Here are the steps to follow to diagnose and troubleshoot when your iPhone touchscreen is not responding properly:
1. Check the Screen Surface
- Cleanliness: Make sure the screen is clean and fresh. Use a sturdy, lint-free cloth in order to remove fingerprints, dust or dirt.
- Without accessories: Screen protectors or casings that may interfere with touch sensitivity shall be removed.
2. Restart the iPhone
Sometimes a simple reboot can solve temporary problems.
- Models with Face ID: Press and hold the side button and one of the volume buttons until the power off slider appears. Subsequently, turn it back on.
- Models with start button: Press and hold the top or side button until the off slider appears.
3. Force a Restart if the screen is frozen
- iPhone 8 or later: Quickly press and release the volume up button, then the volume down button, and finally hold down the side button until you see the Apple logo.
- 7 and 7 Plus: Simultaneously press and hold the side button and the volume down button until the Apple logo is located.
- 6s or earlier: Press and hold the home button and the top or side button simultaneously until the Apple logo appears.
4. Disconnect External Accessories that cause problems to the display
- If you have a charger or other accessory connected to the Lightning port, disconnect it. Often, some defective accessories can cause problems with the display.
5. Update the Software
- Go to Configuration > General > Software update and check if an update is available. Apple updates usually minimize errors detected by the system.
6. Reset Configurations
If the problem persists:
- Go to Settings > General > Transfer or Reset iPhone > Reset.
- Select Reset all settings. This will not delete your data, but it will restore the default settings.
7. Restore iPhone
If no solution works:
- Back up to iCloud or iTunes.
- Restore the device from Settings > General > Transfer or Restore iPhone > Erase content and settings.
- Set it up as a new device and test the screen before restoring the backup.
8. Verify Hardware Problems
- If the screen continues to be unresponsive, there is most likely a physical problem.
- Inspect for cracks, water damage or recent impact.
Additional Tips
- If the problem occurs in certain applications, check if they need an update.
- Avoid using the iPhone while wearing gloves, as the touch screen may not respond well.
- Keep your device at a suitable temperature; extreme cold or heat can affect its performance.
