Many weeks ago we made an article explaining what to do if the iPhone was hanging.Until today, almost 3,4 weeks later, the “trick” has worked smoothly with any model of iPhone that has left, but with the launch of the new iPhone 7, the thing has changed slightly due to its new home button.
That is why if you plan to buy an iPhone 7, either the normal model or Plus, you will be interested in this mini guide in case any application is left hanging, there is no way to turn it off and you have to restart it.
All you have to do is press and hold the Power button + Volume down button, and wait for the phone to turn off and Apple’s apple appears. At that time you can release the two buttons and wait for the full restart.
When it starts up completely you can continue using the iPhone 7 normally.
