Other causes include Smart HDR, new iOS updates, or the camera changing its exposure automatically.
Troubleshooting Prerequisites
Basic Troubleshooting
1. Clear the iPhone’s RAM
Too many apps running in the background can slow down your device and affect the camera. Clearing RAM isn’t always a direct fix, but it may help.
2. Disconnect the AirPods or Disable Bluetooth
Some users report that Bluetooth connections, like to AirPods, can sometimes affect camera performance.
3. Disable Night Mode or Deep Fusion on the iPhone
Using Night Mode or Deep Fusion can sometimes cause flickering, especially when there’s movement during long exposures or while Deep Fusion is processing. You can try turning these off.
3.1. Disable Night Mode
3.2. Disable Deep Fusion
4. Disable Macro Mode in the iPhone’s Camera Settings
Switching between camera lenses in Macro Mode can sometimes trigger flickering. Disabling Macro Control could help fix this.
5. Adjust the Camera Exposure
When the camera’s exposure isn’t set correctly, it will keep adjusting to the light, which can lead to flickering. Adjusting the exposure manually may help.
6. Match Video FPS to Light Frequency
Flickering can occur if the camera’s frame rate (FPS) doesn’t match the lighting frequency (like 50Hz or 60Hz). Changing the FPS setting in your camera might solve the issue.
7. Lock Camera Settings
Your iPhone might switch between different camera lenses when lighting changes, sometimes causing flickering. You can lock these camera settings, but remember this may turn off some automatic adjustments.
8. Reset All iPhone Settings
If a wrong setting is causing flickering, you can reset all settings back to how they were when you first got your phone. Don’t forget to back up your preferences first.
