aptx on W10/ W10mobile - Microsoft Community

i read microsoft community, , found windows 10 , w10mobile has no doubt support bluetooth aptx codec. https://msdn.microsoft.com/en-us/windows/hardware/commercialize/design/component-guidelines/bluetooth?f=255&mspperror=-2147217396

i try success on w10 pc aptx enabled dongle, sound really good , no delay during video playback.

however, different story on phone.

- sound quality is less rich when comparing same song same headset on aptx enabled pc , on phone

- 1 of aptx feature low latency not showing when play video on lumia 930 , lumia 1520, ie, sound delay when playing video.

another point is, aptx should licensed csr work. hardware embedded. csr shows device list which obtained aptx license, find lumia 630 in website.

it makes me suspect whether aptx working on lumia phone?

wish microsoft can clarify. thank you.
