Android Requirements

Requires Android 4.3 or better, and Bluetooth 4.0 support on the phone. We have seen better BLE stability with Android 4.4 and Google Nexus devices. We have tested with Nexus 5, Samsung Galaxy S4, Note 3, and Note Pro (tablet). Older phones have been less stable, especially for firmware updates.
