Waterproofing...
... became almost essential, imho, as soon as some phones were waterproof.
It rains a lot in the UK. In the old days I sometimes had to resort to wrapping a phone in a dog poo bag (unused!) to ensure it wasn't destroyed by the time walkies finished. (I also found you can operate a kindle in a sealed freezer bag!).
Then there's using the phone in the kitchen --- or the bath.
When I got my original Xperia Z1 one of the girls at the yard asked why i hadn't bought an iPhone - I still remember the look of terror on her face when I 'accidentally' fumbled it and dropped it into the bucket of water she was carrying.
