iOS developer Hamza Sood has managed to find clues in the iOS 9 code that reveal some major changes are in the pipeline for the FaceTime front-facing camera on Apple iPhones.
The first major change is expected to be a resolution bump. iOS 9 brings support for 1080p video capture with a FaceTime camera, which means we could finally see Apple upgrade to a front-facing camera capable of shooting 1080p videos with the iPhone 6s and 6s Plus. While the FaceTime cameras on the iPhone 6 and 6 Plus are definitely not unimpressive, the 1080p video capture support will definitely be a major upgrade.
The other major change is expected to be support for capturing up to 240fps slow-motion videos at 720p resolution using the FaceTime camera. Currently, only the rear camera on the iPhone 6 and 6 Plus are capable of shooting 720p slow motion videos at 240fps.
Last but not the least is support for a front-facing camera flash. This is a bit surprising as so far we have seen this feature only on a few mid-range selfie-focussed smartphones such as the Sony Xperia C4 and the Asus ZenFone Selfie.
