What does the proximity sensor do?

[#1]

Im using SE Arc S (LT11a). Brought it from Thailand. I find a proximity sensor and the light sensor on my phone. It is working fine in the service test

(*#*#7378423#*#*). How is the proximity sensor actually work and is it  automatically activate or have to do it manually? If so, how please?

Anyway, from my personal use, I didnt feel any different it adjusting the brightness especially during the night time. It is still too bright. Do i miss

configuring something or should I download any extra apps to utilise it? Thank you very much for your kind attention, advise and help in advance. :smileygrin:

Hi,

Proximtiy sensor is used to turn off the screen when you r on the call. It will work when your face touch on the screen.

Well, You r speaking about ambient sensor. Dont get much confuse about that.

Simply you can adjust the screen brightness by manually. Settings > Display > Brightness.

Or you can download the Brightness level widget.
