One UI 6 Update: poor audio quality on Bluetooth earplugs

(Topic created on: 11-12-2023 06:40 PM)

After updating to One UI 6 (A54), my earplugs connect fine, but audio is really poor. I can even listen it how bad it is.

I did all the basic/obvious troubleshooting, with no luck (forgetting the connection and redoing it, restart connections, restart the phone..)

How to fix it?

EDIT: Seems that this is frequently appeared error. Samsung could fix it but we need to report it.  It is really easy to do it via Members app:

This worked for my A54 ... hope it works for you ....
I think I have found a temporary fix (I have a A54)! You need developer options enabled.
Scroll down to "Turn off A2DP hardware offload" and toggle this setting ON. Since adjusting this my bluetooth headphones are no longer making distorted sounds and are working perfectly.

From what I have read online the A2DP hardware offload is related to either the phone or headphones decoding the audio. If toggled OFF (as it was when I first checked after the One UO 6.0 update) then it is expecting the headphones to decode which most can't (hense the distortion) but if you turn it ON then the phone will decode the audio.
Thank you! Been annoying me for ages whenever I interact with my phone (UK 22 ultra) in the last few months. That worked for me.

I'm sorry to hear about your disappointing experience. It sounds like you've encountered several issues with your amplifier. Here are some suggestions on how to proceed:


  1. Check the Components: Even if the components look intact, there could be internal damage that isn't visible. Use a multimeter to check the continuity and resistance of each component.


  1. Repair Burnt Traces: For the burnt traces, you can use a copper wire to bypass the damaged trace. Scrape off the protective coating on the damaged track until you expose intact copper, then solder the copper wire to restore the connection.


  1. Replace Ground Cables: If the speaker ground cables are damaged, replace them with new ones. Ensure they are properly connected to the board and free of short circuits.


  1. Inspect the Power Toroid: The yellowish-black mark around the power toroid pins suggests an overheating issue. Ensure the pins are properly soldered and there are no short circuits.


  1. Check the BDG400: Use a multimeter to check if the BDG400 is short-circuited. If it is damaged, replace it with a new one.


If you still encounter issues after these steps, it might be helpful to consult a specialist or consider professional repair services.
