After downloading the updates, which presumably fixes this issue (firmware: 1028.3562.1402.1001), I can conclude the following:
The update does actually address this issue, but I won't say it's completely resolved. There are still some instants where a swipe wouldn't work at all (won't do a tap now).
What I was referring to earlier, about this problem being related to hardware rather than software, I am still convinced that there is an issue, but I need some of people testing this as I only have my device around and it suffers from it.
What I want you to try is when standing in the sun (in a shaded area during the day), and the screen jumps to high brightness and screen readability mood, open up the dialer and try to press any of the numbers normally. Now notice if the screen colors are scrambled, like if you were pressing so hard on the screen, it usually appears in the middle of the screen when you aren't even pushing it that hard, just tapping.
I currently have this issue, and I am wondering if all devices have this. If they do, then I suspect that this is a manufacturing defect in all devices, and affects the touch screen performance as it's pushed hard against the body of the device.
