Hello, I want to buy an iPhone which has a problem : During calls there is no sounds (the caller don’t hear me and I don’t hear the caller) even if we put the headsets or the loud speaker mode… But when we use the net or a VOIP app it’s work fine… So, I want to know only if it’s a motherboard problem or changing the mic,speaker…etc will fix this. Thank you.
Help me please ! Have you any idea ! Motherboard or Mic
