This sounds like cool trick for all Lumia Selfie lovers!! In case you own a Treasure Tag, you can use it as a remote shutter to take Selfies on your Lumia device. What you need to do is to install the latest “Lumia Selfie app” on your devices. This is how it works,
Once you’ve installed or updated the Lumia Selfie app, simply open the app and the app will automatically detect if a connected Treasure Tag is in range (using BT LE). A press of a button on the tag will then trigger the camera on your Lumia.
