Can't hide status bar on some devices

On my device I can successfully hide the status bar by doing the following:

In my manifest I add the following:

<activity
    android:name=".SomeActivity"
    android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen"
/>

then in my styles:

<style name="Theme.AppCompat.Light.NoActionBar.FullScreen" parent="@style/Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

On my device (Samsung J7 Pro running Android 9), this is the result:

hidden

As you can see, the status bar and the action bar is hidden. But if I run this on a Huawei P20 Lite, this is the result I get:

not hidden

At the top there is a black bar where the status bar will be.

Why is this happening?

Create a values-v28 folder parallel to values folder.

Copy the theme content in new styles.xml file and add <item name="android:windowLayoutInDisplayCutoutMode">shortEdges</item>

<style name="Theme.AppCompat.Light.NoActionBar.FullScreen" parent="@style/Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowLayoutInDisplayCutoutMode">shortEdges</item>
</style>

Also, in Activity class add the following 

 public class MyActivity extends Activity {
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            requestWindowFeature(Window.FEATURE_NO_TITLE);
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
            setContentView(R.layout.my_activity);
        }
 }

Please check this link making apps notch friendly. Apparently it is happening because the device has a notch.
