Help When talking on my phone the screen will go dark aftPhone disconnects when talking and screen closes

[srfoot]

When talking on my phone the screen will go dark after a period of time. I can continue to talk but if I press the side button to open the main screen the call gets disconnected.

How do I correct this?

Thank you.
