Adapt sound, made by Samsung. Devices in our sample show this package under the label "Adapt sound", which is Samsung's personalised audio feature: it lets a user pick a preset matching their age group or take a short hearing test, then shapes playback to the resulting profile. Samsung's regional guidance reaches it at Settings, Sounds and vibration, Sound quality and effects, Adapt sound. Samsung says headphones must be connected to use parts of the feature, and recommends connecting headphones and working in a quiet environment when taking the hearing test. In our sample the package is signed by Samsung's platform key, and its recorded permissions include the Bluetooth ones, which fits a component that has to work with connected headsets. Version note: we did not find a documented change of role for this component. The builds recorded on this site report target SDK values from 30 to 37, which is a long spread rather than a sign of a role change, and Samsung's description of the feature has stayed consistent across the pages we read. The cited instructions do differ on where to find it: one gives the Sounds and vibration menu path above, while Samsung's current US page simply tells users to search Settings for "Adapt sound". We could not source which release, if any, moved it, so search Settings rather than relying on a fixed path. For Android Enterprise, EMM and kiosk use we found no documented enrolment or policy role for it, and nothing in the sources points to it holding corporate data. It is rated with caution for a different reason: this is a hearing-accessibility affordance, and on a corporately owned device given to a named user, removing it takes away an audio adjustment that some users will rely on. On a kiosk or single-purpose device with no audio output the user-facing feature has little to offer, but the package-level effect of hiding or disabling it is unverified: we could not source what it does to the Settings entry or to anything else that reads the sound profile, so check the Sound quality and effects screen on a test device before applying it widely.

• 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 13 permissions: 4 runtime (user-granted), 3 signature or system-level, 4 install-time and 2 vendor or uncatalogued.
• Never reported as user-facing, so it runs as a background or system component rather than an app the user opens.
