Hi,

Try to use OPEN GLES 3 with the app.

If this doesn't work, could you please provide a logcat dump? ( please provide the entire log, I would want to see Vuforia init sequence etc.)

1. Once log should be with the screen issue, shown in the jpg

2. Second log from Oppo f9.

Thank you.

Here is the logcat file for Radmi K2 pro for weird color behavior during opening camera.

Hi, 

In the attached log I am not able to see Vuforia Engine being init. 

Furthermore I would want to highlight the fact that we support following devices:

https://library.vuforia.com/articles/Solution/vuforia-fusion-supported-devices.html

Your mentioned devices are not on the list.

As a general rule, Vuforia should work with every ARCore certified device however we are not able to test every device to ensure optimal experience, hence we have the recommended device list. ( link above)

Please attach a logcat dump with vuforia being initializing and also try the core sample app ( available on the unity asset store) on the device and let me know if the issue is still reproducible. 

Thank you.
