My phone screen is off or the dark does not work when making outgoing calls

My phone screen is off or the dark does not work when making outgoing calls, but I just bought not long ago only 1 week.

Sorry @Sria2 are you saying your device screen goes black on calls or something else?

[Sria2]

I do not know, when making a call screen does not work; it goes out or die. I recently experienced this sort

@Sria2 The proximity sensor is very sensitive, try to clean it and also make sure there is no screen protector covering it.

[Sria2]

I just used it can tell how?

In addition to what @alexdon said, could you try to see how your device behaves in Diagnostics? Go to Settings > About phone > Diagnostics > Test > Ear proximity. In this test, the device should only vibrate when covering the sensor (located next to the SONY-logo at the top of the front). Does it behave that way?

Also, try to see if the same occurs in safe mode.

when I checked there are problems NFC services are not running, as where cope

[Emir1]

What do you mean, in a bit more detail? Did you get an NFC error message while performing the Diagnostics test, and if so what did it say more precisely?

[Sria2]

when performing diagnostics information contained NFC issue is not going well.

[Sria2]

and when I open the application contained information support NFC services do not operate properly.
