To be more specific, here are the problems I am experiencing:
1. speaker makes loud, screeching noises during calls
2. microphone seems to cut off during some calls
3. camera freezes from time to time while viewing pics
I'm very sorry to hear your having issues with your droid charge. I would be happy to look into this with you. Did this start after an application was downloaded? Please try powering the device in safe mode and retest. Here's a great link on how to power on in safe mode: http://bit.ly/QfGvNp
Please let me know if this helps, if not we will try some other troubleshooting steps.
