No sound during calls, chipped logic board
Dropped my iPhone 4, replaced the screen. Works fine apart from when making phone calls I can't be heard or hear with earpiece speaker phone Bluetooth headset or headphones. Sound works perfect for camera Skype and voice memos. I have tried everything, and i mean everything and now i am debating whether it is the fact that my logic board is chipped, seen in the picture. Can somebody tell me what the component is at that place where it is chipped and whether you think it may be the culprit. If so is there anything I can do? I am desperate!
Is this a good question?
