...........until I changed the wallpaper? Explain that one?
I guess it's only when *I* change the wallpaper on an iPhone... somehow *I* break it and nobody else's iPhone would do that.
Not sure if you have done this yet as I don't recall seeing it but can you provide a link to the wallpaper that causes you issues? I'd like to see how it impacts mine and see if it's the same as you report. I use wallpapers from my 6S Plus days and don't see any issues.
