Default Is my screen broken?

Today at random a certaim part of my touchscreen reports two touches. If i touch there the screen responds as if I'm touching there and about half an inch below. To have an idea open the play store and go to an app. Where it says install, if i click there it also clicks the app pics. I trsted it with developer options to show screen touches. Two dots appear. Is this a bug or a phone that needs replacement?
