Issue After ONE UI 7 Update on Galaxy S23 – Screen Flicker on Lock Screen

[Ameenhuzain]

Hi everyone,

I updated my Samsung Galaxy S23 to One UI 7 on May 1st. During the update, I ensured the phone was cool and the battery was above 85%.

However, starting two days later, I noticed a flickering effect on the lock screen in a specific area, especially when a notification appears. It doesn’t happen every time, but as of today (May 5), I’ve seen it occur twice.

Is anyone else experiencing a similar issue after the One UI 7 update? Would appreciate any feedback or suggestions.

Thanks!
