I have a Curve 8300 in perfect working condition except when you make calls even on speaker phone it sounds like aliens. That is really the only way to describe, it sounds really weird. I have tried to search for the answer but no luck. Also speaker sounds perfect for anything else like music or ring tones just while in a call. I have already tried to replace the ear piece speaker and also wiped the OS and reinstalled. Still no luck. Any ideas????
