my nokia every day gets dropped,hitting hard surfaces,infact today i raged and started hitting my nokia (lol).Thats pretty awesome for a smartphone.How hard is your nokia?
I have a Lumia 920 , few weeks ago phone slipped from my hands (my hands were sweaty ) and it fell on ball bearings (they are made up of steel ) , no dent or screen crack. There are minor scratches on the gorilla glass.
I own a L920. A couple of months back I dropped when pulling it out of my pocket and it landed on the side walk. I have a crack in the bottom corner of the screen and some scratches.
It's all in how the device lands. You've been lucky. Be happy.
