If your iPhone XS LCD touch is malfunctioning in certain areas, do not panic! Here is a step-by-step guide to help you diagnose and potentially fix the issue. This comprehensive guide will help you avoid expensive repairs if a simple solution is enough.

1. Restart Your iPhone

One of the simplest steps you can take is to:

Press and hold the side button until the slider appears. Slide to power off and then back on.

Restarts can often resolve temporary software glitches and touch issues.

2. Remove Screen Protector or Case

Check if a screen protector or case is interfering with your device's touch functionality. Some screen protectors or cases can unintentionally block touch sensitivity.

Steps:

Remove the screen protector if applicable. Take off any accessories or cases.

3. Check for Software Issues

Ensure that your iOS is fully up to date as software updates can sometimes fix touch issues. Outdated software may be causing the problem.

Steps:

Go to Settings General Software Update (if available). If you have recently installed new apps or updates, consider uninstalling them to see if the issue resolves.

4. Reset All Settings

If software troubleshooting does not work, you can try resetting your iPhone's settings. This will not delete your data but will reset system settings.

Steps:

Go to Settings General Transfer or Reset iPhone Reset Reset All Settings (backup your data first).

5. Inspect for Physical Damage

Check for any visible damage to the screen or the device. Cracks or chips might mean that the LCD or touch layers are no longer in working order.

Steps:

Look for visible cracks or chips around the screen area. Turn the phone on and off to observe if the issue persists.

6. Restore Your iPhone

If none of the above steps work, consider performing a factory reset via iTunes or Finder. Ensure you back up your data first to avoid losing important information.

Steps:

Connect your iPhone to a computer. Open iTunes or Finder. Select "Restore iPhone" from the dropdown menu.

7. Seek Professional Help

If the issue still persists, it may be a hardware problem. In such cases, take your iPhone to an Apple Store or an authorized repair center for diagnosis and repair.

Important Notes:

Avoid attempting to open the device yourself unless you are experienced. This can void warranties or cause further damage. If your iPhone is still under warranty or covered by AppleCare, contact Apple support for assistance. If the screen is cracked, it will need to be replaced.

Additional Tips

Capacitive touch displays do not function properly in water or when your hands are too wet. Conversely, hands that are too dry can also affect touch sensitivity. Ensure your fingers are either damp or properly moistened before attempting to interact with the screen.

Try:

Mildly dampening your fingers with water from a damp cloth. Making sure your hands are not overly dry.

After dampening or drying your fingers, try interacting with the affected areas of the screen to see if the issue is resolved.

If these steps do not work, it is recommended to:

Power off and back on the phone. Contact Apple support for further assistance.

Remember, if your screen is cracked, professional repair is crucial to ensure your device’s functionality and aesthetic integrity.
