Recent firmware updates to Samsung Galaxy S20 Ultra devices (with Snapdragon chipsets) have caused a regression in ARCore. These may manifest themselves as a black screen which is unrelated to the Vuforia Engine SDK.
Please see the following report for additional details: https://github.com/google-ar/arcore-android-sdk/issues/1308
Due to this regression, Vuforia Engine has disabled ARCore retroactively on the following device models:
Vuforia Engine's Model Targets and Extended Tracking features will continue to function on these models. However, Area Targets will no longer function. We will continue to monitor the situation and, once resolved, will re-enable ARCore on these device models once the issue is resolved by the OEM.
Thank you for your patience and continued support!
