2. Productivity

Auto launch Wynk and start playing last played song either by inserting headset or a Bluetooth audio. After the song is played, you can use proximity sensors to control play/pause, next, and previous.
All you have to do is hover near the sensor to play/pause, block the sensor for more than 3 secs for next, and finally, hover slowly for previous.
You can change wynk player to any other by selecting the appropriate receivers. If you are unable to find your receivers please comment your querry and let me help you.
