I have 3 xz1cs in the house, my wife's (running stock) and two of mine (running custom). Two have flawless GPS under any ROM. A third one has finicky GPS also irrespective of ROM, custom or stock. It sometimes loses signal and more generally locks in with some delay.Some Sony g8441 devices have GPS issues of unknown origin. I've watched logs and tinkered around a lot, actually for over a year now, but I could not find any clue. The XZ1C of a friend, on the other hand, has perfectly working GPS running exactly the same LineageOS builds and software as I do.
This applied to at least LineageOS version 16, 17.1 ans 18.1. So I'm pretty sure it has nothing to do with the operating system, it rather might be a hardware issue. Maybe some g8441 just have faulty GPS receivers.
