Moderators have got update on APTX and seems no timeframe for Adaptive APTX at present, but specialists state that Samsung Scaleable is very similar.
At the moment S10 and S20 series support traditional aptX. What it does offer, however, is Samsung Scalable. That is closely similar to Adaptive AptX, but has a wider range of bitrates. Samsung Scalable can scale to any bitrate between 88kbps to 512kbps, and should be always using the bitrate that provides best quality audio while maintaining a stable connection. Adaptive AptX only scales between 279 to 420kbps."
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
My Device- S21 Ultra 5G ( SM-998B/DS ) CSC= BTU , 12GB/256GB One Ui 5.0,Android 13 .
Samsung scalable is not a substitute as it only works with samsung headphones. We need apt x adaptive.. even my oneplus has it. It is awful that this feature isnt present on what is supposed to be a flagship device. Has there been an update since?
