Pixel 9 user here since around two years. Always installed updates on day 1 and never had any of the issues promptly reported on reddit and news sites the day after the release. Since I'm not a particularly lucky individual, I think these kind of issues are quite normal (sadly) after a major software update and do not affect everyone. I want it to state it out because I was worried too when I first bought the device, but I do not think Google has a particularly worse QC than other brands. Other non Google devices have them too, iphones included. Pixel phones maybe get a bit more attention (as it should be, dont get me wrong). That said, I do hope it gets better and this issues not come again next wave of updates.
