Hello Mgibb223,

You mentioned seeing a blue light at the top of the screen, then the screen dims when you're outside. The brightness may change depending on the lighting conditions, when set automatically: Adjust the brightness and color temperature on your iPhone or iPad - Apple Support

With that said, this covers the iPhone icons and what they mean:

Do you recognize the icon or symbol from these resources? If so, these resources should provide you with the insight into what it is.

Hoping to hear back, take care.
