Hello,
the Galaxy SmartTag 2 is only compatible with Galaxy Smartphones and Galaxy Tablets with Android 9.0 and higher and 3 GB RAM. The SmartThings app is required for use. The Bluetooth range is up to 120 metres. You can also locate objects beyond the standard Bluetooth range (up to 120 m). Together with the SmartThingsFind network, you can extend the range.
