Google keeps locking tons of Android features away behind their own privatized software stack.
Better for Google, but they are cutting their nose to spite their face here, as Android as a whole suffers for it.
Stuff like call screening in the android dialer would be possible on any brand of device. But no, pixel only.
The pixels have the very best android experience. It comes close to iPhone. But pixels aren't the whole market. Overall Google is trying to claw back control of the entire platform and I hate it.
