Text message handling with DashClock, Pebble and Hangouts also improved
One of the most popular notification, vibration and LED control apps, Light Flow, has just been updated to improve compatibility across multiple devices and apps. The biggest of the bunch will be Sony SmartWatch 2 support, along with the notification LED on the back of the LG G2 and Sony phones that came with an "illumination bar" down at the bottom.
The update also improves text message handling when you have DashClock installed or a Pebble connected when running Android 4.3, as well as genreal fixes for SMS and Hangouts. These updates are all included in the free version of Light Flow, which you can download from the Play Store link above.
