The MDM auto-detect added in #166 asked "is any device admin active outside our package". On a stock Fire TV stick the answer is yes: com.amazon.tv.parentalcontrols is registered, holding wipe-data and nothing else. A retail stick with no enrolment anywhere therefore declared itself MDM-managed and opted out of updates for good — one sat 12 versions behind (1.9.11 against 1.9.23) while the server offered it every release in between. Device admin is not device owner. isDeviceOwnerApp/isProfileOwnerApp are public since API 21 and accept any package name, so the owner really can be read directly; the comment claiming otherwise was the root of the over-broad test. Profile owner is not enough either — on that same stick parental controls owns user 0 — so the check is now a foreign DEVICE owner, and delegated install scope short-circuits it since an owner that delegated installs to us wants us installing. Where doubt remains the asymmetry decides it: standing down wrongly is silent and permanent, while attempting wrongly is capped at MAX_INSTALL_ATTEMPTS and surfaces manual_update_required. Better to be the kind of wrong that reaches a dashboard. That visibility was missing too. The stand-down ran before the version check, so a managed panel never learned an update existed and kept reporting ota_status 'none' — indistinguishable from up to date, which is why nothing flagged it. It now checks first and parks genuinely-managed panels in manual_update_required, announced once per target version rather than every polling cycle. ManagedLogic is a pure seam alongside TierLogic; the admin shapes under test are the ones dumped from the real device. |
