Hello Nokia, Since I have bought Nokia 5, I have seen two major upgrades to it, 8.0 and 8.1. But unfortunately none of them fixed GPS accuracy issue. Nokia 8 was also having the same issue which was fixed through 8.1 upgrade. I have also written this in Nokia Support Chat app but they respond like a robot. Currently GPS accuracy is very much unreliable in Nokia 5. I hardly get accuracy below 10m even on the open area like roof. Please fix this issue. I cannot recommend anyone for Nokia if this issue is not fixed soon.
10m accuracy is perfectly reasonable and basically good for a phone's GPS. Reliably achieving 1m accuracy needs a higher spec GPS device and augmented / differential GPS, as normal civilian GPS can't reliably achieve that. If you are normally getting roughly 10-20m accuracy (when you have an unobstructed view of the sky in all directions), then it's working fine.
