I was in a changing room of a well known department store, when I dropped my phone from a shelf about 1.2m to the floor.
The floor was a hard polished ceramic floor tile. My poor Lumia 920 smacked into, obviously we know that acceleration due to gravity it will have impacted at 2.18 joules. Sadly the phone had no case on it. It cracked the floor tile. I feel bad for just nonchalantly walking away. Poor floor tile, never saw the butter side down phone coming
