This is Samsung's Clock app, made by Samsung Electronics. Its Google Play listing, published by Samsung Electronics under this package name, describes it as providing Alarm, World Clock, Stopwatch and Timer features, and Samsung's support article on the app adds a Bedtime mode that turns the screen greyscale and mutes calls and sounds while the user sleeps. Samsung's Common Criteria application lists for the Galaxy Note8 (N950U1) and the Galaxy S20 5G (G981U) record this package as "Clock" at versions 10.0.00.60 and 12.0.00.54 respectively. Its English label in our sample is "Clock", with localised equivalents in other locales. Version note, and the key point for managed fleets: Samsung's Knox knowledge base article KBA-1029 states that before One UI 5.1.1 the Samsung Clock app was considered a system app that an EMM could install with the enableSystemApp() method, but that on devices which come preinstalled with One UI 5.1.1 or later it is no longer considered a system app and is only available from Google Play. The article lists the Galaxy S23 series and all later models as affected for the Clock app, and says the fix is to deploy it through Managed Google Play. So on those devices an EMM that relied on enableSystemApp() to make Clock available needs to deploy it as a Managed Google Play app instead. This site still records the package on devices reporting API 28 to 36; these records do not establish how each of those builds classifies it. Where this site holds signer data, it is signed by Samsung OEM keys that also sign the Android framework, a platform-level key; two distinct Samsung keys are recorded. This site's roll-up reports versions from 12.1.25.0 to 12.5.07.13. For Android Enterprise, EMM and kiosk use, disabling it would remove the alarm, timer, stopwatch and world clock features Samsung documents in this app. On a dedicated device that does not need those features, test on a single device before disabling it fleet-wide. Treat with caution.

• 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 (580 packages, 11729 observations).
• Its largest observed manifest declares 88 permissions: 8 runtime (user-granted), 22 signature or system-level, 13 install-time and 45 vendor or uncatalogued.
• APK size ranges from 20.8 MB to 51.2 MB across the reporting device profiles, so the build differs substantially between them.
• Reported as an updated system app in 5 of 14 observations - a newer build was installed over the one in the system image. Multiple observations can come from the same device profile.
