How can I fix the grainy and shaky video quality on my iPhone 15 Pro Max

Clean the Camera Lens:- Use a microfiber cloth to gently clean the camera lens and remove any dirt or smudges that could be affecting image quality. [1]

Disable Macro Control:- Go to Settings > Camera and turn off the Macro Control feature. This can sometimes cause issues with the camera's autofocus and lead to blurry or grainy video. [1]

Update to the Latest iOS Version:- Check for and install any available iOS updates, as Apple may have released software fixes to address the camera problems. Updating your iPhone's software could help resolve the video quality issues. [1][2]

Restart Your iPhone:- Perform a full restart of your iPhone 15 Pro Max, as this can sometimes clear up software-related camera problems. [1]

Remove Accessories:- Take off any camera lens protectors or phone cases that may be interfering with the camera's performance and causing the video quality problems. [1][3]

Use a Tripod or Gimbal:- For the shakiness issue, use a tripod or gimbal to stabilize your iPhone and eliminate camera movement during video recording. This can significantly improve the smoothness of your footage. [1][5]

If these troubleshooting steps do not resolve the grainy and shaky video quality, you may need to contact Apple Support, as there could be a hardware defect with the camera on your specific iPhone 15 Pro Max device. [1]
