{"package_name":"com.sec.android.dexsystemui","label":"Samsung DeX System UI","device_count":17,"observation_count":33,"user_facing_count":0,"first_seen":"2025-05-05T17:48:10Z","last_seen":"2026-08-08T18:03:34Z","guidance":{"summary":"Recorded as \"Samsung DeX System UI\", this is a Samsung system component that by its label and package name belongs to Samsung DeX, the desktop-like mode Samsung describes as run from a Galaxy phone or tablet \"with or without a wired connection\", on an external monitor or, wirelessly, on a TV that supports Miracast screen mirroring. Samsung's DeX page documents the feature rather than naming this package, so the tie to DeX rests on the label and package name and is an inference. Its role within DeX is also inference: this site records it requesting system-UI-level permissions such as STATUS_BAR_SERVICE, INTERNAL_SYSTEM_WINDOW, MANAGE_ACTIVITY_TASKS, BIND_QUICK_SETTINGS_TILE and INJECT_EVENTS, which is consistent with a system UI role but does not establish one, plus permissions named for com.sec.android.app.desktoplauncher (labelled \"Samsung DeX home\" on this site) and for com.sec.android.app.dexonpc. Requesting permissions named for those packages suggests interaction with capabilities associated with them, not that they depend on it, and this site aggregates permissions across observations rather than per build, so which builds declare each of them cannot be established. This site records it as not user-facing in any observation.\n\nOn this site it is recorded only on Samsung phones and tablets, on devices reporting OS API levels 33 to 35. Where this site holds signer data, which covers 3 of the 17 devices recorded, it is signed by a Samsung OEM key that also signs the Android framework, a platform-level key. This site's roll-up reports a single version name, 3.0.06.20.\n\nVersion note: Samsung's DeX page states that launching DeX with drag and drop, Multi desktops and Extended mode \"require Android 16 or higher\", so the DeX feature set differs by Android version. This site has not recorded this package on any device reporting OS API level 36 (Android 16) or later, while the related DeX packages documented separately on this site are recorded up to API 36. That absence may reflect this site's sample rather than a change in the firmware, so whether the package is still shipped on Android 16 builds could not be established. Samsung's Knox documentation shows the same version sensitivity from the management side, marking several DeX policies as not supported on Knox 3.12 or later and one as requiring Knox 3.14 and higher.\n\nFor Android Enterprise, EMM and kiosk use, Samsung's Knox documentation states that \"DeX is not supported on devices running in Kiosk mode or Lock task mode\". Where DeX is in scope, the Knox Service Plugin DeX policy is the documented control, including \"Allow DeX connection\" and a list of apps disabled in DeX mode. If this package is the DeX system UI its label indicates, disabling it instead of using that policy could affect DeX and connected-display behaviour; the effect was not verified here, so test on a device before applying it to a fleet.","sources":[{"title":"Samsung DeX -
