Optimization of marker detection in Android app through AR Core and Sceneform.

We’re building an application for Android and iOS which uses AR for marker detection of different logos. The physical size of the logos varies between 18mm(0.7inches) to 35mm(1.37inches). The iOS application uses ARKit while the Android one uses ARCore for the marker detection. The problem - currently the Android one struggles when being used from a bigger distance where the iOS application would detect the markers with no problems. We’re looking for an Android developer who has experience with marker detection and is ready to help us in finding the optimal solution. Currently we’re using ARCore but we’re open for a switch if there is another library that would be an improvement for our needs.
