I think those “consumer itches” probably stemmed from 1990s American action movies in which the original of this style of phone (Motorola MicroTac I think?) seems to be almost universally used.
1. pull buzzing phone from pocket, purse, etc.
2. extend antenna
3. flip cover open (the really cool ones had a spring loaded cover opener activated by a side button)
4. optional: look at the display before answering
