Action required: Update Microsoft Defender for Endpoint Android App

What and Why

To support upcoming Microsoft Defender infrastructure changes, organizations must ensure devices are updated to Microsoft Defender for Endpoint for Android version 1.0.9107.0101 or later. Devices running older app versions may experience disruption to mobile threat protection capabilities after the infrastructure update, and administrators should communicate the update requirement to affected users.

Rollout Schedule

Worldwide, GCC, GCC-High, DoD: We will begin rolling out on early August 2026 and expect to complete by mid-September 2026.

Impact on your organization

As part of an infrastructure update expected by mid-September 2026, devices running older versions of the Microsoft Defender for Endpoint Android app may experience disruption to mobile threat protection capabilities if they are not updated to a supported version.

Action Required/Recommendations

To avoid potential service disruption following the infrastructure update, administrators should:

• Verify that managed devices are running a supported version of Microsoft Defender for Endpoint.
• Update devices running older app versions to the latest available release:
• Android: Version 1.0.9107.0101 or later
• Communicate this requirement to users who manage application updates themselves.

No additional configuration changes are required. Updating to a supported version of Microsoft Defender for Endpoint is sufficient to maintain access to protection capabilities following the infrastructure update.
