Why does the POCO M8s 5G screen not turn off when on a call?

If the POCO M8s 5G screen does not turn off when on a call, please refer to the following aspects:
1. The proximity sensing control for the POCO M8s 5G screen turning off during a call is achieved through touch screen sensing. When on a call, it is recommended that you keep the upper third of the phone screen close to your face for a better using experience.
2. Please remove any thick or non-original screen protectors, as they can interfere with the proximity sensor and cause incorrect screen-off behavior.
3. Please clean the top area of the screen to ensure the proximity sensor is not covered by dust, oil, or smudges.
4. Please restart the device or update the system to the latest version if the issue occurs abnormally outside of normal call conditions.
5. If the issue persists after trying the above steps, please contact after-sales service for further assistance.
