This hidden iOS feature solves one of the iPhone’s most annoying problems

I wish I'd known how to stop the iPhone lock button ending calls earlier.

You see, the way I hold my phone when on a call means that I regularly knock the lock button. By default, this ends the call you're on.

I appreciate why this feature is useful, allowing you to end the call without looking at the screen. The thing is, even though I've known the lock button ends calls for a long time, I never use it and always bring my phone down to look at the screen, whereupon I tap the red 'hang up' button.

This might have something to do with being on my phone all day — so bringing my device down to to view the screen is returning the iPhone to its default position. Whatever the reason, though, that's just what I do. So I've always found using the lock button to end calls pointless and annoying when accidentally pressed during a conversation.

I'm kind of surprised then, given how much I know and write about iPhones, that I didn't know about this feature sooner — although, to be fair, it is tucked away behind two sub-menus and is easy to miss.

You can actually disable the iPhone's lock button being used to hang up a phone call. It's little hacks like this which, in my opinion, make iPhones some of the best phones around.

If you're anything like me, you'll want to do this too, so read on to find out how to stop the iPhone lock button ending calls.
