Iphone 1 1 how to hang up?

In the first case, if you are operating a mobile phone, the caller ID has two options: reject and accept, which is well known. As shown in the figure, you can hang up the phone simply by clicking Reject.

In the second case, when the phone is locked, the phone interface only displays the option of sliding answering, and many people don't know how to refuse. Actually, it's very simple. Just press the power button.
