Live Text is an automatic optical character recognition feature in the camera app that is designed to make it easier to handle large amounts of written information. However, the iOS 15 feature is not compatible with all iPhone devices.
Apple's highly acclaimed Live Text feature for iOS 15 will only work with iPhones that use the A12 Bionic chip or newer, meaning users will need an iPhone from 2018 onwards to use it.
Live Text uses the device's intelligence to recognize text in a photo and give users the ability to perform actions. For example, users can search for and locate an image of a handwritten family recipe, or capture a phone number at a store with the option to make a call. Using the power of the Apple Neural Engine, the Camera app can also quickly recognize and copy text, such as the WiFi password displayed at a local cafe. Visual Look Up allows users to learn more about popular artwork and landmarks around the world, plants and flowers in nature, pet breeds, and even books.

Live Text can also be used to sort photos by location, scene, people, objects, and more by reading the text in the photos. Although iOS 15 supports a wide range of iPhones, including the first-generation iPhone 6S and SE, not all devices can run all of the new features. A disclaimer about Live Text states on Apple's website.
Available on iPhone with A12 Bionic and later.
iOS 15 “Visual Look Up” also requires newer devices
Apple's A12 Bionic chip debuted in 2018 in the iPhone XS, iPhone XS Max and the iPhone XR. This means that users need at least one of these iPhones to use the feature. Of course, users of the current range like the iPhone 12 will have no problems. Also limited to iPhones with the A12 Bionic chip is Apple's new city experience within the Maps app - "Visual Look Up".
Explore cities with unprecedented detail for streets, neighborhoods, trees, buildings, and more. Visit amazing 3D landmarks like the Golden Gate Bridge in both day and dark modes of the maps.
According to Apple, this feature also requires devices from 2018 onwards. iOS 15 is currently in beta and is expected to be released to all users worldwide in September this year. (Image: Apple)
