Proximity sensor always active
Hello guys,
I got a new Iphone 5s this friday, it has a loose power button and a strange proximity sensor.
The problem is that the proximity sensor is always on, when I use the phone.
So I can see the red light in dark rooms. If I touch the screen the red light gets brighter.
I think that isn't normal, because the proximity sensor should only be activated If I receive a call.
I have tried a lot of things like deactivating siri and the automatic brightness, but the sensor is always on.
The Iphone has the newest IOS 9.2 and I have tried several times restoring to factory settings with Itunes, nothing helps.
Is it a new feature from Apple or is the device defective?
Can somebody please check his Iphone 5s in a dark room or with a camera if his proximity sensor is always active?
Here is a picture of it:
