RecyclerView dissappearing items

I have following issue.

Fragment with RecyclerView -> navigate to next fragment -> navigate back popBackStack() -> RecyclerView doesn't show items

It happens every other time(adapter instance inside Fragment always the same)

Adapter's itemCount always return's > 0 but I've checked that no onCreateViewHolder/onBindViewHolder method was called and also LayoutManager instance is present

This behavior happens on Samsung G7(don't know about other Samsung devices but everything is OK on Nexus, Xiaomi, LG)

setHasFixedSize(true)

adapter.setupData(content)
rv_test.adapter = adapter

/*setupData method*/
items.clear()
items.addAll(data)
notifyItemRangeInserted(0, data.size)

 <androidx.coordinatorlayout.widget.CoordinatorLayout
    ...
    <androidx.recyclerview.widget.RecyclerView
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:overScrollMode="never"
                    android:clipToPadding="false"
                    android:focusableInTouchMode="true"
                    app:layout_behavior="@string/appbar_scrolling_view_behavior"
                  app:layoutManager="androidx.recyclerview.widget.GridLayoutManager"
                    app:spanCount="2"
                    android:scrollbars="none"/>
...
</androidx.coordinatorlayout.widget.CoordinatorLayout>

You are adding data and notifying of an update before you are actually setting the adapter on the RecylerView.

Change:

adapter.setupData(content)
rv_test.adapter = adapter

To:

rv_test.adapter = adapter
adapter.setupData(content)
