I previously reported an issue after updating to One UI 7. My S23 developed a strange, thick, radio static-like bar or line near the top of the screen, just below the camera. Giving Samsung the benefit of the doubt, I initially thought it might be an isolated issue with my unit. However, upon updating my second S23, it exhibited the exact same problem.
This line is transient, appearing for only about 5-6 seconds before disappearing. I've also observed that it seems to occur more frequently when battery saver mode is enabled.
