Hi, my back camera and flash aren’t working. Nothing happened, nothing broken, just stopped working, please help me with that

If you already tried (to no avail) all the steps provided in this support article:--> If the camera or flash on your iPhone, iPad, or iPod touch isn't working, 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.
