Like many of you, I've also been having the same issue recur off and on with my replacement Instinct. It seems to get things back to normal if I take my fingernail and run it along and under the edge of the screen. Often I can get the screen to start working again. However, I think I will need to just take it back in for another replacement. Personally, I think the worst thing is that almost all the new phones coming out at touchscreen. I wonder if touchscreen phones made by other companies (other than Samsung) have similar issues. Needless to say, I will always pay for the insurance/replacement, because if I have to get a new phone each year due to this (or sooner) it's too expensive to not have the insurance.
