How do I hang up a call with iPhone 6 and iOS 9.0.1?

I know that this answer is years off, but I believe you have to tap the "contact photo" and the hang up option should appear. Not sure why they would hide the button to begin with.

You are assuming that most phones do this, they don't, yours does.

had problem for long time. apple is in denial

Finally a solution, thank you!

do not feel stupid. apple is at fault. my phone does whatever it wants

works when their initials are there, but not always the case

I have the exact same problem, VERY frustrating!

Tap the power button 2x. This disconnects the call on 5S and SE too.

I am facing the similar call handling problem. hope there is a real good solution to this or has apple ignored user friendly features with new versions!!

I am an iphone user since 2008 and this method worked fine so far. but tried this on 7 and at all different speeds of 2x. It has not helped.

THIS IS DRIVING ME CRAZY. PRESSING THE SLEEP/WAKE/POWER BUTTON DOES NOT WORK ON THE IPHONE 5. PLEASE APPLE FIX THIS. ADD THE END CALL BUTTON BACK.

Because that was up to the OP. They mark it and once it is marked, it cannot be changed.

I can’t hang up even on speakerphone.
