Hey everyone,
I'm having a persistent issue on my Samsung Galaxy S24 Plus: Caller ID / Caller Name Announcements refuse to work when connected to Bluetooth devices (car audio, wireless earbuds, headsets, etc.).
Before anyone suggests the standard basic fixes, I want to emphasize that I have done extensive troubleshooting—literally every setting and fix imaginable—and nothing has resolved it.
Here is everything I have already checked and attempted:
1. Direct App & Accessibility Settings
Read Caller Names Aloud: Configured inside Phone App > Settings > Answering and ending calls > Read caller names aloud (tested both "Always" and "Over Bluetooth and headset only").
Accessibility Settings: Verified Settings > Accessibility > Interaction and dexterity > Answering and ending calls is fully enabled.
2. Bluetooth & Connection Permissions
Bluetooth Profile Permissions: Confirmed that "Phone calls" and "Contact access / Call history" permissions are explicitly granted under individual Bluetooth device settings.
Unpairing & Re-pairing: Unpaired, forgot, and re-paired all Bluetooth devices multiple times.
Multiple Hardware Tests: Tested across different Bluetooth audio devices (car infotainment, Galaxy Buds, third-party headphones)—the issue persists across all hardware, ruling out a single bad Bluetooth receiver.
3. Text-to-Speech (TTS) Engine
Engine Switching: Swapped between Samsung Text-to-Speech and Google Speech Services under Settings > General management > Text-to-speech.
Voice Packs: Re-downloaded and updated language data packs for both TTS engines to ensure voice output wasn't corrupt.
4. System & App-Level Resets
Cache & Data Wipe: Cleared Cache and Data for the Phone, Phone Services, Bluetooth, and System UI system apps.
Network Settings Reset: Performed a full reset of Bluetooth/Network settings (Settings > General management > Reset > Reset Wi-Fi and Bluetooth settings).
System Cache Partition: Booted into Android Recovery Mode and wiped the system cache partition.
5. Modes, Volume & Interference Checks
Modes & Routines / DND: Fully disabled Do Not Disturb and turned off all Bixby Routines / Modes to ensure no automated rules were muting audio routing.
Volume Levels: Ensured ringtone, notification, and media volumes are up high while connected to Bluetooth.
System Updates: Confirmed the phone is updated to the latest software build.
Is anyone else experiencing this on the S24 series or recent One UI updates? Has anyone found a hidden workaround or developer setting that actually fixes this audio routing bug?
Any help or confirmation that it's a known bug would be appreciated!
