S25 ultra Bluetooth issues

[KylVie]

Hey since 31 of January I have s25 ultra.

So far I cannot complain about device until now.

Today I connected my Bluetooth ear buds,and sadly they keep disconnecting and reconnecting after around 15-20mins sometimes more often.

I have also noticed that my s25 ultra keeps removing my connected device in this case ear buds. 

Once I try to use them again I have to pair them again almost every single time I want to use them.

I tried what I could from reseting Bluetooth to even hard reset of the phone.

Just to add on other devices my ear buds works absolutely fine so It's not the buds issues.

Anyone with similar issues?

Not sure if this is software or hardware related issue.

I have also made a post about that, and is seems its not a prority for samsung to fix that, but hey, we received nicer charging animation ;D

I had same issue with my galaxy S25 Ultra. It connects fine for calls but not for other audio, like youtube. I went to connections> Bluetooth > Choose the earpiece or earbuds you have just connected > click on the screw icon( settings)beside the device and click audio. This should fix it.

Just wanted to provide an update… Ever since the June firmware update (US unlocked variant, fw build AYE3) the frequent Bluetooth disconnect and reconnect issue I was having with my Anker ear buds (an issue I did not have with these buds with my previous Galaxy device) seems to have been resolved. I have only experienced only one unintended disconnect since the update. Previously, over the same time span the ear buds would have disconnected dozens of times. Hopefully, this keeps up!

This morning 9/18/2025, my s25 ultra updated. One UI version 8.0, Android version 16, Kernel version 6.6.77-android15-8-31998796-abogki5938usqu5byi3-4k #1 wed sep 2 12:55:42 UTC 2025

After this update my bluetooth would not play music or make/receive calls with my car.

I deleted the old pairing record and tried to re-pair my phone to the car.  I get the message "Failed to connect"

It seems to me that something in this update has broken Bluetooth.

Thanks! This fixed my issue with one particular speaker constantly disconnecting and reconnecting.
