Screen scratched topic

Anyone notice their screen getting scratched up from just normal use? I've never dropped mine, just keep it in my pocket, and it has all these hairline scratches u can only see in the right light. I can honestly say I don't treat this phone any different than any of my others and I have never had this happen. Gs5, g3, g2, gs4, note 2. The only one I seem to remember doing this is the galaxy nexus. Anyone else having this problem? Guess I'm gonna need a screen protector. Any suggestions?

Scratched Front Screen topic

Hey everyone, i need your input on something.
Long story short my phone fell from my hands this morning from pocket height and slided on the wooden floor for around a meter or so. Due to dust on the floor i inherited a few scratches.

I was wondering if anyone tried any toothpaste/polish/windex etc on the front screen to smoothen a bit the scratches.

I haven't seen this anywhere so i'm not sure, but does the screen have any kind of coating similar with what the lens cover has?

Thanks for the input and have a great year everyone.
