Are you able to provide us device model and name running on a 64bit kernel?
We will work on the same hardware configuration.
How have you configured the multitouch emulator without an external device? We're working with Genymotion simulating multitouch but it's running only on a 32bit kernel.

no, sorry, i do not know all the models the issues were reported.
i'm not using another device at all for the emulator, as i wrote in a message earlier "to get this error on the emulator, you have to activate multitouch-support" ... so it's just for reproducing the issue... it wouldn't happen on emulator with activating it. i'm just zooming in with doubleclick.

however, i've been looking just now at a report from friday, where a user is reporting exactly this behaviour in play-store on a Galaxy Tab2 10.1, which isn't 64bit at all. ... now that leaves me rather puzzled.

We will better investigate on it.
I'll update you as soon as possible.

I'm really not able to find the post about Galaxy Tab you're addressing to.
May you link it here below?

these are the reports i find, which are connected to the problem:

i've searched for all connected ones, here you go ("recently" in the postings mean,s that we switched from jpeg to your pdf-lib):

Galaxy Tab2 10.1
the problem comes with the zoom to. It is to see only the upper left corner of the enlarged side - shifting the page is not possible.

Zooming is no longer possible Recently, zoom no longer possible! When zooming in, the picture moves to the upper left corner and can not be navigated. Please fix immediately!

another one is with a 2014 galaxy note 10.1 (from this user i got reported, that he's definitely using the last version in store).

Ok, was from your google play account that's why I wasn't able to find it.

May you provide some of your pdf file please?
