It is too bad it was a private conversation, I would love to be able to point to a published form, but I discussed with one of the Googlers in charge of optimizing Android. He did not exactly have nice things to say about how OEMs are optimizing their phones. Basically they optimize in order to get higher benchmark score but it very often goes against general smoothness. In the end he published a detailed article detailing how his team had optimized the pixel phone rendering pipeline so OEMs could try to do it correctly as well. And that's for a high end phone. However, I have got to say that after using iOS phones recently, I have not exactly been impressed with their smoothness either. Even system apps miss frames. That's not shocking in itself, mobile computing is pretty hard, you can't even table on a stable cpu frequency (thermal throttle) but not what I expected due to the reputation of apple phones.
