Karunamon is not asking for them to find a specific phone, just make a general announcement for everyone to double-check that their phones are off, and possibly to specifically cite interference as the reasoning.
Yeah. Maybe I'm just weird, but when I'm in a commercial jet loaded with a couple hundred people and 40,000 liters of jet fuel, and we're in those critical phases of flight, I don't want anything going wrong with the avionics on that plane. I don't want any malfunctions or errors, even if those malfunctions can be alleviated by the FA's making an announcement requesting that everyone shut off their phone.
Hearing, "if there's problems, we'll just have the FA's make an annoucement" doesn't exactly quiet my concerns. If we're going to be using our smartphones on airplanes I want it to be after thorough, deliberate, conclusive testing has been done that proves that the aircraft is safe to fly with hundreds of cell phones transmitting in the passenger compartment.
