    Hello.
    I am developing an AR that is spawned and attached to a horizontal plane with touch inputs. But the issues are
    1) that whenever I open the app in Tab S7 a black blank screen is present. And when I reopen the app without closing from recent it works fine. Interestingly this issue is not present when I open the app with Redmi Note 8 Pro.
    2) Does not matter if I anchor the button to bottom or left the button seems to be snapped to certain places on the screen. I have yet to test this with another android device.

    Any ideas why these two might be happening and what should I do to fix them?

    Do you have
    com.unity.feature.ar
    installed in your project? I've seen some reports that this is causing blackscreen issues on Android, but if you install each of the packages individually the issue is fixed.

    Your second question sounds like you are having trouble setting up your canvas GameObject hierarchy. Not much advice we can give other than perhaps check out our sample app and see how our canvases are set up: https://github.com/Unity-Technologies/arfoundation-samples

    So regarding the anchor point I have found out that the display of Samsung Tab S7 FE is 2560 x 1600 instead of 1600 x 2560. Which I used the later one and thus I had unexpected results differentiating between the Unity display versus the actual result.
    I have yet to solve the black screen opening.

    Does anything appear in the logs related to AR or subsystems?
