Latest Message<\/th>\nTitle: Users and admins may not receive new root detection alerts from the Android Microsoft Defender for Endpoint app<\/p>\n

User impact: Users and admins may not have received new root detection alerts from the Android Microsoft Defender for Endpoint app.<\/p>\n

More info: The Android Microsoft Defender for Endpoint app would no longer generate new root detection alerts during the rollback process. All other Android Microsoft Defender for Endpoint protections remained active and unaffected. Existing root detection alerts will not be removed and should be manually resolved if needed to avoid compliance or access issues.<\/p>\n

Final status: After further analysis, we’ve confirmed with affected users that impact was seen earlier than initially caught from our internal monitoring and we’ve updated the “Start time” field of this communication to reflect our updated understanding of the impact timeframe. We’ve completed our reversion of the affected root detection feature and confirmed with a subset of affected users that impact is remediated.<\/p>\n

Scope of impact: Users and admins expecting to receive new root detection alerts from the Android Microsoft Defender for Endpoint app may be impacted.<\/p>\n

Start time: Friday, December 19, 2025, at 9:38 AM UTC<\/p>\n

End time: Monday, March 02, 2026, at 2:10 PM UTC<\/p>\n

Root cause: The root detection feature on Android, which was in preview, had been identified to have inconsistent detection behavior and was resulting in impact.<\/p>\n

Next steps: We’re analyzing the offending root detection feature on Android to confirm why the inconsistent detection behavior wasn’t caught during our internal testing process prior to the feature being pushed to preview users. This analysis will help us to improve our testing processes moving forward to ensure similar impact scenarios don’t occur in the future.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
