Would I very easily, definitely and immediately notice if there were any cracks on my iPhone screen? How would I know if my iPhone screen had a crack in it? Would I see or even notice it while using and looking at the display or is it something you wouldn’t miss?

Will having/using my iPhone near beads or jewelry made with beads and metal craft wire (like rings, necklaces, etc) crack or scratch my iPhone screen just from being near them? Especially if a bead fell on the screen. I have a screen protector. I have the iPhone SE 2020
