Description chris hu 2017-09-18 19:26:08 UTC
This issue is happening at least in Xamarin.Forms2.3.3.180 and on iOS/Android platforms. 
This happens when the last row height is taller than its previous row. Based on my observation, Xamarin.Forms ListView seems to remember the last recorded Row Height(which is the previous shorter row) and use that height value to scroll to the end of list. In this case, if the last row's taller height is not taken into scrolling calculation. 

This bug is already reported here but marked as resolved but in fact it is not resolved.

Could you please upload a reproduction project displaying the behavior and verify that the issue has not been resolved as of 2.4.0-pre2? 2.3.3.180 is a rather old version and there might have been a fix in the interim.

Possible duplicate of 59817, or perhaps related. Marking as a duplicate for now as the newer bug has a reproduction project which was asked for (and refers to this bug in particular).
