I picked up a white 32gb s6 edge in my local Verizon store on Friday, and all was well. Today I noticed that the Edge Lighting feature no longer works. It's enabled in my settings and worked when I first obtained the phone. I tried restarting it to no avail. When I receive messages my screen lights up and shows the lock screen instead of showing the coordinated colours. This only happens when the screen is face down though, and the screen stays locked when it's face up and I receive a text. I tried turning the phone off and back on and switched the edge features from the right side to the left side and the first time I received a text the screen flashed on for a moment and then locked again and the edge lighting was turned on. It did not work after that, however, and I switch the features back to the right side. The screen no longer lights up when I receive a text when my phone is face down, and the lighting feature is still not working. Is there anything I can do?
