Hi! In order to inspect the function of area target, I found information on your official website that provides recommended devices. And I finally got a Samsung Galaxy S21 5G, which is one of the recommended on your website. However, after I installed my finished apk into the cellphone, and used it to take pictures on my field trip, it didn't work as it is expected. When the cellphone caught the target that I intended to take pictures of, it simply vibrated, but it didn't show the object display that I had previously set on Scene. However, the water mark of Vuforia was still presented on the lower left corner of my phone screen.
Nevertheless, when I did the same operations on my colleagues' cellphones, Samsung Galaxy A42 5G and A70, the virtual object I had set in the apk was successfully displayed. Would you kindly tell me what the reason is? Btw, the version of Unity on my Galaxy S21 is 2019.4.21f1, the version of Vuforia Engine is 9.8.5, and the version of Android is 11.
Thank you for your kind reply.
