DeletedUser495 I would like to see such evidence from you.
Presumably you mean counter-evidence? But that doesn't make sense. I did not claim that Google does not track OEM unlocks.
A poster claimed Google does track OEM unlocks. I explained why that is both unnecessary and unlikely, at which point I think the burden of proof would be on the person making the claim.
To be clear: I don't know whether Google does or doesn't track OEM unlocks. I doubt they do, because they don't need to do that for their unlock system to work, and because (as at least two people have pointed out) every device does an unlock check when it first gets Internet access, at which point it has no idea whether the user will or won't ever OEM unlock, and because the actual unlocking step (which, again, can be done hours or days or months after the check) does not require Internet access.
But I am not claiming they do, and I'm not claiming they don't. So I think somebody who wrote "They track literally every device, where it has been sold, if its part of a carrier deal or part of an enterprise deal. And its current unlock status" (DeletedUser481, emphasis added) should provide "literal" evidence.
The key issue is that every device "phones home" to find out whether it can be OEM unlocked (or at least every device sold in certain countries). If every device "phones home" to find its unlock status, how is Google tracking which devices are actually OEM unlocked?
