If your iPhone camera freezing happens mainly in Video mode, the issue may be caused by limited storage, temporary software glitches, an outdated iOS version, or too many apps using system resources. Video recording also puts more demand on the camera and processor, especially when using high-resolution settings. Try closing background apps, restarting your iPhone, freeing up storage, and checking for iOS updates. If the camera still freezes after these steps, the problem could involve the camera hardware or a deeper software issue that may require Apple Support.
