    This fix not work in 2019.3 and 2020.1.

    I see that this has been fixed in Unity 2019.3 and up, but starting with 2019.3, Unity is dropping support for Android versions lower than 4.4.

    Would it be possible to apply this fix to Unity 2019.2 as well so that we can still benefit from this fix for all currently-supported Android versions?
