Hi everyone, Just purchased and unlocked one iPhone less than a week ago, found out yesterday that my iPhone's speaker was outputting abnormal sounds when I was changing some ringtones. The output seemed to be blasted (something like when your woofer's blasted) and I can't hear anything at all. Suspects that the speaker is damaged (though I have only used it less than 10 times to play songs via the speaker). The iPhone otherwise is still working fine. A friend told me that I might have to open the phone up and replace something (no I don't know what is there to replace), but I refused due to the fear that I might brick the phone later. Anyone has any suggestion on how this problem can be rectified ? Thanks for stopping by !
