Hi everyone,
I’ve been experiencing a strange recurring issue on my Samsung S95C OLED TV (2023, Tizen OS) while streaming Prime Video — and sometimes even Netflix and other apps.
Every now and then, the screen flashes horizontally, showing one or more thin lines, or it displays a half-screen distortion. It looks as if the image splits in two — the lower part fills with colorful static or noise, while the top continues the scene normally.
The issue happens when watching SDR content that’s being upscaled to HDR-4K. I’ve encountered these glitches with Smallville and Fear the Walking Dead on Prime Video, The Walking Dead and Daddy Day Care on Netflix, The Nanny on HBO Max, and Justified on Disney+.
Samsung Peru has only observed the issue on Prime Video, and at least in my presence they haven’t even tested other apps (possibly because the glitch can take much longer to appear).
I’ve already ruled out most causes:
It does not happen when I stream the same content through Chromecast or Apple TV using the same Wi-Fi connection.
It does happen across different apps (Prime Video, Netflix, HBO Max, Disney+).
The TV has had its main board replaced once by Samsung service, but the issue persists.
Samsung Peru insists the problem originates from the Prime Video app — even claiming I said it only happens there.
I’m trying to confirm if other S95C owners (or Samsung OLED users) have experienced the same behavior — whether with Prime Video or other streaming apps — and what, if anything, Samsung has done about it.
If you’ve noticed similar screen flashes, horizontal glitches, or half-screen artifacts, could you please share:
Your TV model and firmware version
Whether it happens in one app or multiple
Any workarounds you’ve found (specific settings, HDMI options, etc.)
Any info or patterns could really help identify what’s going on.
Thanks in advance for your time and feedback!
