Check to make sure there is no pocket lint in the headphone jack. Lint, dirt, and other debris can send mixed signals to the phone causing similar issues. I like to use the pro picks that I purchase from ifixit for this task and a can of air if needed.

Also, the iPhone 4 in many cases is still under warranty - it's something to always check out on newer devices.
