How to hang a call when screen is off
Hi
New to iPhones, I got an 6S, but I don't know how to hang a call when screen is off.
I have to identify, tap on the green header, and then I can press on the red button. But most of the time, the correspondent hung before.
Isn't it any fast solution?
(pressing the on/off button or double tap doesn't work)
Thanks
