A Bluetooth device only reports its own name through AudioDeviceInfo.productName while it is enumerated as an active output, i.e. while it is connected. Paired-but-switched-off devices therefore had no name to fall back on, and the platform-name cache is in-memory only by design (bt-device-identity ADR-4), so it self-heals per session ONLY for whatever happens to be connected. Every other device showed its raw id. Android already knows those names: BluetoothAdapter.getBondedDevices() lists every pairing with its name and MAC, connected or not, and nothing in this app was asking. Read it and seed the platform-name cache from it, keyed bt_a2dp:<uppercase MAC> to match the ids the audio layer emits. Seeded BEFORE the active-device query so a live enumeration name, being the fresher of the two, still wins; a user's custom name outranks both. Re-read on refrescarDispositivoActual so pairing or renaming a device in system settings shows up as soon as the list becomes visible. Reading the bond list is gated by BLUETOOTH_CONNECT from API 31 and by the legacy BLUETOOTH permission below it, so declare the latter with maxSdkVersion 30. It is a normal permission: granted at install, no runtime prompt, no new friction. When the answer is unavailable — permission denied, no adapter, Bluetooth off — both layers return an empty map rather than throwing, and the row degrades to the id exactly as before. Does not help rows persisted under a bt_a2dp:name: placeholder id: those never had a MAC to match against.
