I'm new to the samsung. I'm facing weird issue which is white missed call notification when using night mode. It appeared to be only when using dual sim and I have removed one sim from device and it resolved itself. It's just me or everyone using dual sim facility facing this on samsung one ui ??? I have reported to the samsung about this issue via Samsung members app but didn't get any response. I have attached some screenshots so yiu can get an idea about what I'm talking about
