If the camera does not work even after a restart, it may indicate a hardware issue.
In my case, however, restarting the device or changing the system language temporarily restored the camera, but the issue reappeared after a few hours or a few days. When launching the Camera app, the preview appears briefly, becomes blurred (similar to the transition during lens switching), and then freezes after a few seconds.
Even after erasing the device and restoring from a backup, the problem reoccurred a few days later. Over time, the frequency of the issue gradually increased, which made it seem like something abnormal was progressing.
After that, I reset all settings and used the device with default settings only, and the problem has not recurred for over a week.
I have not yet identified which specific setting was responsible, but the non-default camera-related settings I previously used were:
• Video resolution set to 4K
• ProRAW controls enabled
• All “Preserve Settings” options enabled
• Liquid Glass disabled via Accessibility settings
Do any of you experiencing similar issues have these settings in common?
