I recently purchased the Samsung ue50ru7100 model.
When watching prime video 4K hdr content on the native app I seem to have intermittent green flashing and colour flickering numerous times an hour. However do not seem to have any issues on HD content or 4K on the Apple TV app. Can you advise on how to fix this?
Thank you for reaching out, is the prime app the only app that you're having issues with?
Strange, I seemed to encounter this issue too last night with my RU7400 while watching the second season of Jack Ryan in 4k HDR. Would flash with green/red bars a couple times an hour aswell as randomly getting a little brighter. There was also an issue where one scene was completely black apart from the very bright parts of the scene.
Not sure whether this is an amazon app issue or a TV issue as havent tried any other shows since.
EDIT: I've managed to capture some pictures of this happening today. These artifacts usually only show for one or 2 frames.
If this is the only app this is happening with, we would recommend you reach out to their development team directly. The email contact we have for their team is firstname.lastname@example.org.
