Also @Jason, I believe the default setting whenever you hard reset/reinstall the OS (and receive it from retail) that it is on "normal" -if I'm not mistaken.
It would be impossible (but interesting) to measure who is getting the actual phantom bug vs just having the high sensitivity setting on. I don't want to degrade anyone here, but there "are" some users who do not realize the difference between the touch settings. -however, I'd like to believe that if a user has had the phantom tap bug bad as me on both my 1520's, they would realize this...but whatever.
From the various tests I've done, it does seem like the problem exists even after a hard reset and OS flash...without even changing the touch settings. -even with the touch app uninstalled after a hard reset.
Some of you may think that I'm overreacting, but this bug seems to be worse on my ATT 1520 than my international 1520 at times. I could be scrolling the home screen and still get this issue. -opening twitter has never been so easy now /s.
