Microphone not working on RP2 after using Microphone dead

Hello, one strange thing happened with my RP2. I have been using headsets (inears) when driving ever since I bought the phone. Yesterday after got home and pulled headsets of the phone I noticed that my microphone is not working. When I reconnect the headsets to the phone the other person can hear me so the microphone is working. But as soon as I disconnect the headsets the microphone is not working. I checked everything and it all seems fine. So I had no other choice but to set the phone back to factory reset. Still after I did that the microphone is only working with the headsets. I did not drop the phone and the phone is updated to the latest Android and latest firmware that I received from Razer. I tried the phone in safe mode and the money c is not working. Tried disconnecting the OK Google still nothing. The mic is only working when I record a video,then I can hear my voice. Thanks in advance for any help
