</Update>

<Update label="May 2026" tags={["Mobile"]}>
  ## Developer Tools Detection - Available for iOS and Android

  Detect whether developer tools are active on a mobile device via the [Developer Tools Detection](https://docs.fingerprint.com/docs/smart-signals-reference#developer-tools-detection-for-mobile-devices) smart signal.

  * Helps identify environments where developer tools are active, which may indicate reverse engineering, dynamic instrumentation, or automated abuse when combined with other signals.
  * Requires [iOS SDK 2.12.0+](https://docs.fingerprint.com/docs/changelog-ios-sdk#december-2025) and [Android SDK 2.13.1+](https://docs.fingerprint.com/docs/changelog-android-sdk#february-2026).
  * Supported via [API v4](https://docs.fingerprint.com/reference/migrating-from-server-api-v3-to-v4) and API v3 responses.
