HDR videos in photos sometimes play just audio with a black screen
When playing videos in the photos app, occasionally, all of my HDR videos are suddenly affected. The thumbnail for every HDR video will show an image of what the video is. When I select an HDR video and try to play it in photos, the audio plays correctly, but all I see is a black screen for the duration of the video. At the bottom of the screen, there is that tiny slider which all of the images for the as it plays with a bar you can move around, idk what it is called. The slider shows all of the images for the video as normal over the rest of the screen which is black while the HDR video plays. I’ve tried messing with the brightness using my control center when this happens but the screen is still black just for HDR videos though, nothing else. Restarting iphone, resetting wifi etc. does not fix it. I know someone else with this same issue as well. I have not tried playing videos in iCloud. It seems to be a strange issue because it only happens occasionally, however when it occurs it affects all HDR videos only, then I try again sometime later and it is back to normal, it seems to randomly go away. This last time this bug occurred, I noticed that I had reduce white point turned on in my iphone settings. I am not sure if this is related to the issue or just a coincidence, however while I was playing an HDR video with my brightness up all the way, the video was playing as a black screen with audio, I clicked three times on the lock button on the side of my phone to do the accessibility shortcut to unreduce white point, and the images for the video immediately appeared when ai did this. I then looked at the other HDR videos in my photos, and they will also play normally. Then, I reduced white point using the same shortcut and turned my brightness back down on control center. I went back to photos and now the HDR videos are still playing normally even with white point reduced. I will try this shortcut again if the playback of HDR videos become affected again.
