I am currently using iqoo Z9 and brought realme air buds 6 that supports LHDC audio codec. But I currently came to know that no iqoo devices support that. Almost every phone brands has that. Kindly provide a update to provide support for that audio codec for all iqoo devices. Atleast, provide that update along with Funtouch OS 15. As you can see, there is no option for LHDC which means it is not supported by my phone.
