Many users have said that their phones are buggy, and unfortunately, mine is too. I updated my Nokia 5.1 to pie using the India VPN trick (pie isn't available in the United Kingdom yet) and it's absolutely horrible. I had to reset my fingerprints, because it didn't remember any of them, there is a battery drain, and some things don't work. Also, there are many evenwell packages that you will want to uninstall. Pie is not polished yet, and I'm very angry that HMD allowed this to go througu without fixing a the bugs.
