Update on some testing.
I just finished a testing cycle where I changed to dark mode, changed wallpaper, took a picture, changed to white mode, changed wallpaper, took a picture and repeat.
I managed to do 50 changes (50 dark / white mode & 50 wallpaper changes). All wallpaper changes were made through a shortcut action, and it’s a random wallpaper from a list.
So far no problems, so I have to conclude that time is an imperative issue here.
I restarted my phone at about 8Am my time, I’ll try to take a picture every hour or so and update on the finding.
Another thing worth mentioning: I have an automation that changes wallpaper automatically every 5 minutes, so the phone will keep changing throughout the day
