{"package_name":"com.android.wallpaper","label":"Wallpaper and style","device_count":40,"observation_count":74,"user_facing_count":0,"first_seen":"2025-05-08T17:55:42Z","last_seen":"2026-09-18T07:11:21Z","guidance":{"summary":"The \"Wallpaper and style\" app: the screen users reach from Settings or from a long press on the home screen to change the wallpaper and, on builds that include the theme picker, the wider personalisation options that sit alongside it. It is built from AOSP. Both the WallpaperPicker2 and the ThemePicker projects declare package_name \"com.android.wallpaper\" in their Android.bp, with ThemePicker listed as overriding WallpaperPicker2, so a device ships one app under this name rather than two. In our sample it is signed by each vendor's own platform key, which is what you would expect of an AOSP app built into the system image.\n\nVersion note: the personalisation surface this app fronts is tied to the Material You work introduced in Android 12, and AOSP's own guidance describes the theme picker as where users engage with those personalisation capabilities and wallpaper colour extraction. What this package offers therefore varies with the platform version and with whether the OEM built the theme picker into the image at all. Some vendors ship their own app instead: Samsung's equivalent carries the same \"Wallpaper and style\" label under com.samsung.android.app.dressroom and is documented separately on this site.\n\nFor Android Enterprise, EMM and kiosk use, the practical control is policy rather than package removal: Android Management API exposes setWallpaperDisabled (\"Whether changing the wallpaper is disabled\"), which blocks the user from changing it while leaving the app in place. On a tightly locked-down kiosk the picker is normally unreachable anyway. Disabling the package removes the wallpaper and personalisation entry points from Settings and the home screen, which is cosmetic but visible to users, so prefer the policy control.","safe_to_disable":"caution","sources":[{"title":"WallpaperPicker2 Android.bp - Android Open Source
