Hullo, first I would like to thank you for prompt delivery and careful mail packaging of the Mobile phone I received today, very good. There is a major problem with the phone ability to to send voice sound to another phone while making the call. - The person on the other end of the call only hears the sound of "rushing air" in normal phone call mode but when the external speakers or ear buds are attached the sound is great. - I have tried all settings applicable to phone speaker sound but there is no improvement. - Could you please come up with a suitable remedy for this problem, I'm sorry to have to report this to you. I don't think photos are needed because the phone is brand new and not at all damaged. Regards Ross England
