Due to Google’s proprietary algorithm, we cannot predict exactly who will get the message and who will not. Nearby Notifications will be received by most nearby Android devices, some on the lock screen, and some in the notifications folders.
Requirements for receiving Nearby Notifications include:
- Device is running Android 4.4 or newer
- Bluetooth and Location services are enabled
- Nearby notifications have not been actively disabled on the device
- The Nearby message and URL abide by Google's Nearby Notification content policy
