Requirements specification
1. It needs to survive being dropped in the pub toilet (helpful if it comes with a couple of readily replaceable phone cases, a pair of tongs, some disinfectant wipes + a clothes peg for the nose - this accessory kit is likely already available on aliexpress.).
2. It needs to be waterproof to a depth of approximately 6in (this should also cover case 1, but assuming the phone is at my ear, and the depth of water above it is greater than 6in then I have other problems such as drowning that are likely more pressing.). I'm ignoring possible minor usage problems at lesser depths (cue well known Michael Jackson song - I'm forever blowing Bubbles).
