iPhone screen goes black during phone calls and won't come back
Your iPhone has a proximity sensor that's supposed to turn the screen off during calls so your ear doesn't accidentally tap buttons. It's working as designed, but it's probably too sensitive or something is covering it. Try cleaning the small dot next to your front camera at the top of the phone. That's the sensor.
Your iPhone has a tiny sensor at the top of the screen that detects when you hold the phone to your ear. When it detects your face, it turns the screen off so your cheek doesn't accidentally tap buttons. This is normal behaviour, but if the sensor is dirty or something is covering it, it won't turn the screen back on when you move the phone away. Cleaning the sensor fixes this in most cases.

Skip — I just want a technicianCommon mistakes to avoid
- Not realizing the screen going black during calls is the sensor working as designed. It's normal, but it's not supposed to stay black if you move the phone away
- Trying to fix software when the problem is actually dirt or a screen protector blocking the sensor
- Assuming the phone is broken when cleaning the sensor first fixes it
Signs you need professional help
- You've cleaned the sensor thoroughly and removed any screen protector, but the screen still won't turn on during calls
