Mine is on, my OCD sees that it is slightly off center by the tiniest bit. About 5 minutes after curing the glass for 10 minutes, I put it in a case (Caseology Skyfall) and the one corner (because it's slightly off center) lifted. I took it out of the case, pushed the corner down, and let it sit out over night, and now it's fine! I put it back in the case, and been using it in the case all day and it seems to be a perfect fit. just the tiniest bit of gap all the way around the screen protector and the case edges. If it drops and lands on a corner, it will definitely pop one of those corners off again. I really wish Supcase would bring the Style cases to the Note20/Ultra.
