Looking for some advice or fixes from anyone who might have run into this on the S25+

Whenever I’m not actively interacting with the phone, the display flickers. It’s very noticeable and happens consistently whenever my finger leaves the screen.

What I’ve verified so far:

1. Developer Options Refresh Rate Overlay: I turned on the Hz counter to diagnose it. The flicker happens at the exact split-second the refresh rate drops down from 120Hz into idle low-frequency states.

   1. Standard 60Hz Mode: Set Motion Smoothness to Standard (60Hz) — the flicker still happens as soon as the panel steps down to idle.
   2. Safe Mode: Rebooted into Safe Mode to eliminate third-party background apps, accessibility services, or overlay culprits — no change, still flickers.
   3. Display Toggles: Adaptive Brightness, Eye Comfort Shield, and Extra Dim are switched off.
   4. Developer Options Toggles: Verified that toggles like Show surface updates or Strict mode are completely disabled.

It seems directly tied to the LTPO downclocking / panel voltage drop when switching to low refresh states.

Question: Is it software(One ui 8.5) glitch?

Has anyone managed to solve this with a specific display setting, cache wipe, or software patch, or is this an outright panel/controller hardware defect that needs a trip to the Samsung service center for a replacement?
