TL;DR: Force a restart to clear temporary software glitches and clean the lens with a microfiber cloth to remove smudges obstructing the focus sensor. If issues persist, reset all settings or contact Apple Support for a potential hardware repair.
Step 1: Perform a Hard Restart
Software glitches are the most common cause of sudden focus issues. To perform a hard restart on the iPhone 15 Pro Max, quickly press and release the Volume Up button. Immediately after, press and release the Volume Down button. Finally, press and hold the Side button until the Apple logo appears on the screen. This process clears the RAM and can resolve temporary bugs affecting the camera module.

Step 2: Inspect and Clean the Lens
Physical obstructions are often overlooked but are frequent culprits. Use a clean, lint-free microfiber cloth to gently wipe the camera lenses. Avoid using paper towels or harsh chemicals, as these can scratch the glass. Check for any debris lodged in the gaps between lenses or around the ultrasonic sensor, which assists in focus. A clean lens ensures the camera can accurately read depth and focus information.
Step 3: Check for Software Updates
Apple frequently releases iOS updates that include bug fixes for camera performance. Navigate to Settings, then General, and select Software Update. If an update is available, install it. This step ensures your device is running the latest optimized code for the LiDAR and camera sensors, which often resolves compatibility issues with newer apps or system features.
Step 4: Reset All Settings
If the problem continues, a settings reset can help without erasing your personal data. Go to Settings, then General, and tap Transfer or Reset iPhone. Select Reset All Settings. Note that this will reset your Wi-Fi passwords, wallpaper, and privacy settings. After the restart, test the camera again to see if the focus issues have been resolved by restoring default system configurations.
Tips for Better Focus
Ensure good lighting conditions, as low light can confuse the autofocus system. Tap the screen to manually lock focus if the automatic system is struggling. Also, keep your hands steady to minimize motion blur, which can be mistaken for a focus failure.
