iphone: Can't understand the voice of telephon-partner
Hello,
my iphone4 is too quiet to understand any partner on phone-Call (with the external speaker and Headphone it Works well). The iphone runs the actual IOS-Version. We have tried to clean the internal speaker-hole, restart the iphone but the problem resists. Can anybody help us?
Thanks a lot,
Mike
