Display / backlight issue after One UI 7 update

[userc8s5di8WeQ]

Ever since the latest UI update, there appears to be a display / backlight issue where the top left notification bar will flash white, and the backlight on the left side of the screen will increase with it. It started as short flashes, but now it lasts for several minutes. It happens in all applications and the home screen. I've restarted the phone multiple times and the problem persists.

This isn't a solution, just a workaround.

also called "Backlight Bleeding". I found a youtube video from 2023 with the same Display Smoothing fix. The issue only occurs infrequently on my phone, it has to be a software issue or the smoothness fix wouldnt work. its still a pretty strange problem since it only started sometime after my last system update July 1, 2025
