Using the power button/side key to end calls is a useful feature, but at times when I'm on a call using bluetooth headphones and just want to turn off the screen, there's no way to use the side key to do that as even accidentally pressing it just abruptly cuts the call. Which is annoying I hope they add another functionality to this by also letting the user to turn the screen off if the screen is on using side key then cut the call if we press it again.
