Starting maybe two years ago, capacitive buttons are gradually replaced by on-screen buttons, and for good reasons, they are fully customisable, allow larger screen/body ratio, less flex cables running inside, saving a bit of battery... The last thing that keeps the capacitive buttons alive is that some phones still use 5" or smaller screen so the use of on-screen buttons is not prarical. What do you think about capacitive buttons? Personally I prefer them over on-screen buttons, love the backlight that grow in the dark, they don't mess with apps's interface. I'm kind of missing them.
