Comment 1 for bug 1631723

While I find very hard to think at a valid user scenario which could trigger this issue pretty often (and this could lead to a low importance), the bug currently exists.

Document Viewer just uses standard Ubuntu Components and can not edit the rotation behaviour in any way, therefore the bug needs to be fixed elsewhere.

I'm adding 'canonical-devices-system-image' as affected project, and contextually marking the report as Incomplete for 'ubuntu-docviewer-app', in wait for further informations from the Canonical engineers/managers.

Anyway, I checked on my Android phone and it seems that the OS always delays the screen rotation as long as there's an on-going touch event (e.g. 'onPressed' event).

This is something it would be necessary to implement in Ubuntu too (in the Ubuntu UI Toolkit, or whatever manages screen rotation - i.e. Mir or the Unity8 shell).
