Does anyone know how higher res codecs are implemented onto/into a handset? I was under the (mistaken) impression, that with the introduction of Oreo, the higher res aptx-HD and LDAC codecs are baked in to Android. That hasn't happened with my 2 year old Moto G5+ though. Even looking at gsmarena, they seem to suggest that a brand new $1500+ S10 only comes with aptx? Is it just luck of the draw with a phone? Apologies to Iphone/Apple users if they don't know what any of this is.
