You probably already know this, but you can change various Bluetooth audio-related settings like the codec, sample rate, and more by going to Settings > System > Developer options.
You shouldn’t have to use this menu as your Android device and headphones should negotiate the best settings, but sometimes, they just don’t. For example, every time we connect my WH-1000XM3s to the Nothing Phone 2, it defaults to aptX HD even though we enabled LDAC on the headphones through Sony’s app. But there’s a bug in Nothing OS 2.0 that prevents you from changing the Bluetooth codec in Settings (all the options are blank)!
But thanks to this app, called Bluetooth Codec Changer, we can change the codec to LDAC! The app also has a long list of extra features, available through a one-time in-app purchase (currently $2.99, normally $9.99), such as automatic codec switching, profile saving, widgets to change profiles, and more.
(Thanks to aborne25 for bringing this app to my attention! I should’ve mentioned this in my other post on Cast Receiver, but neither this thread nor that one was “sponsored” in any way, and I’m not in contact with the developers of either app.)
