It's definitely not sloppy thumb. It is extremely sensitive screen. My friends also does it anywhere there is text.
I've tried everything. being super careful. It's very annoying because then you have to hit "back" button to stop copy/paste so you can continue to scroll down. Unfortunately since it's always doing it, I have to hit "back button several times before I get to where I want to go.
Yeah i also have that problem, and it also has only been doing it since 148 and 151, and it is extremely annoying. Im thinking its some kind of software glitch.
