14 DAY TRIAL // In a post published on realm.io's website, developer Genady Okrain presented a way to port the Live Photos feature available on Apple's iPhone 6s and 6s Plus to older iPhones capable of running iOS 9.
In order to get Live Photos working on your own iPhone, you have to download and build Okrain's sample Live Photos app, designed to help you both record and play Live Photos on your older iPhone.
The only requirements are an iPhone 6 / 6 Plus or older running an iOS 9.1 Beta release (if you don't have it yet, enroll in Apple's Beta Software Program for iOS) and Xcode 7.1 Beta 2 or later.
Having to use the Xcode 7.1 Beta release means that you also have to be enrolled in Apple's Developer Program, but unfortunately, there is no way around it since using an earlier Xcode version will not allow you to set your iPhone as a product destination.
To build the LivePhotoDemo app, you can use our tutorial on how to sideload iOS applications on your iOS devices (skipping the third step) and once you're done building the LivePhotoDemo application using our detailed procedure, you should have a new LivePhotoDemo application on your iPhone's Home screen.
The open source Live Photos sample app allows owners of older iPhones to test the iOS 9 Live Photos feature
After you launch the app on your iPhone, you will be able to record your own videos, as well as view them even though you do not own one of the new iPhone 6s or the iPhone 6s Plus models.
The only downside of using this method to bring Live Photos functionality to older iPhone models is that, as far as I've been able to see, Genady Okrain's LivePhotoDemo app will not allow you to save the Live Photos you record to your Photos library.
However, seeing that this is only a simple demo for the Live Photos feature, in the near future a developer with enough time on his hands might release an entirely functional application that would allow iPhone users to use Live Photos even if they haven't yet bought one of Apple's latest iPhones.
