September 2025

Smart Signals

v2.10.0

What’s new

• Introduced a new proximity detection location-based signal for mobile devices. Instead of representing a unique device, the new proximity ID corresponds to a fixed geographical zone within which the device is observed. This additional layer of context makes it possible to identify groups of devices in the same physical area or a single device that may have changed its identity but remained in the same location. See Proximity detection for Android devices reference for more info.
  • The Android SDK will only collect location data if the new allowUseOfLocationData option is set to true.
  • It’s possible to configure the location retrieval timeout by setting the new locationTimeoutMillis option to a desired value. By default, it’s set to 5 seconds. Refer to Using Location Data for Proximity Detection page for configuration details.
• Enhanced the detection logic to more accurately identify true factory resets on Android devices. This update reduces false positives and improves signal reliability for fraud prevention workflows.

Compatibility

• Requires Android 5.0+ (API Level 21 or higher)
• Tested with API Level 35 (targetSdk = 35)
• Compiled using API Level 35 (compileSdk = 35)
