problem hearing aid
Dear Madam / Sir
I have an iPhone 4s with 64GB and iOS 8,3. Recently I upgraded it on iOS 8,3 and a few minutes later it fell from my commode.
Although it has a cover case, the hearing aid doesn't work normally after this incident.
In all the calls I hear a noise like squeak either while awaiting reply from my interlocutor or during the conversation established.
Is this a hardware or a software problem? Can I tackle with this by my own?
Thank you,
Sincerely yours.
iPhone 4S, iOS 8.3
