Add double-tap to lock phone [duplicate]

As for me that's not a good idea, that's a risk to tap app icon or background one. As it works now by swiping from very top to down is good enough, one finger is enough. Anyway, if only in Settings, not by default.

for the comment, this is about lock-screen there is currently nothing you could tap accidentally and also I am not requesting to do that by default.

Swipe down from edge to lock the phone is a beautiful feature and consistent with the rest of Sailfish layout (swipe down to close). To make a separate gesture that only functions in lock-screen is redundant and may lead to confusion imho.

as I said, I tried (and not only me also others, close to anyone I showed the double-tap to unlock feature tried to lock it or have another action with another double-tap so it is more unintuitive to not have it!) to lock the phone with a double-tap and still find myself trying to do that, what harm does it do to have an option in the settings to activate such a feature?!

My two cents: people have been taught to get used to doing the same thing for unlocking and locking by key-based phones, whether it's android phones or iPhone (or even older/"dumbphones"). The same thing can be done with the power button on Jolla. "Intuitive" doesn't equal learned behaviors, but allow muscle memories. Dobble-tap to unlock (I call it the knock-knock feature) is like knocking on the door. You don't knock because you want the door to close on you. If I'm to dobble-tap for both actions, I can totally see myself doing the same with outside of lock screen without thinking because of muscle memory and getting unwanted responses from the phone. I already get annoyed why gestures don't work when I'm on other phones forgetting they're not Jolla. :)
