iOS 9 allows recording Full HD and slow motion with the front camera for video clips, the Apple company preparing new functions for users who use its terminals. In the attached image you can see pieces of code from Apple's operating system that confirm the fact that these functions are currently being tested by engineers, most likely on terminals iPhone 6S si 6S iPhone Plus.
So far there have been no rumors indicating that the iPhone 6S will have a camera capable of recording Full HD video clips in 1080p format, or slow motion, at idle, with up to 240 fps, frames per second, but this is real .
If this information exists in iOS 9, then it is clear that Apple is testing Full HD and idle recording functionality with the front camera for certain terminals, but it is unlikely to be about any sold now.
iOS 9 is hinting at future device front cameras having: 1080p resolution, 240fps slow mo, panoramic capture, flash.
The current camera of iPhone terminals or iPad tablets is only able to record video clips in 720p format, but in no case in slow-motion, so Apple will probably present the new functionality in the fall.
There is a chance that the iPhone 6S will have as main functions these novelties that Apple is currently testing, and their inclusion will certainly please a large number of people, considering the popularity of selfies.
I say this because recording Full HD and slow-motion video clips requires a better main camera, so we can expect Apple to implement a 3-megapixel one instead of 1.2 or 2 megapixels.
Separate from the 1080p video recording, the front camera would also record panoramic images and will probably have a function that will imitate the use of an LED flash, these novelties not necessarily needing a new image sensor.
