Phones in shirt pockets
I keep my Galaxy S3 Mini in the left breast pocket of my shirt. It has a curved back and a flat glass screen, so it only fits comfortably one way - with the glass towards my body. The trouble I find is that when someone rings me, and the screen goes live, I often accidentally answer by swiping with my left nipple. Similarly, if an alarm is set and triggers, for the next few minutes, until it goes to sleep again, every involuntary move on my part results in a series of bleats from inside my coat, which gets me some curious looks and smirks from nearby onlookers.
