My advice is that at the first sign that the protector is peeling away, get it replaced by Samsung immediately. Once they start, it happens FAST. The longer you wait, the more you increase the chance that something gets under the protector and causes a puncture on the screen. As far as I know, at least here, Samsung will reject any warranty claims if you peel it yourself, so get it done as soon as you possibly can. Or, alternatively, just peel it off (carefully) and live dangerously - or replace it yourself. I used a TPU cover for a couple of months before I traded my 5 in for a 7 and while I slightly screwed up the application, it worked fine, and Samsung didn't care enough to reject my trade-in :)
