I'd argue Google doesn't support them at all. They don't have repair centres, they don't sell parts - if I break a screen in my OnePlus, I can send it back to OnePlus and have it replaced with a genuine part for £79 last time I checked. With Google I know someone who cracked the screen in the Pixel 4 and Google's response to it was "well, sucks to be you, we don't repair any phones at all". That's shocking, and unacceptable for any hardware product.
