screen remaining is your home app screen. Then press and hold the On/Off button on the top or right side (depending on which iPhone or iPad you have) until you see slide to power off. Swipe the slide to power off confirmation slider to the right. Then wait about 30 seconds and press the On/Off button again until you see the Apple logo to turn the device back on.
