Then I would hover my hand over that proximity sensory (and only that sensor) to see if the screen goes black.The proximity sensor is a small little sensor, usually on the top of the phone next the logo or speaker you hold up to your ear.The sensor is supposed to recognize when you hold your phone up to your ear, so that the phone will lock (turns on the black screen), then you wont accidently press keys with your cheek when talking to other people on the phone.After youre done with your conversation and remove the phone from your ear the sensor is then supposed to unlock your screen and allow you to end the call.
Here are some codes that might give you the option to run a test on the sensor if youre having this issue on a Smartphone.

After that Ive been having a black screen when calling and the only way I found to end a call is to connect my earplugs. I have tried the codes you provided, but no menu seems to pop up, so I was wondering whether there was something else i might be able to do. I also wonder whether its the proximity sensor thats broken or the broken glass that is in front of it and if theres a way to check this. This way I know whether I also should have the sensor fixed and not just the screen. Since you cannot get the codes to work (these star codes are available on fewer and fewer smartphones) here is what I would do.
