We came across an issue when installing our app on older iPhones (tested on 6 & 8).
When initializing the app we get the error (iPhone 6) "Video unsupported by hardware: may not play smoothly or play at all.", instead of the video feed, we get a black screen and the app crashes a few seconds later. I see Vuforia starting the camera with a profile for iPhone 7 and wonder if that might be the issue (Starting camera with profile for iPhone7,2, 750.1). We tried changing the Graphic API settings in unity as well as the app architecture but no luck.
Do you know how to fix the issue?
Attached is the full log.
