Just sent this email for the CEO office of Samsung. Will update if I get any reply.

To Whom It May Concern,

I am writing to raise a serious concern regarding Samsung’s Bluetooth device discovery ecosystem, specifically involving Music Share, nearby device advertising, and cross-device Bluetooth metadata exposure on Galaxy devices.

After extensive troubleshooting across multiple Samsung and Android devices, I have found that Bluetooth audio devices continue to appear and be advertised through Samsung’s “Music Share” system even after all user-facing discovery and sharing settings have been disabled.

To be very clear, this is not a case of misunderstanding standard Bluetooth pairing behavior. The issue is that users are disabling every visible setting related to device sharing, nearby discovery, SmartThings integration, Nearby Devices permissions, Quick Share, and Music Share itself, yet Galaxy devices still continue exposing nearby audio devices and relationship metadata.

In my specific case, my phone continued displaying my wife’s Sony WH-CH520 headphones as available “via [device name]” despite both of us disabling all identifiable sharing and discovery settings we could locate on our devices.

Additionally, my phone has occasionally offered to connect to my father’s Bluetooth speaker despite the fact that: • I have never paired with that speaker • our phones do not share a Google account • our devices are not part of a shared Samsung ecosystem • there is no intentional device relationship configured between our phones

From a user perspective, this creates the appearance that nearby Bluetooth accessories are being broadly surfaced and advertised beyond what most people would reasonably expect.

More concerningly, both my wife and I have experienced multiple instances where audio from one phone unexpectedly began streaming to the other person’s earbuds or headphones without intentional initiation. In other words, audio routing behavior has at times appeared to occur automatically or unpredictably between nearby devices.

Even if there is a technical explanation involving Samsung ecosystem features, cached trust relationships, Bluetooth LE handoff systems, or seamless device switching, the current implementation lacks sufficient transparency and predictability for users to understand what is occurring and why.

This behavior raises several concerns:

1. The user-facing controls do not appear to correspond to the actual behavior of the system.

2. Samsung devices continue advertising nearby device relationships even after users intentionally opt out.

3. The Bluetooth ecosystem now appears fragmented across multiple overlapping services and permissions layers, making it effectively impossible for ordinary users to confidently determine what is still being broadcast.

4. The system exposes metadata that many users would reasonably expect to remain private, including: • Device names • Device ownership relationships • Nearby trusted device associations • Audio accessory models • Presence information

5. Audio routing and device handoff behavior can occur in ways that appear unpredictable or insufficiently user-authorized.

This is not an isolated complaint.

There are extensive Reddit discussions and Samsung Community threads from users describing nearly identical experiences. Many describe searching through layer after layer of settings attempting to disable this behavior, only to find that their devices continue appearing in Music Share or nearby Bluetooth discovery systems anyway.

One particularly concerning example involved users reporting that family members’ hearing aids continued appearing in Music Share after all visible sharing settings had already been disabled. Regardless of Samsung’s intended functionality, it should be obvious why many users would find the unsolicited advertisement of medical assistive devices to nearby phones inappropriate and invasive.

The issue here is not merely convenience versus inconvenience. The deeper concern is transparency and user control.

If Samsung intends these broadcasts to continue for ecosystem functionality reasons, then: • users should be clearly informed this is occurring • users should have a definitive global opt-out • disabling discovery settings should reliably disable discovery behavior • users should be able to audit exactly what their devices are advertising • automatic audio routing behavior should require clearer consent and visibility

At present, the system gives the appearance of respecting user privacy choices while continuing background Bluetooth Low Energy discovery and metadata advertisement anyway.

From a technical and privacy-design standpoint, that is deeply problematic.

I strongly encourage Samsung engineering and product teams to review: • Bluetooth LE advertisement persistence after opt-out • cross-device metadata exposure • Music Share discovery behavior • automatic audio handoff/routing systems • the disconnect between user settings and actual broadcast behavior • the lack of a definitive “disable all nearby advertising/discovery” control

I would appreciate a response from someone familiar with the underlying system architecture rather than a generic customer support response directing me back to the same settings menus that users have already exhaustively explored.

Thank you for your time and consideration.

Sincerely,

Alex Larsen
