Good  but... I used this on my Samsung S4 with ICS  and it worked good. Upgraded to Note 5 running Lolipop 5.1.1 and was woke up last night to the sound of a notification  vibration and LED from Facebook. Why? I had notifications  vibration and system sounds all set to off. Also  this app lacks the ability to disable or turn off the LED.
