My wife has one of their lower end old models (A32) and it sometimes lags out playing Netflix. Everything is going fine, and then the video just stutters to the point that it's unwatchable. For comparison, that has a Geekbench score of 500 single threaded and 1650 multithreaded[1].
This is on top of other issues like the wifi just not connecting after a bit, or the bloatware and constant struggle fighting against their incessant notifications. After this, I'm never getting her a Samsung phone again. Please Google, don't kill the Pixel line... you're our only hope.
