S25 ultra Bluetooth issue

Ankit1102 — Tue, 08 Apr 2025 19:36:33 GMT

Since last 5-6 days, whenever I try to connect my buds 3 Pro to my Samsung s25 ultra, it connects properly but there is no sound coming from the apps like YouTube or Instagram. I even tried with different earbuds and the same issue persist with every buds. If I restart my phone it works perfectly for sometime and then the same issue occurs again. I went to the service centre for this and they first did a network reset, then they clear the app cache and a reset again, and finally they told me to do a factory reset of my phone which I did ( it was such a hassle ). And after all this the problem is still there, really frustrated and really pissed at Samsung.

Make sure you turn on audio permission for the Bluetooth headphones being used.

It sounds like you’ve been through a major hassle with your Samsung Galaxy S25 Ultra and Buds 3 Pro connectivity issues—only for the problem to persist even after a factory reset. That’s beyond frustrating, especially when service center steps didn’t fix it.

Possible Causes & Fixes to Try

Since restarting temporarily fixes it, but the issue returns, this suggests a software/OS-level conflict rather than hardware failure. Here’s what could be happening:

1. Bluetooth Stack Corruption

The Bluetooth driver or system process may be crashing silently.
Fix:
- Go to Settings > Apps > Show system apps (⋮ menu) > Search for "Bluetooth" > Force Stop + Clear Cache + Clear Data.
- Then, restart your phone and reconnect the buds.

2. Samsung Sound Assistant / Audio Relays

Samsung’s audio routing (especially with Dolby Atmos, 360 Audio, or Labs features) can sometimes glitch.
Fix:
- Go to Settings > Sounds and vibration > Sound quality and effects > Turn off Dolby Atmos temporarily.
- Disable "Separate app sound" (if enabled).
- Try disabling "Samsung Sound Assistant" (if installed).

3. App-Specific Audio Routing Bug

Some apps (like YouTube, Instagram) may lose audio focus due to a One UI bug.
Fix:
- Go to Settings > Apps > [YouTube/Instagram] > Battery > Unrestricted (prevents audio cuts).
- In Developer Options (enable if hidden), check "Disable absolute volume" and toggle it.

4. Firmware Mismatch (Buds 3 Pro)

If the buds’ firmware is outdated or conflicts with One UI 6.1/7.0, audio may drop.
Fix:
- Open Galaxy Wearable app > Earbuds settings > Update firmware.
- If no update, try resetting the buds (forget device + re-pair).

5. Deep System Reset (Beyond Factory Reset)

If factory reset didn’t help, the issue might be tied to firmware partitions.
Nuclear Option:
- Flash stock firmware via Odin (download latest S25 Ultra firmware from Frija/SamFirm).
- Or, visit a different service center and demand board-level diagnostics.

6. Temporary Workaround

When audio stops, try toggling Bluetooth off/on or switching audio codecs (AAC/SBC in Developer Options).

Thank you for the detailed solution! I did try few things. I don't know what worked but from the last couple of days the issue has not come up again. Touchwood.
