Oof, that hurts just reading it. Glass and tile are sworn enemies and I swear the drop never even has to be far, four inches might as well be four feet. It's like the universe keeps a running tab on expensive stuff and tile floors are how it cashes in, phones, plates, cups, you name it. Same thing happens with screens on concrete and anything fragile near a hard floor, one tiny slip and boom. Sorry about your panel, that one really stings for 89 bucks.
