Red light at the top of my 925

[ubi sunt]

Hello, I have Lumia 925 for about a week now. I have a screen protector film on it. I was playing with it from its top right corner and I noticed that the red light on the top right corner is on. It is not blinking or anything it is just always on when i have the screen locked, and it is clearly visible. When I unlock the screen it turns off. I know it is the proximity sensor, but can anybody tell me why it is always on? Is that normal and what can I do about it?

I have this too, I have Glance Screen set to "Peek" mode and it turns on when my phone is locked

Mine does the same thing, I'm pretty sure it's normal.

I'm not sure what it's used for, but I noticed that the red light is brighter when the glance screen is turned on or on peek mode. Guessing it's somewhat related to that

Oh... ok.. I thought maybe there was something wrong with its having a screen protector film on it. But there's nothing to worry about then... Strange thing is, I havent noticed that light till now...
Thanks for your replies...

You've answered it right there. In order to detect you motion for Glance/Glimp Peek mode, the phone needs to turn on the proximity sensor. That's the red light you see.

There is also an audio setting to ring louder when in purse/pocket. That also uses the proximity sensor. So if you see it on even with peek disabled, it could be that.
