How to disable automatic screen turn off during calls on Xiaomi?

Proximity sensor is the feature that makes your phone screen turn off automatically during calls. The idea of this feature is to prevent you from accidentally touching any buttons that might interrupt the calls. If you don’t find the Proximity sensor feature useful, follow these steps to turn it off:

1. From your device’s Settings, tap System apps > Phone > Incoming call settings.
2. Slide the Proximity sensor switch to the off position.
