Mine does that too, although I have a different model. An alternative is to purchase a widget which locks your screen for you while you are on calls. I have a button on my phone (power button on top) that when I press it once it blanks the screen. I have to do that for every call regardless because I am constantly muting, hanging up, accessing other apps, while I am talking on the phone. The sensor is not the best and don't forget ears can get dirty/oily too which will affect the sensor's ability to work as well. Keeping the area around the sensor clean as possible helps. If you have the button, though, use it. Otherwise there might be a widget or app which automatically blanks out the screen when you answer a call and pulls the screen back up when the call is complete. Hope this helps.
