The pixel 2 was my 4th android, and I honestly hadn't experienced anything quite like the performance issues on the pixel 2 in the last 2 years.
Look, it might very well be a shitty phone. Just saying that after 4 years I'd cut any phone a break. Especially since phones got impractically thin, batteries have really struggled to work the way they do when they are new after a year or two.
I still miss the hardware keyboard.
