This version of Light Flow is for Android 6.0 users who do not wish to have a persistent notification icon.
It has the same features as the standard version of Light Flow minus the following:
- Android 6.0 Run-time permissions
- Camera flash control
- Alarm only mode notification
If you have the standard full version installed this app will give you the features of the full version.
If you don't have the full version installed, it will give you the features of the lite version.
See the reason for the existence of this version here: http://www.reactle.com/2015/11/android-6-persistent-notification-icon.html
If after disabling the full version you still have a persistent notification try going into your phone settings, apps, select "light flow" (ie not light flow legacy) and press "force stop"
