Activate the proximity sensor of the iPhone
Lucky for you (or bad luck, it depends on which point of view you consider it), come on iPhone there is no possibility to disable the proximity sensor, unlike what happens, however, on Android. This means, therefore, that there is no need to know how to activate the proximity sensor of the iPhone, for the simple reason that this is active by default.
If, during a call, you try to hold the iPhone to your ear, the phone screen should automatically go blank, indicating that everything is working as it should. If this does not happen, however, there may be some hardware or software problem related to the operation of the sensor in question. In this case, I suggest you check the status of the proximity sensor and if necessary try to solve the problems by adopting one of the solutions indicated in the last chapter of the guide.
If, on the other hand, the proximity sensor does not seem to work because when you lift the iPhone the screen does not activate, most likely you have deactivated the function Raise to activate (which, for the record, is available on iPhone 6s / 6s Plus and later and does not use the proximity sensor to work, but the movement coprocessor and the accelerometer): to reactivate it, go to the menu Settings> Display and brightnesssposta su ON the switch lever located in correspondence with the item Raise to activate And that's it.
