Hi, I’ve been experiencing a strange issue with video playback on my iPhone. While watching videos, the image will suddenly shift it becomes more greyish, then sometimes briefly goes black, and then returns to normal bright quality. This can happen multiple times during a single video.
This is not limited to the Photos app. I’ve seen it happen:
- In the Photos app when playing videos I recorded myself
- In Snapchat when watching videos sent by others
- Occasionally in other social media apps as well
Additional details:
- HDR Video is turned off
- Apple ProRes is turned off
- Tried both 4K 60fps and 4K 30fps
- Camera format set to “Most Compatible”
- Low Power Mode is off
- Issue happens whether the phone is cool or warm
- Doesn’t seem related to the video file itself the same file exported to another device looks fine all the way through
- These exact same videos play back completely normally on my iPad with no brightness or contrast shifts at all
- I’m currently on the iOS 17 public beta, but this issue was happening before I installed the beta as well, so it’s not beta-specific
It almost feels like the display or system is switching between different brightness/contrast profiles mid playback, regardless of the app.
Has anyone else experienced this, and is there a way to disable this behavior so the brightness and color stay consistent during video playback?
Thanks in advance!
