Hello bruby102,
Thank you for using Apple Support Communities!
I understand from your post that your Home button is not vibrating as expected even though you have it on the highest setting. The following article has some steps you can use which may help resolve this type of issue:
About the buttons and switches on your iPhone, iPad, or iPod touch - Apple Support
"What to do if a button or switch isn't working
Restart your device. If you can't restart your device, try to force restart it.
Remove any protective films and cases that might block the button or switch.
Check for debris or dirt around the button or switch, and clean with a soft cloth.
If the button or switch still isn't working, is damaged, or works intermittently, you might need to set up service for your device. Contact Apple Support, then follow the steps to complete your service request."
Best Regards.
