I have a Samsung S20 ultra. I loved my edge lighting! What happened to it? It is now an app you have to pay $2.50 for! This is BS. I want my notification edge lighting back. I paid over $1300.00 for this phone, I think I already paid to have it stay.
So edge lighting was moved. It is under notifications. Set to brief. Tap on brief pop-up settings. You should see edge lighting style there.
Edge lighting has barely worked for me since day 1 of getting the s20 ultra. I have every app selected to use it but only 2 or 3 actually do. That was one of the things I was looking forward to in the phone too.
