I recently bought the Galaxy Buds, and changed the Bluetooth Codec in developer options. However, upon reconnecting them later, I noticed that they keep defaulting back to the Samsung Scalable codec. Is there any way to assign them a new default codec?
I've noticed this issue myself and while I can't offer an answer, I suspect there might be an issue with the BT system app. Have you raised this as an issue with Samsung?
I ended up calling a support line, but they just told me that that's how things are. I see this as a bug, because the official Galaxy buds specifications page on Samsung says that it can handle both scalable codec and AAC.
