The black screen after calls and listening to audio clips from WhatsApp

Hi LUQMAN3,

Thanks for visiting the Apple Support Communities.

If the issue is specific to WhatsApp, see if the steps outlined in the Apple Support article If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open - Apple Support help. They're designed to address issues that are specific to one individual app.

If you are finding that the display will not come back on when moving the phone away from your face during calls in other apps, specifically the Phone app, this could be an issue with the proximity sensor. In this instance, you will want to get in touch with Apple Support directly. They will have access to the necessary tools and resources to help with this sensor. You can do that here: Get Support.

Have a lovely day!
