Help I have an iPhone 11… the home button isn’t working.

If you're sure that nothing (cover or screen protector) interferes with your touch screen in the bottom area, and if you already tried (to no avail) a "forced" restart of your device (using these intructions:--> Force restart iPhone ), I suggest that you make an appointment (*) and have your device inspected at an Apple Store or AASP (Apple Authorized Service Provider) among this list:--> Apple – Location Selector. After checking it out, they'll give you all the available options.

Regards

Giulio

(*) You can do it:

• Online:--> Genius Bar Reservation and Apple Support Options - Apple;
• Contacting a local Apple Store or AASP among the list provided above;
• Using the "Apple Store" app, available and downloadable from AppStore.
