How do I fix my phone’s screen not responding to touch in certain areas?

1. Check your phone’s software updates
   On your phone, open Settings and make sure your device is running the latest software.
   If there’s an update available, install it.

2. Clean the screen with a lint-free cloth
   Clean the screen using a lint-free cloth lightly moistened with water or rubbing alcohol (aka isopropyl alcohol) to remove smudges or dirt.

3. Check for any obstructions
   Make sure there is nothing obstructing the phone’s screen and any of its sensors.

4. Follow the phone’s troubleshooting steps
   Look for recommended steps your phone’s manufacturer might have available.
