XZ proximity sensor always on

[ahyik]

Hi,
My phone's proximity sensor is always on(can notice a small red light, especially in dark), when the screen is on. Is this the correct behavior? I thought the proximity sensor should only works when making call.

Thanks!

Yeah, the sensor is on to make adaptive brightness work effectively and correctly as far as I know. You can check this: enable adaptive brightness, cover and sensor and see the glider going down.

Yeah, you are correct. No more red light after disable the adaptive brightness. Thank you very much!

I disabled adaptive brightness and the red light still on

yes that is true the problem is the infra red emitted is hazardous  or not by simple electronic parts we can confirm that ir radiation is always toward eyes
