Play Protect Blocking Custom DPC Apps — How to Get Approval or Alternatives?

Hi everyone,

I'm a developer who helps enterprises build custom DPC (Device Policy Controller) Reference Documentation apps to manage Android devices based on their unique requirements.

Recently, Play Protect has started blocking the installation of custom DPC apps, even when these apps are signed and used internally. The warning claims the app may pose a risk due to access to sensitive data - even though it's strictly for enterprise use.

To make things more difficult:

• Google is no longer accepting registration of custom DPC apps with Android Enterprise, which limits official distribution and management options.
• Android Management APIs don’t support all use cases, and also have quote limit.
• I’ve applied twice to join the Android Enterprise portal to build a SaaS-based device management platform, but both requests were rejected without a clear reason.

My questions for the community:

• Is there any official way to get a custom DPC app approved or whitelisted by Play Protect?
• Are there any alternative ways to manage Android devices at scale (outside of AMAPI or legacy EMM)?
• How can new developers or startups gain access to Android Enterprise features when onboarding is currently restricted?

Any help, direction, or shared experience would be greatly appreciated.

Thanks,

Kulwinder
