I don't think the Indian government realistically has the ability to enforce on Apple/Google/Samsung like that. Regardless, even if they did, India has a diversity of (what we would probably consider) garbage smartphones. For anyone who lives in the West and is used to the kind of state legibility and control here, I think they'd find India quite surprising. The state has limited visibility and control there, simply because they never built a trustable bureaucratic network of data transmission.

If you read the Internet, you will hear that India has strict controls on KYC for SIM cards and so on. But on my last trip there I acquired one without much fuss. I'm not sure how that happened but I didn't provide any ID! I suspect that in such an environment you can't really do the thing you're suggesting.

The average mobile phone store there had an absolutely mind-blowing profusion of smartphone brands that all sound like those Amazon drop-shipped Chinese brands: Vivo, Poco, Realme, Oppo. And those are the good ones! There is a Cambrian-like explosion of brands there from various manufacturers. It's an unusual place.

EDIT: I'm going to have to reply to you here because I'm rate-limited on comments. See below in response.

Is it contradictory? I imagine saying "install this app on your phones from the factory when selling here" is a lot more achievable than coordinating what you suggested which is:

> ...build tools, reporting, support services around helping with both Scamming applications or Stolen phones etc....

But perhaps you anticipate these to both require equivalent ability? If so, I think that's the crux of the disagreement. I don't think the Indian state has the power to set up a mechanism to set a standard for tools, reporting, and support services that meet some requirements to detect scammers etc.

In fact, I think that's a really high bar. I think perhaps only highly developed nations would have any success designing such a program. I think even the smaller EU member nations would fail at it, and I don't think any of the developing nations (barring China).
