Video calling through Signal is a no-go, right now, as it is lagging to no end. I don’t any other apps for it, so I don’t know if it’s the OS, app or the Fairphone 5. Anyone else had this issue?
Try to be in WiFi for video or even audio. I find on the cell towers it can be iffy as we changes towers or get in fringe range. If problem persists there is a Signal forum you could probably find the best information there.
Apologies for the late reply. I have it on to prioritise wifi calling. However, it seems to be working fine for the first ten minutes or so, so I don’t know if there’s some caching going on. The issue is non-existent on the Mac.
