While the interference from one mobile device might be negligible, the combined interference from several devices could potentially disrupt the airplane’s communication and navigation systems. This is more of a concern during critical phases of flight, like takeoff and landing. Notice I said potentially. It is unlikely to occur, but since 70+% of all aviation accidents occur during takeoff and landing, they use an abundance of caution.

Is there any evidence of this ever actually happening?
