Speakerphone automatically on when answering calls

[AFguy]

For some reason the speakerphone is automatically on everytime I answer a call. I have to turn it off every time.  I looked all through the settings but couldn't find anything related.  Anyone else have this happen?  Any ideas what it might be??  Thanks.

The speakerphone is only be available while on a call. Once the call is ended the speakerphone is disabled. While on a call, select the Speaker symbolto enable / disable. To resolve your issue, try a soft reset on your device. Remove your battery while your device is powered on, wait about 30 seconds, replace battery and power on your device.

Is it while it's in the car dock?  Believe it automatically defaults to speaker when in the dock.
