Follow a guided phone earpiece and proximity-sensor check during a real call.
With permission, make a normal call to a trusted person. Listen at your ear, then bring the phone near your ear and check whether the display turns off and wakes again when moved away.
This is a manual check in the phone dialler. The website cannot listen to the call or independently read every proximity sensor. Settings and screen protectors can affect the result.
Use the phone dialler yourself. Call charges may apply; never use an emergency number for testing.
