Cinematic mode is frozen on iPhone 15 Pro Max on iOS 17.3

You may try some of these steps, please check after each step...

1. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
2. Close the Camera app and any other open apps. To force close an app on iPhone with Face ID, swipe up from the bottom of the screen and hold. On iPhones with a home button, double-press the home button and swipe up on the Camera app.
3. Reduce video resolution or frame rate: Cinematic mode is demanding on your phone's resources. Try switching to a lower resolution (like 1080p) or frame rate (like 30fps) and see if that helps.
4. Free up storage space: If your iPhone is low on storage, it can lead to app crashes and other issues. Try deleting unnecessary files, photos, or videos to free up some space.
5. Check for external app interference: If you have any third-party camera apps installed, try temporarily disabling them to see if they're causing a conflict.
6. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
   1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
   4. 
7. Make sure you have the latest updates installed.
   1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.

Hello, I have the exactly same problem with my Iphone 15 Pro.

For a solution I found that if you restart the phone, the cinematic mode will work fine.

"But apple really need to fix this thing."

Have a good day.
