Bugs I have encountered with a fully updated Nokia 5 on Pie, as of 13 march 2019:
-Mobile data dies completely occasionally, and can only be reinstated by rebooting the phone. I am not sure, but this seems to be related to the power save mode kicking in, so I stopped using it.
-Wi-fi module "sees" and tries to connect to networks that are registrered in the phone but out of range, leaving it with no Wi-Fi connection as it will stay for a while and try to connect to a network that does not really exist in range. The connection attempts end with "Authentication problem." This one is VERY weird. It can be mentioned that the locations where I see this "confusion" happening have WiFi routers of the same brand and model, but indeed, different MACs and SSIDs on the respective sites and if the phone misidentifies WiFi nodes because they are of the same brand and model something is seriously wrong!
-Camera refocuses periodically when filming, so the end result is much jumpier than need be. Solution - let the user focus-on-request by tapping screen. My previous budget Samsung model had it this way, much better result.
-Disconnecting wifi gives a warning message saying that the wifi connection has no internet. Absolutely not a biggie, a bug nonetheless.
Anyone else seeing those? I am especially concerned about the mobile data/wifi bugs as they seriously hamper usability of the phone.
