Here are a few steps to help you troubleshoot a non-responsive home button:

1. Make sure your home button isn’t stuck in a depressed position. Tap it gently to make sure it isn’t stuck. If it does not respond, try using a soft cloth to clean around the button.
2. Check the software version. If your software is out of date, your home button may not be fully functional. Keep your software up to date to ensure optimum performance.
3. Test your home button. Visit the System Test or Home Diagnostics tab and press the home button. If you hear a beep sound, or the display changes, then your device’s home button is working as intended.
4. Restart your device. Press and hold the power button for a few seconds or until the device restarts.
5. Reset your device’s settings. If your home button still doesn’t work, try resetting your device to the factory settings. You may have to back up your data before resetting your device.
6. Contact a professional for help. If the home button still doesn’t respond, contact a professional technician for help.
