Snapchat Added Dual Camera Feature for only its iOS Users.

This Feature will roll out for Android Users after some time.

This feature offers four layouts, namely horizontal, vertical, picture-in-picture and cutout.

 It also allows Snapchat users to add creative tools like music, stickers and lenses.

The horizontal layout divides the screen into two parts from the horizontal center with the upper one...

...capturing the rear view and the lower one capturing the front view or vice-versa.

The vertical layout divides the screen into two parts again but from the vertical center with the left side...

...capturing the rear view and the right side capturing the front view or vice-versa.

The picture-in-picture layout shows the front (rear) view in a circular form which is pasted on top of the rear (front) view camera...

while the cutout layout allows users to erase the background of the front image and paste it on the rear-view image.
