Bluetooth audio quality is bad after update S24 Ultra

[sushi_ridhs]

After the recent update, I've noticed that my S24 ultras bluetooth audio quality is bad (sounds dull and muted). I have multiple bluetooth headsets and speakers. The first device connected after restarting sounds normal. Every other device sounds muted and dull. I need to restart my phone if I want to play music in a different device to have better sound quality.

Has anyone experience this?

The solution is turning off Dolby Atmos 👍🏻

My M31 bluetooth music is better than my S24.

Yes, I  believe this is the fix as it definitely did for me.  I run Pandora via Bluetooth to my Denon AVR x4800h along with a substantial investment in a 7.1 theater system and highly value my waves. After the android 15 upgrade on my Galaxy S24 Ultra, the output was a disaster.  I called Samsung and they said they're aware of the problem and currently working on a patch. However,  someone who must be a God of music, posted these below instructions.  I skipped to the, reset bluetooth and wifi settings, cleared Pandora's cache. Unpaired my phone from the Denon. Turned off the phone for 3 minutes, powered everything back on,  reestablished wifi settings and then re-paired my devices and I'll be damned, my ears are back to doing the soft-shoe. Hope this works for you and if it does,  please repost it. 

If your Bluetooth is malfunctioning after upgrading to Android 15, try restarting both your phone and the Bluetooth device. If the issue persists, you might need to reset your phone's Bluetooth and Wi-Fi settings in Settings > System > Reset options > Reset Bluetooth & Wi-Fi. Some users have also found success by using the repair mode to fix Bluetooth issues.

Detailed Troubleshooting Steps:

1. 1. Restart:

   Restart both your phone and the Bluetooth device (headphones, car, etc.) to refresh their connections. 
2. 2. Reset Bluetooth & Wi-Fi:

   • Open the Settings app. 
   • Go to System. 
   • Select Reset options. 
   • Tap Reset Bluetooth & Wi-Fi. 
   • Confirm the reset. 
3. 3. Repair Mode:

Also, turn off, if you turned on the Dolby Atmos in your phone settings because it degrades the sound on your Bluetooth device.

After the update when I try to make a call the Bluetooth disconnects from my car stereo reconnects then disconnects seconds later. I didn't have any issues before update. Bluetooth audio to same stereo works fine for music and movies
