There doesn't seem to be any conclusive information regarding aptx support,
A chap here said Nokia support said it's not supported,
Is this true?
Bluetooth checker says it does,
but I don't really trust that site.
It do support aptx hd in theory , but in practice Oreo update 8.1 have messed up Bluetooth so much that i for one can not get aptx (and many other Bluetooth functions) work like they should.
I suspect this is because of google trying to implement the AAC codec. My car stereo do not work unless i manually change the codec to SBC and then i loose aptx.
Really this is ridiculous, a phone in 2018 not properly supporting aptX, loads of people are moving to wireless headphones now what with a lot of phone manufacturers dropping the headphone jack and the majority of wireless headphones out there are aptX codec supported, why on earth is Nokia turning a blind eye to this?
As stated above, the problems is most likely caused by google and the 8.1 update. (and is present in the pixel series )
I agree that Nokia should push on google to fix this asap or open all 7+ to the beta channel for updates (or a possible downgrade to 8.0).
