Huh? Ok, maybe that’s your experience. That’s too bad if it is. My experience … this is not the way any of the three Windows touch screen devices work that I own and use regularly, including a Surface 3 LTE, Surface Pro 4, and a Dell Latitude 5179. I place my finger on a word on the screen and it does NOT select some other word. It selects the word I placed my finger on. To be fair, selecting one or two character words or digits may require slightly more precision on smaller screens, but I haven’t ever - up to this point in several years of using these three Windows touch screen devices - experienced this as this is just Windows being Windows type of thing. (I’ve never used a Windows phone though.)
The first thing I would try is to recalibrate the touch screen input.
