com.samsung.android.ConnectivityUxOverlay Copy

The sibling of com.samsung.android.ConnectivityOverlay above and the same kind of component: a resource-only Runtime Resource Overlay shipped in Samsung firmware, recorded at roughly 12.9 KB to 17.0 KB with no launcher entry and, in this case, no declared permissions at all. As with its sibling, the platform side of what such an overlay can set is published as the ServiceConnectivityResourcesConfig overlayable, which covers the captive portal server URL, the bad-Wi-Fi handling switches noted above along with their version caveat, protected networks, and the no-internet and network-switch notification settings. What Samsung does not publish is what separates the two overlays, so the "Ux" in the name should not be read as a sourced description of its contents. The two differ in this site's sample in ways worth recording rather than interpreting: this one declares no permissions where its sibling declares POST_NOTIFICATIONS, and it is recorded with version names 12 through 17 and target SDK 31 to 37 where the sibling spans 11 through 16. On the plain reading of the name it carries the user-experience facing part of the same connectivity configuration, but that reading could not be sourced. Version note: the version and target SDK spread above shows the overlay tracking Android 12 through the Android 17 era rather than a single release. Whether its contents changed across those releases could not be sourced. Provenance: recorded only on Samsung devices, signed with Samsung certificates marked as also signing the framework. For Android Enterprise, EMM and kiosk use the position is the same as its sibling: no enrolment or policy role, nothing user-facing, and no hardening benefit from removing it. Disabling it discards part of the build's connectivity configuration, so it is best left enabled and only considered with careful per-device testing.

• 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).
• Never reported as user-facing, so it runs as a background or system component rather than an app the user opens.
