Okay, GPS performance has degraded a lot over the last few days.

• Time to first fix is a couple of minutes now, instead of 5-30 seconds.
  
• Accuracy is reduced greatly, probably because the phone can one lock on to about 6-12 satellites, this used to be around 30 satellites.
  

In theory and under good conditions, you need 4 satellites to get a fix. But in reality, there are rarely “good conditions”, there are always buildings, hills, or trees nearby, so you need as many satellites as you can possibly get.

It’s not completely useless (yet), but it’s not great. I think I’m gonna lift some firewall restrictions. 🫤
