I used it for almost two years without once because of the AR screen but the oleophobic coating died in about half that time, so I finally caved and got a screen protector (a thin 0.18mm tempered glass). At first the sensor worked almost as well as it used to, but a month or so in and it's starting to get inconsistent for me and sometimes just locks me out. What's going on?
