I use Kiwix for Android version 1.9 on my Samsung Galaxy S2.
Articles like chemicals (e.g. Magnesium) are cut on the left, the first words left are with missing first letters, see screenshot or test yourself.
This is on dewiki without pictures, from 12/2013 on my phone but should be broken on other Galaxy smartphones as well.
It is only in portrait mode, landscape has no cutting.
