(Ladies? and) Gentlemen, please, grab a hanky and dab away my tears...
String quartet - play us a sad one...
Galaxy S2 - not a blemish
Galaxy S4 - not a blemish
Galaxy S6 - one deep scratch after approximately 18 months' use - fair innings - was bothered but not enough to act
Galaxy S9+ - a one-inch and tangibly deep scratch after only under three days unboxed

Prime suspect is the small metal clip on my work ID lanyard. I've been careful to keep it away from my keys, etc.
Before all the "told-you-so mumsnets"

chime in about cases and screen protectors, I have a case on order but the one I had my eye on - Spigen Reventon - is not yet available. The ticking time bomb has, if not entirely gone BOOM, has at least sparked. I am sad but hey, worse things have happened, and will happen yet!
Got some cerium oxide paste on way from the rainforest - they don't necessarily recommend that it's used on phone screens but I'm not sure what else to try. Maybe some of the wax I use on my motorcycle's petrol tank. I suspect it's too deep to rectify though, I can easily feel it with my fingernail and it is visible from all angles.
Anybody got any fabulous ideas? Tried and tested first-hand - not internet myth please

. I'm hopeful that if I can fill it with something and then lay a protector over top it may stay filled and hidden...
