sorry but this is an english site only.Hello everyone. When I put my huawei GT3 in speakerphone mode during a call it whistles loudly and there is an echo. Does anyone have any idea of this failure. A big thank you to your réponse.Bernard
yeah i still think it is a hardware issue and not a software issue. i could be wrong. i'm not familiar with your phone or how cellular works overseas. but here in the US (i'm in california) on the Sprint network, we have the option of updating prl and profiles. both of those are for having a cellular connection as well as having a data connection. sometimes updating those help with reception and internet connectivity.no noise went phone to ear , just went speaker.thank for your answer
