Lumia Selfie app was today updated in Windows Phone Store to v184.108.40.206. This update added the ability to use a Treasure Tag as a remote shutter. And all the photos are saved automatically when you take them.
Lumia Selfie app is specifically designed for taking self portraits with your front or main camera and sharing them with your friends. It’s easy to capture the perfect picture of yourself, automatically enhanced and ready to share. You can also fine-tune your selfie’s appearance and apply high quality effects. The remote shutter feature requires the Lumia Cyan software update or later. Remote shutter works best when you have the Treasure Tag app version 1.7 or later installed.
