The SetupWizardOverlay in Nothing phones is so inconsistent with the Android nature. On first setup, after that "what's new" screen it is prompting you to select your visual style. But the animation looks like it's switching to another app. (?) Also, sometimes when you unlock the phone, even after setup, it displays that visual style popup and if you choose something there, that you have to do, it RESETS your entire home screen layout and probably wallpaper. Nothing needs to fix this.
