Two screenshots of the lock screen on my iPhone 17 Pro whose difference confounds me. In one the contrast is good and I can read the numbers on the pad, but the time and battery status are hidden. In the other, the key pad is pretty much invisible but I can see the time and battery. I have no idea how to trigger the contrastier one; it just sometimes does this.
Is this phenomenon known? Explicable? It's as if the new UI is sometimes ashamed to show how unreadable it is and compensates before hiding again.
Somebody made this happen. Any idea why?
