If you are experiencing difficulties activating Edge Lighting despite your efforts, this information may be beneficial. Shortly after acquiring my S24 Ultra, I downloaded the Good Lock application from the Galaxy store to enable the lightsaber sound effects when removing and inserting the S Pen. Additionally, I installed several other Good Lock applications to optimize the phone's capabilities, considering its advanced AI features. However, despite knowing the necessary settings, the Edge Lighting remained inoperable. Multiple attempts proved unsuccessful. Despite consulting various forums and instructional YouTube videos, the issue persisted, leading me to believe it was a software problem that required a future update. During this interim period, I explored additional options within the Good Lock application and discovered that I had downloaded and activated Edge Lighting from that source. Upon deleting this application, the desired Edge Lighting (glitter) became functional. This revelation identified the root cause of the problem. I hope this helps.
