Do you know the smart notifications in LED Blinker yet?
You can use smart notifications to assign different colors to specific WhatsApp groups or to add contact specific LED notifications for missed calls or sms.
Just choose the app, e.g. WhatsApp or dialer app, and enter the group name or contact’s name for the text, which has to be part of the notification (in the red area written).
Afterwards you just have to configure color, vibration and sound – like you do with each normal notification.
