Phone is working great so far, like it - except for one annoying thing. I have a black and white skyline as my wallpaper. After unlocking the phone in a brightly lit area, a few seconds later, the wallpaper picture dims. If I am in regularly lit area, the dimming doesn't happen. If I change the picture to one of the crazy bright colour ones under wallpaper-stills any in the third row, they don't dim. If I change the wallpaper to wallpaper-live, the third picture then it dims. If I turn off auto brightness no dimming occurs. I'm using the same picture on an iPad Pro no dimming issue after unlocking. Anyone else seeing this? Super annoying me.
