I hate call screening. I never activate it on purpose, the phone's screen decides to wake up while it's still in my pocket and let my thigh press the button for some reason. Then I pull the phone out of my pocket, look at the caller ID, and see that a robot is screening an important call from my boss, and the button to actually answer the call is greyed out until the robot is done harassing my boss. Or my doctor, or my therapist, or my bank. I've had important people I was expecting a call from hang up because they reached a robot instead of me and assumed it was a wrong number. It's a terrible first impression to make when I've applied for a job and this robot decides to harass my potential new boss.

If they made the call screening button a slider, it would reduce the butt presses by 90%
