unable to hear people when there phone
when people phone me i can hear thenm but they cant hear me i have an iphone 4 so would i beable to use parts from the iphone 4 to fix my iphone5
No, parts from the iPhone 4 are not compatible with the 5.
Start by using a sewing needle and some air duster to clean on the small holes on the bottom side of the phone near the audio jack. If this does not affect operation, I would open the phone, and check to make sure the dock flex connector is seated properly. This connection is located to the bottom right of the battery. If it is seated and the microphone still doesn't work, then you will most likely need to replace the dock flex. This flex cable contains the microphone. It's a very simple repair, just keep track of screws and be sure the move the microphone cover and the ground strap on the audio jack over to the new flex. Hope this helps!
