ARCore, black screen on Zebra TC51

Hey, I have an ARCore application which I'm trying to get to run on a Zebra TC51. I've been testing it on other Android devices (Huawei P20 Pro, Samsung S8) and it works fine. I know it's not on the list of supported devices, though the android version on the device is correct and I believe all the hardware is good enough. Is there anything I could do to get it working or am I at a dead end? This is with the latest ARCore version and Unity 2018.2.12f1.

Thanks guys!
