com.samsung.android.dynamiclock Copy

Labelled "Wallpaper services" on this site and in Samsung's own Galaxy S20 application list, this is the Samsung component behind the Dynamic Lock screen, and Samsung names the package directly. A Knox Manage knowledge base article on restricting the "Dynamic Wallpaper Service" identifies it as com.samsung.android.dynamiclock and warns that "if a device user can access the device's settings, the custom wallpaper can be overridden by setting a dynamic lock screen". Samsung's consumer support pages describe the same feature as "a service that automatically updates and displays images of animals, landscapes, etc. every two weeks on the lock screen", and tell users to turn it off at Settings > Wallpaper > Wallpaper services by selecting None, then switching off "Swipe left for info page". The permissions this site records fit that picture and are the reason it is worth a second look on a managed fleet: INTERNET and ACCESS_NETWORK_STATE alongside DOWNLOAD_WITHOUT_NOTIFICATION, SET_WALLPAPER and a Samsung keyguard image permission, plus POST_NOTIFICATIONS, INSTALL_SELF_UPDATES, Google Cloud Messaging receive and the Google advertising ID permission. This is a component that fetches imagery over the network and puts it on the lock screen of the device, and it can update itself. Version note: the package does not appear in Samsung's Oreo-era Note9 application list but does appear in the Android 11 S20 list at version 3.3.00.55, and this site records versions 3.3.03.66 through 3.8.00.14 with a target SDK from API 30 to API 36, so it is actively developed. Samsung's own instructions caveat that the on-device menus may vary by device model and software version, and no source we found sets out how this feature's naming or placement has changed across One UI releases; that gap is stated here rather than left to read as evergreen. For Android Enterprise, EMM and kiosk use, decide deliberately whether rotating network-sourced imagery and a swipe-left information page belong on the lock screen of a corporate device. Samsung documents the supported way to stop it on a managed fleet: add com.samsung.android.dynamiclock to the "Block Certain Apps from Running" app list in the Android Enterprise app restrictions policy, after which, in Samsung's words, "device users can no longer override the custom wallpaper by setting a dynamic lock screen". Where the aim is to fix the wallpaper outright instead, the Android Management API has a setWallpaperDisabled policy. The rating below follows from Samsung documenting the blocking of this specific package, and stating the consequence of doing so, alongside the supported off switch in Settings.

• Signed by the device maker's own signing key (Samsung), so it is an OEM preinstall, but 2 different certificates appear across the fleet, so OEMs ship their own builds of it. It also signs the Android framework, so it is a platform-level key on its device(s). Inferred from the certificate appearing only on Samsung devices (508 packages, 10196 observations).
• Its largest observed manifest declares 39 permissions: 3 runtime (user-granted), 11 signature or system-level, 11 install-time and 14 vendor or uncatalogued.
• APK size ranges from 7.6 MB to 35.6 MB across the reporting device profiles, so the build differs substantially between them.
• Never reported as user-facing, so it runs as a background or system component rather than an app the user opens.
