Hi CMF Hacker, the pre-applied protector is just a fairly common plastic film protector, not great quality and thus simply is prone to scratches. Your’s would have scratched sooner or later anyways.
There are a number of tempered glass options already available on Amazon, however I haven’t ordered any of these, as I am currently hoping Spigen will release one within the next month.
In secret I still have a faint spark of hope Nothing would actually release their own tempered glass protector, as the one they did for NP2 has been pretty much perfect in every single aspect.
