I've had Light Flow for 2 months with no issues. Was able to set up different colors for different notifications and have the phone vibrate when a text message or email came in. For the last few days, the lights still work, but I no longer can get the phone to vibrate when an email or text message comes in. I think I have checked all the right settings both on Light Flow and the Nexus settings screen. Tried uninstalling and reinstalling Light Flow. Per someone else's advice, I also downloaded another app called Sound Manager V2, and checked "vibrate whenever possible" for both ringtones and notifications. Still no luck. Is anyone else having this problem and does anybody have a fix? Thanks in advance.
