iPhone 4 Speakerphone does not work
I have been around what seems like the entire internet looking for reasons why the speakerphone on my iPhone does not work. I can take a call and the caller can hear me but the moment I put it on speakerphone they cannot hear me any longer.
I have tried the various resetting options, cleaned out the small noise cancellation hole near the headphone jack and still nothing.
Voice memos work as well. I believe speakerphone uses a small mic that is attached to the power cable within the iphone 4. Just looking for clarification if I am correct that changing the power sensor cable will likely remedy the speakerphone issue.
Is dit een goede vraag?
