Hi. Complete newbie here. I had to replace the screen on my Defy recently. After the screen replacement (that went surprisingly well) I started having problems with the proximity sensor, when I checked a video on you tube I see what looks like a rubber seal over the led/proximity sensor that, like an idiot, I seem to have lost the one on mine. I'm attributing the sensor issues to the lack of this surround (the screen turns off immediately on making a call), this isn't the end of the world but I am also worried about water/dust protection. Does anyone know where I might be able to source a replacement? any help would be much appreciated.
