    Hi all,
    we are currently running into severe performance issues on some android devices.
    Seems like interactable Canvas / UI Elements are drastically reducing the frame-rate on some Android versions. We can reproduce the issue with the Tiny Arms Revenge Unity Example as well.
    Tap responsiveness on UI Elements becomes unreliable / slow.
    Changing the build settings from WebGL to Canvas to Auto seems to have no effect.
    On iOS performance was good on all devices.

    Here is a list of Android devices we were able to test on:

    bugged in mobile view NOT in desktop view:

    SM-g930f
    Android 8.0.0​

    bugged in mobile AND desktop view:

    SM-G960F
    Android 9​

    SM-N950F
    Android: 8.0.0​

    NOT bugged in desktop or mobile view:

    SM-G531F
    Android 5.1.1​

    NOT bugged in mobile and desktop

    SM-G900F
    6.0.1
    As you can see older Android versions seem to have no problems.

    Please have a look at it! It seems related / similar to that older Bug-report: https://forum.unity.com/threads/performance-consistency-on-android.599959/
    Also:

    Maybe it's not totally fixed / reapearing issue?

    Thanx a lot!

    Thanks for the feedback. Looks like it's affecting new Samsung phones. I can see it happen on a SM-J701M (Android 7.0.0) as well. Unfortunately, fixes towards runtime improvements are stalled until C# is out. Sorry for the inconvenience. I have noted this issue though.
