Some info on Huawei HWA/LHDC phones
Obviously, the high end P series and Mate series is supported, selected models only. Below are the cheaper Nova series models
Nova 4
Nova 4e
Nova 3
Nova 3i (cheapest, best value)
Huawei P Smart+ Plus (Europe' Nova 3i)
Note the official Huawei consumer site on some countries may NOT list HWA/LHDC is supported but it is for these models. I crossed referenced the models to China site. Higher end P & Mate models support *both* HWA/LHDC and Sony LDAC.
Eyeing the Nova 3i now, small battery 3340mAh but taobao is selling a charging case with 20000mAh battery built-in. Just slip on and charge like a power bank, as you use normally.
How am I going to live without root Magisk on this phone? Maybe someone can make a magisk module with HWA/LHDC, all Android phones can use the BT codec. Maybe people should ask for this at XDA or 4pda.ru
EDIT: TaiChi framework can load some xposed modules in non-root mode
Right now the Fiio music app can emulate HWA/LHDC on any phone (leave it running in background) but it's not stable.
EDIT: mini
review of Mate 20 Pro and Huawei Freebuds/Flybuds2, both support HWA/LHDC
