Try this:
1. Grab a earphone which has a mic on it.
2. Plug your earphone in your device and make sure that you keep your device unlocked.
3. Long press power/answer button on earphone for nearly 4-5 seconds and then immediately unplug your earphone with out releasing the button.

Either something is stuck in the earphone jack, or the jack is defective. That trick works if something small is stuck in the jack and plugging in an earphone dislodges it.
