Hi, Samsung. Thank you for the amazing S23 Ultra. I love the display, but there's one big issue with HDR playback, which can make HDR videos look worse than SDR. When watching an HDR video, it starts really good, bright and colorful, but then the brightness automatically lowers itself. You can fix this temporarily by decreasing brightness then increasing it again, but then it'll lower itself again in few seconds.
1. Adaptive brightness off or on doesn't make a difference.
2. Video Brightness normal or high doesn't make a difference.
3. Using different apps or different offline video players or different files, doesn't make a difference.
If you search here you'll find a LOT of posts about this same issue, but Samsung never acknowledged it.
Please look into this, it's such a great phone but this issues is making it worse than my previous phone, the Galaxy A52s 5G.
Samsung lowers HDR brightness on all of their S Models, and only they can fix it. But not enough people are complaining about this, even big YouTubers don't know about this problem.
