I think I'm right in saying the Note 3 has low energy Bluetooth 4 - not much available on Android devices (is that right)? The reason I'm interested at the moment is the "lost items" tile device and App being developed... Tile app The developers say "Q. No Android support? "A. At this time Android does not support Bluetooth 4.0. A few Android phone manufacturers have released BLE SDKs, however they are lacking in quality and stability. At Tile, the quality of our products is of utmost importance, and until there exists an Android platform that meets our quality standards, we will not be releasing a Tile app for Android."
