Small camera on bottom of lock screen allows quick access to my camera.

But is not my iPhone less secure. Once I disabled my camera on lock screen, I no longer had access to camera app. I love everything Apple for past seven years. I cannot believe that I cannot figure this out. Is there anyway to keep phone locked and have Apple camera app to use. I know I can purchase camera app, however , I really prefer to use apples app.

since screen time appeared in iOS 12, I really have not needed it. I know only pictures can be taken, but I really do not care to have someone use my camera app. Possibly another person cannot access my personal info, but it seems like I am opening up my phone to another person. Hopefully there is a work around for my concern.
