Light Flow is the type of app that is distinctively Android. It's both basic and complex at the same time, choosing a single aspect of your phone to mess around with (in this case, its notification LED) and providing a bunch of options for doing so. The latest update brings along a bunch of features, but it's particularly interesting if you own a Sony smartwatch or Xperia phone with an illumination bar.


Sony device owners don't get all the fun though. Light Flow will now send better text notifications to dashclock and Pebble smartwatches running Android 4.3 or higher. Vibrating while in a call should also work on more phones. You can get the full changelog here.

What's new (lite):

  • Sony smartwatch support
  • Sony illumination bar support
  • Memory improvements
  • LG2 back button led control
  • Fixes for SMS and hangouts
  • Better text to dashclock, pebble, smartwatch on android 4.3
  • Vibrate while in call working on more phones

What's new (pro):

  • Fix for hanging on some sony phones
  • Changed default settings for Xperia illumination bar phones
  • Reworked switch screen on option to prevent delay
  • Better text to dashclock, pebble, smartwatch on android 4.3
  • Vibrate while in call working on more phones
  • Option for simpler text in lightflow persistent notification just listing the number of notification types on
  • Bug fixes
  • Many more changes

    It doesn't work reliably with the Nexus 5

      I have a Nexus 5 and have no issues with it at all

        Same, no problems here, stock or custom.

        For notifications I've modified using light flow, only show up as a pale multi-colour that's almost white. I'm on stock with Franco Kernel. Maybe i'm doing it wrong...

      If you held down the persistent notification and then went to app info and hid the notification the entire program wont work. That seems to be a common issue ppl have. It works fine on my nexus without the run in foreground option.

        You should not be using the run in foreground option anyway.

      I've had problems on the Nexus 5 as well, so you're not the only one.

    Don't seem to get the update yet. Can't wait to try it out on my Xperia S!

    I always found this one buggy and have had much better luck with light manager.
