We are currently developing a game for android and ios in unity, using vuforia obviously. We just recently went through compatibility testing for the game. The Game has been tested on several phones and android versions without any kind of hiccups, except for the Samsung Galaxy S10, where the initialization of vuforia fails. If it helps I can provide an apk file.
I would be thankfu for any kind of advice or hint of possible causes.
Vuforia Version: 8.3.8
Unity Version: 2019.1.8f1
Device: Samsung S10
Android Version: 9
