A portable electronic apparatus is disclosed. The portable electronic apparatus comprises a casing, a first displaying module, a second displaying module, a communicating module, a sensing module, and a controlling module. The first displaying module and the second displaying module are set on a first face and a second face of the casing respectively. When the communicating module receives an incoming call signal, the communicating module generates a starting signal. Then, the sensing module receives the starting signal and performs a sensing procedure to generate a sensing result. The controlling module selectively displays an incoming call information related to the incoming call signal on the first displaying module or the second displaying module according to the sensing result.
