there seems to be an issue with the edge lighting on the new android update with WhatsApp. What is happening is that every notification including the ones that do not turn on the display are activating the edge lightning. For example normal messages from muted groups now activate edge lightning. This never happend to me before the update. This only happens when the screen is turned off, it does not activate with the screen turned on. Is there anything to do except for turning off notifications / edge lighting?
First try to delete data and cache from Edge Screen in Applications menu then restart and reconfigure all edge system again as new, Try it if do not work correctly I suppose than an update will be come short fixing the engine
