Issue confirmed. I will try to improve algorithm, as workaround you can choose 
manual crop and remove croppind on bad pages/set correct manually.

I noticed that the version 1.6.6, which I run on my phone, does not have this 
bug.

I failed to find the attached file, so not sure if this is an issue I 
encountered.
Anyhow, I will describe my problem below.

For me, if a PDF file contains colored pages, auto cropping always fails after 
navigating a few pages.  monochrome pages doesn't have this issue.

I'm using v2.1.14 on Samsang Galaxy MEGA.
