* Your device doesn't have it as per the manual you can download from [here](https://catphones.com/en_gb/support/s41-support) 

* But it does the Ambient  light sensor as mentioned [here](https://www.androidauthority.com/cat-s41-review-815500/)

Reasons for not enabling it are best known to OEM and you can ascertain from them and also request for inclusion in future updates (unlikely they would heed your request)

**Edit**

As suspected it doesn't support. [Chat](https://www.catphones.com/en_gb/support.html) screenshots
