If you enable developer settings by tapping the version number in, about settings 5-7 times you can enable "show refresh rate" and see how it changes in real time.

I use Lawnchair. The animations are okay. The same imperfect animations as on my Pixel.

Good to know.

E: Actually I think the back animation is a bit more broken for some apps.

I guess some things can be broken more or less. Thanks for the response.

Consider doing a longterm review in the future when use the phone for longer than a few months.
