Complex Backward Navigation : User Research & A/B Test

Mobile applications are getting complex day by day. So crafting a good navigation across the app become a necessity. I was not very happy about the backward navigation system of Android. So I tried to rethink going back & did a very small user research. I have published the result on Behance with a detailed case study: https://www.behance.net/gallery/58997237/Complex-Backward-Navigation-User-Research-AB-Test
Would love your feedback.
