I am trying to initialize multiple cameras at once just like a bothie feature in nokia phones,

As of now only one camera can be initialized at a time and other camera gets disposed off automatically, And also when I print the available cameras length it always prints 2 even though my device has three cameras in the back and a camera in the front, Is there any specific reason to that?.

This is how one of the camera gets disabled (Green Area) on initializing multiple cameras at once.The Sample image shows a screen with two halves the upper part for the primary camera (camera[0]) and lower for the secondary camera (camera[1] which is disposed)
