They informed me over email they hope to have have VoLTE working in two to three weeks. I might pick one up. I know it’s not ideal, but currently no Linux phone is really a reliable daily driver if you also happen to want GPS, calls, texts and MMS, good performance, and good battery life. I’d be willing to settle with the FLX1 for now if I had to.

Maybe in time the OnePlus 6’s call audio issues will be sorted out and I can start using that as a daily driver again with working VoLTE this time thanks to 81voltd. Audio issues with it meant that I ended up giving up on it for now just today infact.
