Component used: androidx.core:core-splashscreen

Version used: : 1.0.1 , tested also with 1.2.0-alpha01- no change

Devices/Android versions reproduced on: tested on different Samsung devices like Samsung Galaxy S20(api level 33) and Samsung Galaxy Z Fold5(api level 34), does NOT reproduce on other brands(so far)

In my app I have a launching activity that starts, does something while showing the splashscreen and then starts the next activity and finishes itself. I've created a demo project where

    <activity
        android:name=".StartActivity"
        android:label="StartActivity"
        android:theme="@style/Theme.App.Starting"
        android:exported="true" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MainActivity"
        android:exported="true"
        android:label="MainActivity"
        android:theme="@style/Theme.MyApplication">
    </activity>

When the StartActivity is created it waits for 3 second, then start MainActivity:

public class StartActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    SplashScreen splashScreen = SplashScreen.installSplashScreen(this);

    super.onCreate(savedInstanceState);
    long start = System.currentTimeMillis();
    setContentView(R.layout.activity_start);

    splashScreen.setKeepOnScreenCondition(() -> {
        long now = System.currentTimeMillis();
        if (now - start > 3 * 1000) {
            startMainActivity();
            return false;
        }

        return true;
    });
}

private void startMainActivity() {
    Intent intent = new Intent(this, MainActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(intent);
    finish();
}

Steps to reproduce:

1. launch the app from launcher icon
2. the splash screen is shown for 3 seconds then the UI for MainActivity is shown
3. press the device Back button
4. press the device Recents button
5. choose the app

Results:

on Samsung devices: for 3 seconds there is nothing rendered as the app is frozen, no indication that it was clicked. Then the UI for MainActivity is shown.

on other devices: the splash screen is shown for 3 seconds then the UI for MainActivity is shown.

Here is the theme:

<style name="Theme.MyApplication" parent="android:Theme.Material.Light.NoActionBar" />

<style name="Theme.CustomStart" parent="Theme.MaterialComponents.DayNight.DarkActionBar.Bridge">
    <item name="colorPrimaryDark">@color/cardview_dark_background</item>
    <item name="android:windowBackground">@drawable/ic_launcher_background</item>
</style>


<style name="Theme.App.Starting" parent="Theme.SplashScreen">
    <item name="android:windowSplashScreenBehavior" tools:targetApi="33">icon_preferred</item>
    <item name="windowSplashScreenBackground">@color/purple_200</item>
    <item name="windowSplashScreenAnimatedIcon">@drawable/ic_launcher_background</item>
    <item name="postSplashScreenTheme">@style/Theme.CustomStart</item>
</style>

Note: when the app is clicked from Recent apps, the com.example.myapplication.StartActivity#onCreate is called.

If this is a bug in the library, we would appreciate if you could attach:
