This happens to me randomly every once in awhile too. I get my notification sound with a peice of my ringtone thrown in with it. I also get sounds and ringtones randomly with no reason behind it. the phone will ring but there is no call or text. Happened 2 or 3 times so not a huge problem but it has to be the app doing it cause I never noticed it before I got Lightflow. It always happens when I am away from my phone so I have not actually been able to see what is on the screen when it happens. By the time I get to my phone or my girlfriend tells me it rang I unlock the screen to find nothing, no missed call or text.
I can try uninstalling and re-installing but haven't yet or maybe I missed a setting for an app that is alerting Lightflow but I don't have set to alert me on the phone itself or something?
I disabled the app all together and the double notifications and phantom notifications stopped! I'm probably going to keep it off until the app is patched.
Sucks... cause I really liked how this app allowed me to make the phone vibrate longer. I was no longer missing notifications when the phone was in my pocket.
