Wasn't it be smarter to keep devices like proximity sensor off, for the battery sake? I can see it being on for the most of the time, and there is no option to turn it off. It is annoying.
I have never found specs for this phone, and I have been working with IR before so I had easily notice it. Just reported what I saw and what it looked like.

Wouldn't you think that proximity sensor could be implemented in normal camera instead of the sensor that is hidden under the black glass? It would extend battery life and drop the phone price.
Also there should be software update to let users switch it off. I don't like to see IR flashing on my eyes and I feel as this "proximity" feature is pretty useless.

I know that there are similar sensors in iphones and other smartphones, but others are stating openly that IR is being used for diagnostic data. The proximity idea is pretty daft in my opinion.
Also thanks for the replay tsac.
