why is my Iphone keep going dark?

Hi labman26,

We'd like to help provide the best assistance for your iPhone. If this is related to the device locking, you can follow these steps.

• Settings

• Display & Brightness

• Auto-Lock

• Choose how long you wish the screen to be active before Auto-Lock

If this does not address your concern, please elaborate a bit more about the issue so we can fully understand.
