Galaxy S6 Default Example chrash

We are running the default Instant Tracking example on a samsung Galaxy S6. Its a Unity project with version 2017.3.1f1 and the latest Wikitude SDK, without anything else.


The example works as expected for about 2 - 7 minutes, but after awhile the app will chrash. LogCat reveals there is a Signal(11) (null refrence) which causes the app to be killed. We have tried running the app with Open GL 2&3, without 32 bit buffers, and with a locked orientation. So far none of these have helped and the same error occurs. Is there any way someone from the Wikitude team can take a look at this?


There are no unusual messages before this, it just suddenly has a null ref.
