Yes, WiFi and everything else except for the afore mentioned sensors works fine. Occasionally the camera locks up while trying to save the image but that also seems to be a SW issue.
Meanwhile, I also have response from Fairphone Support and they also suggest doing a factory reset (without telling me where the questionable sensors are located… ). Nothing that I’m keen on doing but before spending a bunch of money on more spare parts, it’s definitely worth a try. It’s about time for some back-up and cleanup anyhow…
