You mean the proximity sensor is broken? The screen should be turned off whenever the device is close to your face. You can try clearing cache through recovery o see if that helps: power off. Hold home+volume down+power on until recovery loads. Use volume down to clear cache and power to accept. If that doesn't fix the problem then try a factory reset - be sure to backup your data first.
