Purple flash when closing apps iOS 26.1 New issue on iPhone 16 since update to 26.1: Screen background flashes purple when closing an app, just after swiping 'up' as the app slides off the screen. The background turns so briefly purple that I can't get an image of it. Nothing else in my wallpaper or other color selections is purple. (I'm not a fan of purple.) Not a big issue as long as nothing else is happening; just a curious one.

Force-quit the app → reopen. If it persists, uninstall/reinstall.
