These are the iPhone models that will not work iOS 11.

Not all Apple fans are happy with iOS 11, the new operating system the Apple company introduced at its annual developer conference in San Jose, California.

The new mobile platform will only work on phones and tablets with 64-bit architecture, so some iPhone and iPad models will automatically fall behind.Here you have the list of devices in which you can download and install iOS 11.

If you have an iPhone 5C or a previous model, iOS 11 will not work on your phone,

You can continue to use your phone with iOS currently available, purchase a new model or consider switching to another brand that works with different operating systems such as Android or Windows.

The phones behind.

The iPhone 5 and 5c phone lines, launched between 2012 and 2013, were two of the most successful and beloved by consumers of Apple products.

It is not uncommon to meet someone using an iPhone 4, as these phones were characterized by their strength and durability.

Unfortunately these models work in a 32-bit architecture.

This means that if you bought your device before 2013 you will not be able to count on the latest update of the operating system whose preliminary version will be released later this month and that will be distributed massively since September.

The Cupertino, Calif., Company also announced that iOS 11 will not run on fourth-generation or earlier iPads for the same reason as on laggard iPhones.

This transition was christened Apple as "a giant step for the iPhone and a monumental leap for the iPad".

The new operating system includes enhancements to the capabilities of its Siri mobile assistant, an application to manage phone files, a completely revamped version of the AppStore and simultaneous application function, among other innovations.
