We are using fabric crashlytic tool and tracking the following error message for few android devices and could not find the reason, it seems like unity’s internal bug or something, if you have idea please let me know.

We have a lot of them for a loong time (covering Unity versions from late 5.4.x to latest 5.5.2f1 release). It’s around 20 or more, all happens on various ASUS devices (most on ASUS_T00F model). They really spam our Crashlytics spawning about 20 similar issues, all somewhere in libunity or libmono .
All crashes are real, they happens for a new users (without any user profile) only, so we’re loosing that users. I can summarize and give link to them later, or it’s probably a time to file a bug.
