                                  how is it possible that when i go somewhere where the network coverage is weak smartphone always has a weak signal sensitivity one bar or none at all but on checking the old 2G phone its always full or just one bar shy away from whenever am traveling upcountry i tag along my old school phone.
                                  NB: I have had several brands of smartphones and the outcome is the same

                                                    @M Uzair Arif how does the waves not lose considerable amount of energy? Because even inside a home voice coming through the phone doesn't get distorted or reduced very often?

                                                    there are different models for indoor and outdoor propagation of electromagnetic waves. but the basic models are reflection, scattering and diffraction.
