I discovered that nucleus smart (the companion app) is unnecesary to the objective to stream the audio of smartphone (including the call app) and phone after that i clicked to pair my hearing aids my phone immediately started to stream the audio and also the calls are perfectly working. On calyx with android 15 it was the same thing but calyx with android 16, iode and lineage (i don’t tried with nucleus smart uninstalled but when i will have time i will try) the call app doesn’t work
