Pictured is my Nikon 300mm, f2.8 VR lens I use for wildlife photography. I paid $4,000.00 for it years ago. New ones are closer to 6k now.
As advanced as cell phone cameras have become, there is no way a cell phone camera lens and sensor can compare when it comes to resolution, depth of field, ability to stop action, or low light ability. Not even close.
But, as others have said, modern cell phone cameras work well for most casual users, and the camera (phone) you have with you works worlds better than the heavy, bulky gear you don't.
I am going to guess that one aperture value is the one your camera is capable of, the other is what it actually chose for the picture based on Shutter speed and ISO / lighting available.
