How many dying people maintain manual dexterity and clear vision as the 'pilot light' flickers toward extinguishing?

Maybe there will be 'death app' where the last 'swipe' of the screen reveals a black screen?

Or maybe you can choose? The 'tunnel with a white light at the end of it' will be a popular choice.

Perhaps with a booming authoritative sounding voice shouting TURN. OFF.YOUR. PHONE!
