Same here, had it on my XS (never had the screen replaced) for just over a month now. It began with the phone having a crazy seizure for about 10 mins, followed by a day of intense ghost touches and completely having a mind of its own, to then settling on the state its in now - the central, vertical portion of the screen at about a width of 1.5cm is completely unresponsive. I'm not going to lie, this has really, really put me off Apple. Not even so much as an acknowledgement of the issue, despite what I'd say is a substantial number of people who are making it known they have the issue too. I'm currently travelling Latin America and now in Mexico - not the kind of place you'd want a non functional phone.........
