This fails on tablets / foldables:

<RelativeLayout android:id="@+id/rlMain" android:layout_width="match_parent" android:layout_height="match_parent" android:animateLayoutChanges="true" android:background="@color/toolbarBackgroundGrey" android:focusable="true" android:focusableInTouchMode="true" tools:ignore="RtlCompat">

Replacing linearLayout with ConstraintLayout works
