I often have my phone on a nearby surface, table or chair. Even if face down, my case maintains a slight clearance letting enough of the light out to be noticed at a distance. I believe person who initially showed me this feature kept her phone in a open-top handbag. Again, whatever the phone orientation, the reflected bright notification flickering would often be noticeable. The notification flashes are somewhat negative distractions in dark places like a car at night, or theater, if the phone has been left on lap or seat. Also, it may sometimes give third parties the mistaken impression you're taking photos when you're not.
