• Source you installed the SDK: .unitypackage (.unitypackage or Unity Package Manager)
• Problematic Firebase Component: Analytics (Auth, Database, etc.)
• Other Firebase Components in use: Messaging and Crashlytics (Auth, Database, etc.)
• Additional SDKs you are using: Facebook, GameAnalytics, Appmetrica and Appsflyer (Facebook, AdMob, etc.)
• Platform you are using the Unity editor on: Windows (Mac, Windows, or Linux)

[REQUIRED] Please describe the issue here:

We observe approximately 50% abandonment at the first_open event. Through investigation, we found that certain devices (e.g., Samsung S23 Ultra and S24 Ultra on Android 13 and 14) only log first_open and app_clear_data in the initial session, with no further events recorded.

• Local Test Findings: Testing locally on these devices shows that Firebase initializes correctly, and events are sent to the server without any exceptions or errors.
• App Clear Data: We have verified that these devices are not manually triggering app_clear_data

Example User at Firebase User Explorer:

(Please list the full steps to reproduce the issue. Include device logs, Unity logs, and stack traces if available.) We don’t have specific reproduction steps, but during DebugView, events are being sent correctly, and there is no app_clear_data event.

Steps to reproduce:

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)?

What's the issue repro rate? (eg 100%, 1/5 etc)

What happened? How can we make the problem occur? This could be a description, log/console output, etc.

If you have a downloadable sample project that reproduces the bug you're reporting, you will likely receive a faster response on your issue.

Relevant Code:

it might be related with androidManifest file so i will share some of them; we are using firebase activity:

<application android:theme="@style/UnityThemeSelector" android:icon="@mipmap/app_icon" android:label="@string/app_name" tools:replace="android:allowBackup" android:allowBackup="false" android:isGame="true">
    <activity android:name="com.google.firebase.MessagingUnityPlayerActivity" android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen" android:exported="true">
      <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
      <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
    </activity>
    <service android:name="com.google.firebase.messaging.MessageForwardingService" android:permission="android.permission.BIND_JOB_SERVICE" android:exported="true"></service>
</application>

Some Permissions in use:

"android.permission.WRITE_EXTERNAL_STORAGE"
"android.permission.READ_EXTERNAL_STORAGE"

Initialization Code: Firebase initializes upon checking dependencies After initialization we start sending events

FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task =>
{
  var dependencyStatus = task.Result;
  if (dependencyStatus == DependencyStatus.Available)
  {
    IsInitialized = true;
  }
  else
  {
    IsInitialized = false;
  }
}, TaskScheduler.FromCurrentSynchronizationContext());
